After three long years, the wait for another Ryder Cup ends this week as the United States and Europe take to the fairways and greens of Whistling Straits. 

Europe are the holders but the USA start as favourites for many observers, with home advantage and a formidable-looking team. 

There will be shocks along the way and there will be some expected stars of the show who end up taking a back seat as unlikely heroes emerge. 

Captains Steve Stricker and Padraig Harrington will have their own ideas of who might be best placed to make a telling impression. 

Here, Stats Perform looks at four players who could make a huge impact across the weekend in Wisconsin. 

UNITED STATES: Super Spieth ready to show his teeth

Jordan Spieth has been a resurgent force this year, finishing second at the Open Championship and in a tie for third at the Masters, while at the other two majors he finished a respectable 19th and 30th. 

The American also ended a four-year wait for a victory on the PGA Tour with a sweet win in his home state at the Texas Open in April and is primed to cap a fine year with a strong Ryder Cup. 

Spieth has mentioned in the build-up that he loves the course set-up at Whistling Straits, which he feels provides scoring opportunities on almost every hole. 

The 28-year-old also referenced his previous Ryder Cup success. He has collected eight points from a possible 11 in fourballs/foursomes, a 73 per cent scoring rate. Only Tom Watson, Arnold Palmer and Jack Nicklaus have a better ratio among USA players in the team format. 

UNITED STATES: Nice guy Finau just the man for Stricker's superstars

American teams in the past have been accused of…well…not exactly getting along. Having the ultimate good guy in the team is sure to boost morale and Tony Finau certainly fits that mould. 

But make no mistake, Finau is a guy with real pedigree – even if sometimes he hasn't quite been able to convert that into wins (his triumph at the Northern Trust last month was only his second PGA Tour title and first in five years). 

On his Ryder Cup debut, he was one of few bright notes for Team USA, with Finau winning two of his three matches – including a singles win over the otherwise unflappable Tommy Fleetwood, setting the second-best points ratio (66.7 per cent) in the American team after Justin Thomas (80 per cent, four points out of a possible five). 

Moreover, at the 2015 US PGA Championship, Finau finished 10th having shot four sub-par rounds at Whistling Straits. Finau is the sort of character who can really flourish at a Ryder Cup, particularly with home support behind him. 

EUROPE: Europe eye trophy Rahm raid

Jon Rahm is the man for the big occasion. He is the only player to have secured a top-10 finish at all four majors this year, while he is also Europe's most recent victor at one of the leading events, having won the U.S. Open. 

The world number one's Ryder Cup debut did not go entirely to plan in 2018, as he won only one of his three matches, but that triumph was in a singles match-up with Tiger Woods – only Tiger's second loss in the format. 

Now established at the forefront of the sport, Rahm will expect to be the man to lead Europe to glory with an improved all-round showing, justifying his status as the bookmakers' favourite to be the leading points scorer at Whistling Straits. 

EUROPE: Viktor sounds like a winner

Belgium's Thomas Pieters was the top points scorer five years ago at Hazeltine, scoring four points but ending on the losing side. With Norway's Viktor Hovland relishing his debut on the team, could there be another surprise leader on the points board? 

Hovland played college golf for Oklahoma State and has been a familiar figure on the PGA Tour, so playing in America is second nature. He was low amateur at the Masters and U.S. Open in 2019, won the U.S. Amateur, and has come of age since, jumping to a career-high world ranking of number 10 in August. 

Eight top-10 finishes and just one missed cut since the turn of the year show what he brings, and that level of consistent play is bound to appeal to captain Harrington. 

"I'd like to think I have some fans out there that maybe won't necessarily boo against us," Hovland said this week. "But if they do end up doing that, that's what they're going to do. We're still going to play golf, and if they do end up doing that, that means we're doing something good." 

The 43rd Ryder Cup begins at Whistling Straits on Friday a year later than planned, with Europe seeking to retain the trophy after hammering the United States in Paris three years ago.

