Karolina Pliskova stayed in the hunt for a place in the last four of the WTA Finals with a 0-6 6-4 6-4 victory over Barbora Krejcikova, though her hopes hinged on Anett Kontaveit defeating Garbine Muguruza later in the day.

World number three Krejcikova did not have a win to her name in Mexico, losing to Kontaveit and Muguruza, but raced into the ascendancy on Sunday as she claimed the first set in just 26 minutes of an all-Czech tussle.

Pliskova, who had won both prior singles meetings between the pair, responded brightly in the second set before Krejcikova broke her fellow Czech's serve to take a 3-2 lead and seemingly edge closer to victory.

However, world number four Pliskova fought back by breaking in consecutive Krejcikova service games to level the match. The contest then teetered in the balance in the decisive set but, despite producing a double fault in the penultimate game, Pliskova downed Krejcikova to maintain hopes of an appearance in the final four in Guadalajara.

Wimbledon runner-up Pliskova won earlier in this tournament against Muguruza, who was set to face Kontaveit later on Sunday.

The 29-year-old Pliskova was sure to be paying close attention to that match. She needed Kontaveit, already through to the last four, to beat Muguruza and that would be enough to confirm the Czech's place in Group Teotihuacan's top two.

However, a win for Muguruza would see the Spanish sixth seed go through alongside Kontaveit, with Pliskova eliminated.

Bernardo Silva apologised to Portugal fans following a dramatic 2-1 loss to Serbia in Lisbon on Sunday that left the Selecao facing a World Cup qualifying play-off.

Portugal only needed to avoid defeat in order to finish top of Group A and secure an automatic qualifying spot for the tournament in Qatar next year.

Renato Sanches' early strike put the hosts in the lead, but Dusan Tadic levelled and Aleksandar Mitrovic headed in a 90th-minute winner to seal sensationally seal Serbia's World Cup spot.

Manchester City midfielder Silva pulled no punches with his verdict on Portugal's performance.

"[It was a] terrible game for Portugal," Silva told O Jogo. "We managed to score the goal early, but then we stopped playing. Words fail me. We have to do more than we did today.

"We have a play-off, where we'll give our best. At home, with 65,000 people we had to do better. I want to apologise because they came to see a game they shouldn't have seen.

"The plan was to try to win the game. To have the ball. Something that didn't happen in any moment of the game. That at home and with the quality of our players is unacceptable. We have to see what failed and try to improve from there on."

Joao Palhinha agreed with Silva's assessment of the team's negative performance, but insisted they are good enough to qualify for the World Cup.

"We are here to take responsibility," Palhinha told RTP. "We didn't play a good game, we just defended in the second half and Serbia ended up having happiness in the final minutes, but [qualification is] still within our reach.

"Serbia played a good game, but we had the capacity and level to be superior. We are very sad, the dressing room is on the wane for not having achieved the direct qualification, but we have to go chasing them in the next games, because we have more than value to be in the World Cup.

"Life is not a constant of victories, all people who are successful in life go through difficulties and this feeling has to give us more strength."

There was agony for Matteo Berrettini as he was forced to retire in his first match of the ATP Finals against Alexander Zverev on home soil.

Italian Berrettini appeared to suffer an abdominal injury when trailing 1-0 in the second set after Zverev won the first 7-6 (9-7) in their opening Red Group match in Turin on Sunday.

Sixth seed Berrettini dropped his racket and put his head in his hands as he grimaced after crashing a forehand into the net and underwent lengthy treatment to his left side.

The world number seven attempted to continue, but was clearly in pain as he served and duly brought the contest to an end at the Pala Alpitour.

Berrettini cut an emotional figure and was embraced by Zverev before being given a great ovation as he trudged off the court, with his opponent standing to applaud.

Zverev had saved two set points in the opening set and came from 5-3 down in the breaker to edge in front before the match came to a premature end.

Spain qualified for the 2022 World Cup in Qatar after a tense 1-0 victory over Sweden that was secured by Alvaro Morata's late winner.

