Coco Gauff is not expecting to win the Canadian Open as she manages the transition from clay to hard courts following the Olympics. 

Gauff fell short of a medal last month, losing to Donna Vekic in the singles while bowing out of the mixed and women's doubles with Jessica Pegula and Taylor Fritz. 

The world number two is one of the headline names at the WTA event in Toronto after a number of high-profile players, including world number one Iga Swiatek and Wimbledon champion Barbora Krejcikova, dropped out.

Her opening game of the tournament sees her face Yafan Wang, however, Gauff has tempered expectations as she prepares to defend her US Open crown at Flushing Meadows.

"I am not going into this expecting to win or anything. That would be great and it's the goal, but being realistic I was on clay three days ago," Gauff said. 

"I'm just trying to use this to see where I am and what I need to do to get ready for the US Open."

After her frustration in Paris, Gauff will have to wait another four years to win an Olympic medal, but has the comfort of the next Games being held on home soil in Los Angeles.  

And despite suffering disappointment in all three Olympic disciplines (singles, doubles and mixed doubles) this year at Roland-Garros, the American put her name forward to compete across the board again in 2028. 

"I would still do all three [events] again if that’s a possibility in '28," Gauff said. 

"I mean it's four years from now, I'll be 24, so I will still be on the healthier and younger side of things, and especially if the draw size for mixed is that small, I feel like that's one everyone wants to play.

"I had a great experience, from not being able to go to Tokyo to being able to go here, I just feel like LA, I'll hopefully be on the podium.

"I just feel like that's what my life consists of, having a disappointing result and then the next time is the best thing in the world."

Steve Kerr warned the United States must not "get lulled to sleep" by the fact they have already beaten Serbia twice recently.

The USA cruised past Brazil to reach the semi-finals of the Olympics, and Nikola Jokic's Serbia are next up.

Serbia have already faced the USA in the group stage, with the four-time reigning Olympic champions winning 110-84.

The USA also beat Serbia by 26 points in a warm-up match prior to the Games, but Kerr is taking nothing for granted ahead of Thursday's clash.

He said: "We can't get lulled to sleep because we beat them twice.

"We have to be prepared for their best effort. We've got to think about what they are going to do differently.

"Jokic, I guess he could play 40 minutes. What else do they have up their sleeve?"

It was a sentiment echoed by LeBron James.

"Every game is its own test. No matter what happened in the first two, it's about what goes down Thursday night," he said.

"So we need to lock in our film session, lock in during the day on Thursday, and then come out and be ready to go."

Jokic inspired Serbia to an Olympic-record comeback against Australia in the quarters.

How Serbia plan to manage Jokic's minutes is an intriguing question, but Joel Embiid is setting himself up to face the reigning NBA MVP for over 40 minutes.

"I guess we'll be ready for that," said Embiid.

"If that's what they think they have to do to try to beat us, then they won't hesitate to do that."

Iga Swiatek is sure of her place at the WTA Finals after it was announced the world number one had qualified for season's grand finale.

The season-ending tournament will take place in the Saudi Arabian city of Riyadh for the first time, and will be held in November.

Swiatek, who won bronze at the Paris Olympics last week, has become the first player to secure her place at the Finals.

The 23-year-old has scooped five titles in 2024, including the French Open, which she has won four times.

“It's a great feeling to qualify for the WTA Finals for the fourth year in a row," said Swiatek, the reigning WTA Finals champion.

"I hope that the performances of the eight best players of the season will give a lot of joy to the fans all over the world."

Swiatek will become the youngest player to appear at the WTA Finals for four consecutive years since Victoria Azarenka (2009-2012).

After been knocked out early on in 2021, Swiatek reached the semi-finals in Fort Worth in 2022 before triumphing in Cancun last year.

Kyle Schwarber homered three times, doubled and matched a career high with seven RBIs as the Philadelphia Phillies rallied for a 9-4 victory over the Los Angeles Dodgers in a matchup of division leaders on Wednesday night.

Schwarber led off the game against Gavin Stone with his first home run of the night and delivered a two-run double in the fifth to get the Phillies within 4-3. His three-run shot off Joe Kelly capped a five-run sixth and he took Michael Grove deep in the ninth for his 27th of the season.