Delayed by 12 months due to the coronavirus pandemic, golf's most famous team competition makes its long-awaited return after Europe's 17.5 – 10.5 victory at Le Golf National in 2019.

Ahead of the action, Stats Perform explains the format of the contest.

HOW THE POINTS ARE SCORED

A total of 28 matchplay contests will be played across three days, with each contest worth one point.

If a match is level after 18 holes, Europe and the United States simply take half a point each.

As holders, Europe need only 14 points to retain the trophy, while their opponents must reach 14.5 to regain the Ryder Cup.

FOURBALLS AND FOURSOMES

The first two days are all about teamwork.

On Friday and Saturday, the morning sessions will involve fourball matches, each team fielding eight players in four pairings.

The fourball format is often known as better-ball as each duo takes their best individual score on each hole. So, for example, if Rory McIlroy makes a three and Jon Rahm a four, it is McIlroy's score that counts.

After the morning fourball sessions, things get interesting in the afternoons as eight more players from each side combine for foursomes action.

In this format, the two men on each team share one ball and take alternate shots, which can lead to some apologetic words between colleagues if a poor shot is played.

SUNDAY SINGLES

A whopping 12 points are up for grabs on the final day of the competition as all 24 competitors go head-to-head in singles matches.

While the captain determines who features on Friday and Saturday, with some players heavily involved and others lightly used or even left out altogether, every single team member is involved on Sunday.

The United States are favourites to make home advantage count and regain the Ryder Cup at Whistling Straits this weekend.

An emphatic 17.5-10.5 victory at Le Golf National in September 2018 saw Europe regain the trophy under Thomas Bjorn, as the likes of Francesco Molinari, Tommy Fleetwood, Sergio Garcia and Ian Poulter played starring roles.

Yet while Europe have won six successive home Ryder Cups, their recent record on American soil has been mixed.

We take a look at the last five editions of the event in the USA.

2016 - Hazeltine

Result: United States 17 - 11 Europe

Europe had won three Ryder Cups in a row ahead of the 2016 event, but they were in for a shock at Hazeltine.

Darren Clarke's hopes of masterminding victory suffered a hammer blow on the first morning as the United States, captained by Davis Love III, pulled off a clean sweep of the Friday foursomes.

Rookies Thomas Pieters and Rafael Cabrera-Bello impressed as Europe narrowed their deficit, but the USA regained control in the second fourball session and went on to triumph by a six-point margin, the talismanic Patrick Reed defeating Rory McIlroy in a dramatic opening singles match to set the tone for the hosts.

2012 - Medinah

Result: United States 13.5 - 14.5 Europe

Is it really nine years since the 'Miracle of Medinah'?

In the first Ryder Cup since the death of European icon Seve Ballesteros, the Spaniard's close friend Jose Maria Olazabal oversaw the most remarkable of comebacks to ensure Europe retained the trophy they had claimed at Celtic Manor two years earlier.

The USA were 10-4 up on Saturday afternoon, having won five of the day's first six contests.

However, Europe crucially won the last two fourball contests, with Poulter the architect of an astonishing turnaround in the anchor match.

Poulter and his team-mates then overhauled a four-point deficit in the singles, something that had only happened once before in Ryder Cup history, with Martin Kaymer sinking the winning putt to spark emotional scenes of celebration from the visiting team.

2008 - Valhalla

Result: United States 16.5 - 11.5 Europe

No European golfer in the professional era has claimed more major titles than Nick Faldo's six and the Englishman was also the most prolific points scorer in Ryder Cup history before Garcia moved past his tally of 25 at Le Golf National.

However, Faldo was nowhere near as successful in a miserable stint as Europe's captain, which yielded a heavy defeat to Paul Azinger's United States team at Valhalla.

The infamous 'sandwich-gate' incident - in which Faldo was photographed holding an apparent list of pairings only to then claim, somewhat unfeasibly, it was a list of lunch requests - was not the only gaffe made by the former world number one before the event had even begun.