Sweden needed to win in Seville on Sunday to top Group B but will go into the play-offs instead after Luis Enrique's home side saw out a nervy final match of their qualifying campaign to clinch the automatic spot.

Emil Forsberg had two clear-cut goalscoring opportunities for Sweden at the Estadio La Cartuja but was unable to test Spain goalkeeper Unai Simon.

Morata gave Spain victory with a close-range strike on the rebound with four minutes of the game left after Dani Olmo had seen his effort hit the crossbar.

Aleksandar Mitrovic's late winner saw Serbia seal their spot at the 2022 World Cup with a 2-1 win over Portugal in Lisbon.

Portugal went ahead after just two minutes as Bernardo Silva capitalised on a defensive error to set up Renato Sanches, who opened the scoring with an unerring finish. 

Dusan Tadic's deflected strike levelled the scores later in the first half, with Rui Patricio partially culpable for allowing the ball to cross the line.

Substitute Mitrovic completed a dramatic turnaround in the 90th minute as he headed in from Tadic's cross to send Serbia top of Group A and condemn Portugal to the playoffs.

Substitute Mitrovic completed a dramatic turnaround in the 90th minute as he headed in from Tadic's cross to send Serbia top of Group A and condemn Portugal to the playoffs.

Portugal enjoyed a dream start as Silva dispossessed Nemanja Gudelj before finding Sanches, who advanced into the area and rifled past Predrag Rajkovic.

Dusan Vlahovic thought he had equalised 10 minutes later as he struck towards the bottom-right corner, but his left-footed effort bounced off the post and away from danger.

Serbia did draw level in the 33rd minute when Tadic's fierce strike from the edge of the area took a deflection, causing Patricio to fumble into his own net.

The hosts came within inches of reclaiming the lead after the interval as Sanches' blocked effort was cleared against Rajkovic's back and rolled just wide.

Serbia appeared surprisingly conservative in the second half but Mitrovic, who headed wide only minutes before, grabbed a dramatic winner with just a minute remaining of normal time as he nodded in at the back post from Tadic's cross to ensure his country's place at the World Cup.

The Netherlands will have to do without the injured Stefan de Vrij when they face Norway in a decisive World Cup qualifier on Tuesday.

De Vrij suffered a hamstring injury in the closing stages of the Oranje's 2-2 away to Montenegro on Saturday and was replaced by Matthijs de Ligt.

The Inter centre-back has now been ruled out of the Netherlands' final Group G game against third-placed Norway at De Kuip, so De Ligt is set to starting alongside captain Virgil van Dijk.

Coach Louis van Gaal has not called up a replacement for De Vrij.

The Netherlands lead Norway and Turkey – who are away to Montenegro on Tuesday – by two points, and a draw should be enough for them to qualify for the tournament in Qatar next year due to their far superior goal difference.

It appeared to be mission accomplished for the group leaders when Memphis Depay's double put them in control at Podgorica City Stadium, but late goals from Ilija Vukotic and Nikola Vujnovic prevented them from getting the job done.

The Netherlands will not have the backing of a partisan crowd against Norway, as the game in Rotterdam will be played behind closed doors due to coronavirus restrictions.

Germany head coach Hansi Flick was pleased with his team’s 4-1 win in Armenia as they brought a successful World Cup qualification campaign to an end on Sunday.

Goals from Kai Havertz, Jonas Hofmann and a brace from Ilkay Gundogan saw the Germans home in Yerevan. The victory means that Flick has won all of his first seven games in charge of Die Mannschaft, scoring 31 times and conceding just twice.

It is also their joint-longest winning run this century (also seven in 2017). The last time Germany had a longer winning run was across 1979 and 1980, when they managed 12 in a row.

They finish their World Cup qualifying campaign top of Group J having won nine of their ten games, a comfortable nine points ahead of North Macedonia in second.

"We won 4-1 and achieved our aim of ending the group on 27 points," Flick said after the game. "It wasn't all brilliant, but the way we try to play football is great. You can see that the team always wants to attack and create chances.

"We defend high up the pitch and then allow them a few opportunities on the break, though that's just normal. We know what we need to improve on; we've got time for that.

"I'm satisfied with the team. We've won seven games together now, so I can only congratulate them. It's great as the coach to see the team enjoying themselves so much."

Thomas Muller was also pleased with the win, emphasising the importance of getting off to a good start in a "new era" for the national side.

"I think that was a good performance from us overall," the Bayern Munich attacker said. "It wasn't a goal-fest like against Liechtenstein, but we got the job done well. The first goal was important for us and was really well-made. We were concentrated and committed. It's a good way to finish off the campaign.

"A new era began in September for the first time since 2006. You can see that we've played well over the last three months and we want to continue doing so. It doesn't matter who is on the pitch, everyone will give their all and do their job.

"We may not have played any big teams, but we have performed really well at times. We can go into next year with a positive mindset now. We're happy."

Roberto Mancini insisted Italy must not forget what they have achieved recently as his side prepare for a crunch clash with Northern Ireland.

The Euro 2020 winners sit above Switzerland in World Cup qualifying Group C on goal difference alone, with both teams currently on 15 points after a 1-1 draw between the pair on Friday.

With only the team that finishes top progressing, slipping to second place would see Italy condemned to the play-offs as the Azzurri flirt with missing the World Cup for the second time in a row.

However, as Italy prepare for their final game with Northern Ireland – who are in third with eight points – Mancini implored his team to remember what they have achieved so far, having previously embarked on a world-record 37 matches without defeat.

"We mustn’t think negative thoughts," Mancini said at Sunday's pre-match news conference. "We know it’s an important match, we’ll go there aiming to win and know that Northern Ireland are difficult to beat here.

"If we do miss out, then we’ve got the opportunity of a make-up exam in March, but we want to go through tomorrow and that is what we must focus on.

"Nobody believed in us when we started this journey three years ago and we know there have been difficult moments along the way. It’s a delicate match tomorrow, but the lads mustn’t forget everything they have achieved already.

"They mustn’t feel so much anxiety, they have to play with freedom and concentrate on what needs to be done."

Italy, however, are by no means a certainty to cruise past Northern Ireland, given the Azzurri have never won in Belfast.

Indeed, a 2-1 loss in 1958 saw Italy miss out on the World Cup that year and Mancini appreciates the difficult task that awaits his team at Windsor Park.

"I don’t go back that far, but I do know the history," Mancini responded when asked about Italy's previous record in Belfast.

"It’s not an issue of scoring many goals, it’s about playing the game. Northern Ireland haven’t conceded a goal yet at Windsor Park in this group and there must be a reason for that.

"We have to win and if we score lots of goals that’s even better. We certainly won’t go for high balls into the box, as Northern Ireland are rather tall and that’s their bread and butter.

"We must try to play the ball quickly to feet, what we’ve been doing for the last three years, really.

"All the teams have injuries at the moment, but we remain a strong squad and will aim to get a positive result."

Lewis Hamilton acknowledged his stunning fightback victory at the Sao Paulo Grand Prix felt as good as his first in Formula One.

The Mercedes driver saw his Friday qualifying session result ruled out due to a DRS infringement, meaning he started the sprint race in last, but went from 20th to fifth, only for a five-place grid penalty to mean he started 10th on Sunday.

However, the Briton delivered a memorable win, gaining eight places early on and overtaking Max Verstappen with 12 laps remaining.

The reigning world champion cut Verstappen's lead in the battle for the title to 14 points with three races to go.

"It feels like a first as I haven't had a win for a long time," Hamilton said.

"I never thought we would close the gap like we did today when things just seemed to be going against us.

"It just shows you should never give up whatever you are facing. You need to keep pushing, keep tumbling and never ever stop fighting. That's what I have done this weekend.

"The team did an amazing job and Valtteri Bottas did a great job to [finish third and] get as many points as possible.

"I just pushed as fast as I could, but from last on the grid and another five-place penalty this is my hardest weekend I have had [this season]."

Hamilton has now won 17 races in the Americas (seven in Canada, six in the United States, two in Brazil and two in Mexico).

It means he overtakes the legendary Michael Schumacher as the driver with the most F1 victories across the four nations.