Europe were then handsomely beaten when the action did get under way, trailing throughout on their way to a 16.5-11.5 loss.

Hunter Mahan was the leading points-scorer for the USA, who prevailed in seven of the 12 Sunday singles contests, but the likes of Anthony Kim, Boo Weekley, Justin Leonard and J.B. Holmes were among others to play starring roles.

2004 - Oakland Hills

Result: United States 9.5 - 18.5 Europe

In contrast to Faldo, the meticulous Bernhard Langer did not put a foot wrong in 2004 as Europe stormed to victory by a record margin at Oakland Hills.

Every member of Langer's team contributed at least a point, with wildcard selections Colin Montgomerie and Luke Donald among those to excel in a stunningly one-sided match.

In contrast, a USA team led by Hal Sutton and featuring three of the world's top 10 failed to deliver, with Chris DiMarco the only player to score more than two points for the hosts.

Montgomerie, in his penultimate Ryder Cup appearance as a player, famously holed the winning putt and went on to say: "That singles win over David Toms, in fact that whole week, rejuvenated me and my career."

1999 - Brookline

Result: United States 14.5 - 13.5 Europe

Prior to Europe's fightback at Medinah in 2012, the only previous instance of a team coming from four points behind in the singles came at Brookline, in distinctly fractious circumstances.

Mark James was Europe's skipper for an event sadly overshadowed by boorish abuse of visiting players by a partisan crowd and raucous scenes on the 17th hole on Sunday.

A mammoth putt from Leonard prompted an invasion of the green from the US team, even though Olazabal still had a putt of his own to come.

Ben Crenshaw's USA ultimately triumphed 14.5-13.5, but the 'Battle of Brookline' would be remembered for the wrong reasons.

In a subsequent autobiography, Sam Torrance - a vice-captain for Europe that week - described the final day of the 1999 event as: "the most disgraceful and disgusting day in the history of professional golf."

The 43rd edition of the Ryder Cup is almost upon us. A year later than initially planned, the finest golfers Europe and the United States have to offer will do battle at Whistling Straits.

Padraig Harrington's team will be looking to defend the title Europe clinched in Paris three years ago, while Steve Stricker's men will hope to make home advantage count as the USA look to win the tournament for only the third time since the turn of the century.

Ahead of the action in Wisconsin, Stats Perform looks back at some of the most memorable moments from tournaments gone by.

Miracle at Medinah, 2012

Where else to start other than a moment that is widely considered to be one of sport's greatest ever fightbacks. The "Miracle at Medinah" took place in Illinois nine years ago, with the Chicago crowd witnessing a remarkable European recovery, inspired by Ian Poulter – who will be playing again this weekend.

Europe were 4-10 down heading into the final day, with the USA needing just 4.5 points to win. Yet Poulter, who won all of his matches, got the ball rolling for the visiting team, who took 8.5 points from a possible 12 on the Sunday. Dustin Johnson, Zach Johnson and Jason Dufner offered the hosts hope, but Lee Westwood and Martin Kaymer won their matches to leave Tiger Woods needing to beat Francesco Molinari to secure a tie. The round was halved, ane Europe triumphed 14.5 to 13.5.

Battle of Brookline, 1999

Thirteen years prior to the Miracle at Medinah, the USA forged an incredible comeback of their own at Brookline, Massachusetts. Europe held a 10-6 lead heading into the final round, yet were pegged back as the USA, buoyed on by a vociferous crowd that riled some of the European players, with Colin Montgomerie coming in for particularly strong treatment, won the first six matches of Sunday's play.

Yet the decisive moment came when Jose Maria Olazabal – who would go on to lead Europe to victory at Medinah - lost three successive holes to Justin Leonard when he had been four up with seven to play. The match was tied on the 15th when the American holed a 40-foot putt, and on the 17th, Leonard struck a brilliant birdie, with the US team and fans storming onto the green in celebration as the half-point required to complete the comeback was secured. Olazabal still had a 25-foot putt to make to send the match to the 18th, only for the Spaniard's effort to trickle wide.

Torrance ends US dominance, 1985

The Belfry is entrenched in Ryder Cup history and, in 1985, Europe earned their first win in what was the fourth attempt since the team had spread to include the continent and not just players from Great Britain and Ireland.

Seve Ballesteros was in exceptional form, but it was left to captain Sam Torrance to sink a 22-foot putt, inflicting the United States' first defeat since 1957.

Clarke leads emotional European victory, 2006

Having taken a three-month break from golf following the loss of his wife, Heather, to cancer, Darren Clarke was named as a wildcard pick by Europe captain Ian Woosnam for the 2006 Ryder Cup, hosted in Clarke's native Northern Ireland at the K Club.

Clarke produced a performance for the ages, winning both of his pairs matches and going on to defeat Zach Johnson in his singles game. "I doubt there was a dry eye in the house," said Clarke afterwards, as Europe went on to secure an 18.5-9.5 win.

Langer fluffs his lines, 1991

Possibly the tightest Ryder Cup contest in history came at Kiawah Island, South Carolina, with the US taking a slim lead into the final day. However, by the time the final match rolled around, they needed half a point to reclaim the title.

It came down to the final hole, too. Bernard Langer required to hole a six-foot putt to tie his match with Hale Irwin, and Europe would keep their hands on the trophy. Yet he failed to do so, the ball rolling off the lip and away, with the US triumphing for the first time since 1983.

The concession, 1969

The Ryder Cup had been dominated by the United States from the end of World War II, with Great Britain (as the team was then) winning only one, in 1957.

However, the first tie in the Ryder Cup was recorded at Royal Birkdale in 1969, when American great Jack Nicklaus conceded a three-foot putt to Tony Jacklin at the 18th hole – the moment going down as one of the most famous gestures of sportsmanship. 

Bernd Wiesberger and Lee Westwood secured their places in Europe's Ryder Cup team as Billy Horschel prevailed on a dramatic final day of the BMW PGA Championship. 

Four automatic places were there for the taking at Wentworth. Tyrrell Hatton and Matt Fitzpatrick were already all but assured of their spots at Whistling Straits, with Wiesberger, Westwood, Shane Lowry and Justin Rose fighting to book their tickets. 

Lowry and Rose entered the final 18 holes with work to do and both ended up falling short. Rose's seven-under 65, which saw him finish three strokes behind Horschel on 16 under, was not enough to get him on either the European or World points lists. 

Irishman Lowry needed to finish in the top eight to qualify but endured a disappointing final day, a one-under 71 seeing him go 12 under for the tournament and leaving the 2019 Open champion down in tied 17th. 

Wiesberger carded a level-par 72 as he closed on 11 under, that score sufficient to dislodge Rory McIlroy from the European points list. 

Meanwhile, Westwood is set to equal Nick Faldo's record for Ryder Cup appearances by playing for Europe for the 11th time. 

Like McIlroy, Westwood qualifies via the World points list despite a five-over 77 that left him down in a four-way tie for 71st. 

At the sharp end of the leaderboard, it was Horschel who emerged from a tightly packed field thanks to his final-round 65. 

He was tied with Kiradech Aphibarnrat, Jamie Donaldson and Laurie Carter on 18 under, but a tremendous approach over the water at the last gave Horschel a simple putt for birdie. 

Carter was unable to replicate Horschel's feat, giving the American his second European Tour title of the year and his first triumph in a Rolex Series event. 

Graeme McDowell and Martin Kaymer have been appointed as vice-captains by Team Europe skipper Padraig Harrington for the Ryder Cup.

Both players bring a wealth experience to Harrington's backroom team for the rescheduled clash against the United States, which will take place at Whistling Straits in September – 12 months on from the original date that was scuppered by the coronavirus pandemic.