He dedicated the victory to his father Anthony and to the Brazilian fans who supported him at Interlagos.

He added: "My dad reminded me of when I was in F3 in Bahrain around 2004, when I started last and finished first - so this one is for my dad.

"I am so grateful for the incredible support I have had this weekend. I have not had this much support since Silverstone, and since then it has been really difficult.

"To hear these fans throughout the weekend has been humbling. I have been saying 'obrigado Brasil' because I am so grateful."

Next up is the Qatar Grand Prix and Red Bull driver Verstappen vowed to finish the campaign strongly as he eyes his first F1 title.

He said: "We tried everything we could today, it was a good battle but at the end we missed a little pace. But it was good fun.

"We still have a decent lead so today was a bit of damage limitation. I'm confident, in the coming races we will come back stronger."

Aaron Finch has hailed Adam Zampa as the player of the tournament after Australia beat New Zealand by eight wickets to claim a first T20 World Cup title.

David Warner claimed the official Player of the Tournament award after a scintillating performance with the bat, hitting 53 from just 38 balls in the final to finish as the second-highest run-scorer in the competition, his tally of 289 bettered only by Pakistan captain Babar Azam's total of 303.

However, Finch believes Zampa's contribution was even more important and heaped praise on the 29-year-old, who took 13 wickets in total.

Sri Lanka's Wanindu Hasaranga (16) was the only bowler to take more wickets in the tournament than Zampa, who also recorded the best figures in a single game (5-19).

"[Zampa was the] player of the tournament for me, controlled the game, got big wickets, super player," Finch said after the game. 

"Can't believe people wrote [Warner] off a couple of weeks ago, it was almost like poking the bear. Mitch Marsh, what a way to start, put pressure on from the start.

"Matt Wade came in under an injury cloud and got the job done. He came in in the semi-final alongside Marcus Stoinis and did the business."

Finch revelled in Australia's historic triumph and pointed to their eight-wicket victory over Bangladesh on November 4 as the turning point for their successful campaign.

"This is huge, to be the first Australia team to [win the T20 World Cup]," Finch continued. "So proud of how the guys went about the campaign.

"[The Bangladesh game certainly was the turning point], backs were against the wall. We had to fight and certainly did that, had some great team and individual performances."

Kane Williamson conceded Australia did not give New Zealand any leeway as Aaron Finch's side cruised to their maiden T20 World Cup crown.

Williamson, who was dropped on 21 by Josh Hazlewood, struck 85 from just 45 balls to guide his side to 172-4 from their 20-over allocation in Sunday's final.

That was the joint-highest score in a T20 World Cup final – along with Marlon Samuels' knock against England in 2016 – and the fastest-half century ever scored in the showpiece of the competition.

However, Williamson held those records for a short time as Mitchell Marsh, who blasted his first ball over square leg for six, delivered a brutal unbeaten 77 from 50 deliveries to see Australia over the line.

After Australia completed their second magnificent run chase in four days, following victory over Pakistan in the semi-final, Williamson admitted New Zealand's trans-Tasman rivals never gave his side a chance in the chase.

"We were trying to get a bit of a platform and the surface was holding a platform," Williamson said during his post-match interview on the field.

"We got what we thought at the halfway stage was a good total, but it was chased superbly by Australia.

"We made every effort to get a good total. Guys came out and committed to their plans. We weren't far away but having said that, credit to the way Australia chased that total. They did not give us an inch.

"I'm really proud of our teams efforts throughout the tournaments. We came here and gave it our best shot, but it wasn't good enough tonight."

Trent Boult, whose figures of 2-18 proved in vain, provided New Zealand with the briefest glimmer of hope when he bowled David Warner (53) in the 13th over.

But Williamson appreciated that Australia were a class above as he looked back on yet another final loss, previously losing to England in the 2019 World Cup.

"Australia are a team full of amazing players," he added. "Today they really turned it on.

"We finish this campaign and such is life in the international schedule is you move your focus. No doubt we're feeling this one a little bit.

"We had high hopes coming into the game. It's never nice. You sign up to these sort of things. It's just a shame we couldn't get the job done tonight."