McDowell was also part of the set-up at Le Golf National in 2018, where Europe – led by Thomas Bjorn – hammered their American counterparts 17.5-10.5.

The Northern Irishman has featured four times as a player (2008, 2010, 2012, 2014), accumulating nine points from 15 matches – including claiming the winning point at Celtic Manor in 2010.

"I decided on Graeme as a vice-captain a long time ago. He was vice-captain in 2018 with me and I liked what he brought to the team room," Harrington said of the 2010 U.S. Open champion.

"He's quite an authority, confident in what he's doing and saying and knows the scene. The only reason he would not have been a vice-captain was if he was going to be a player.

"Graeme is a strong influence and the players look up to him. When he speaks, people listen, but he doesn't speak unless he's got something to say. I definitely saw that when he was vice-captain previously – players pay attention and follow him."

Kaymer too brings plenty of Ryder Cup experience to the table. The German has won 6.5 points from four appearances at the biennial tournament (2010, 2012, 2014 and 2016).

Undoubtedly his most famous contribution came when he sank the winning putt in 2012 to complete the "Miracle of Medinah", where Europe overturned a 10-6 deficit on the final day to retain the trophy.

Whistling Straits is also the scene of Kaymer's 2010 US PGA Championship triumph, which led to his debut in the Ryder Cup. 

"Martin is somebody I wanted as a vice-captain because he has a great personality and brings a calmness, a European element, and a lot of confidence with him," Harrington said of Kaymer, who also won the 2014 U.S. Open. 

"The fact that he won around Whistling Straits also brings that level of authority and assurance that you need.

"Martin will also bring a nice emotion to the team, which is very important. He's somebody who will help with the atmosphere, put an arm around a player or two and bring that level of authority and belief that we may need during the week."

Billy Gilmour is a huge part of Scotland's future after his standout performance against rivals England at Euro 2020.

Those were the words of Scotland boss Steve Clarke after his side impressively kept their last-16 qualification hopes alive with a 0-0 draw at Wembley on Friday.

Chelsea prospect Gilmour, 20, was handed his first international start for the massive match, which ended in the first goalless draw between the two nations in 33 meetings at Wembley.

Despite his inexperience, the composed Gilmour led Scotland for passes (44), completed passes (40) and passes in the opposition half (24), while he gained possession eight times, more than anyone else on the pitch.

Gilmour got a huge reception from the Scotland fans when he was replaced by Stuart Armstrong in the closing stages, with Clarke thrilled by what he had seen.

"It was nice for him to get that start, a big platform – he is a big player, Billy," said Clarke.

"I've said for a long time he'll be a big part of the future of Scottish football.

"We know what we've got in the camp, we'll try to manage that and keep a lid on things. Performances like that will do him no harm whatsoever.

"Stephen O'Donnell was exceptional, and Billy was just behind him. 

"Getting Kieran [Tierney] back into the three and having Scott [McTominay] there [in defence] gives us the platform to build from the back. Billy Gilmour and Callum McGregor [in midfield] are both good footballers. 

"We knew coming here we couldn't just sit and defend for 95 minutes, we knew when we had the ball, we had to take care of it and try to create our own chances. 

"That's what we managed to do."

Scotland ended the match with more attempts (11-9) and shots on target (2-1) than England, though the hosts edged the xG battle (1.6-0.7), given John Stones had headed against the post early on.

Having recovered well from their first loss to the Czech Republic, Scotland now face a must-win clash with Croatia at Hampden on Tuesday as Group D concludes.

Scotland captain Andy Robertson also had praise for Gilmour as he looked ahead to that contest.

"I'd put Gilmour's performance right up there," said the Liverpool defender.

"Nothing phases him. I believe he can have as many caps as he wants for Scotland. He's got a big future, but the here and now's pretty good for him too.

"I think we did deserve to win but we will take a point, it keeps us alive.

"But it's important we use the feeling, the feeling, the fans being happy with us going into Tuesday and try to use it to get a positive result to get out of the group."