The seven RBIs were the most by a Phillies player since Carlos Ruiz had that many against Atlanta in 2012.

Schwarber’s three-homer game was the second of his career, the other coming on June 20, 2021, for Washington against the Mets. He had seven RBIs one other time, on July 28, 2019, for the Chicago Cubs at Milwaukee.

Freddie Freeman drove in three runs for the Dodgers, who had their lead in the NL West sliced to three games over surging San Diego and Arizona. That is their smallest lead since April. 

Surging Diamondbacks sweep Guardians

Josh Bell homered twice and Eduardo Rodriguez won his season debut as the Arizona Diamondbacks remained red hot with a 5-3 win over the first-place Cleveland Guardians to complete a doubleheader sweep.

Ketel Marte, Geraldo Perdomo and Corbin Carroll each hit two-run homers to give the Diamondbacks a 7-3 victory in the opener.

Randal Grichuk went deep in the second game for Arizona, which won for the 12th time in 14 games and has won seven consecutive series, reinforcing its hold on a NL wild-card spot.

Rodriguez signed with the Diamondbacks in December but had been sidelined with a left shoulder strain. He allowed three runs and four hits over 5 2/3 innings and Justin Martinez loaded the bases in the ninth before striking out Lane Thomas for his second save of the series and his career.

Josh Naylor, Jose Ramirez and David Fry hit home runs in the doubleheader for Cleveland, which has lost a season-high five straight and had its AL Central lead cut to 3 ½ games over Minnesota.

The Guardians still own the best home record in baseball at 35-20.

Santander’s blasts power Orioles

Anthony Santander homered from both sides of the plate and Jackson Holliday added a two-run shot to lead the Baltimore Orioles to a 7-3 win over the Toronto Blue Jays.

Eloy Jimenez added a two-run double for the Orioles, who rebounded after losing Tuesday’s series opener to tie the Yankees for first in the AL East.

Baltimore trailed 3-2 when Holliday went deep for the third straight game in the seventh inning to score Jimenez, who hit an infield single.

At 20 years, 274 days, Holliday is the youngest player in AL history to homer in three straight contests.

Santander hit a two-run shot off Bowden Francis in the first inning and belted a solo shot as a right-handed hitter in the eighth. The homers were his 33rd and 34th, a career high.

Santander leads the majors with 25 homers since the start of June.

Naomi Osaka put her Paris Olympics disappointment behind her as she eased to the next round of the Canadian Open in a straight-sets win over Ons Jabeur.

Osaka fell at the first hurdle to Angelique Kerber at Roland-Garros last month, but was back to her best as she emerged a 6-3 6-1 victor in Toronto. 

The four-time grand slam champion wasted no time in stamping her authority on proceedings, earning a two break points to take a 3-0 lead early on. 

And that would prove decisive, with the world number 95 seeing out the rest of her service games, closing out the first set with a love game. 

Jabeur would have no response to Osaka's stunning display, with the Japanese finding another pivotal break before winning the remaining three games to confirm the win. 

Osaka will face Elise Mertens in the round of 32 after the Belgian beat Katie Volynets in straight sets earlier in the day. 

Data Debrief: Osaka over Olympics disappointment

Having suffered disappointment in Paris, Osaka responded in emphatic style upon her return to the court and will want to continue that momentum moving forward. 

Osaka converted all three of the break points she had, winning all eight of her service games. 

It proved to be a difficult day at the office for Jabeur, who uncharacteristcally served seven double faults throughout the contest compared to Osaka's four. 

Rafael Nadal has withdrawn from the US Open, claiming he would be unable to give 100% effort should he participate.

Nadal, who played in both the singles and doubles at the Paris Olympics, skipped Wimbledon earlier this year in order to feature at Roland-Garros.

However, after losing to Novak Djokovic in the singles and then failing to reach the medal matches alongside Carlos Alcaraz in the doubles, Nadal has elected to miss this season's final major and instead ready himself for the Laver Cup, which will take place in September.

It means the 38-year-old, who has triumphed four times at Flushing Meadows, may well have featured at the last major of his extraordinary career.

In a post on social media, Nadal wrote: "I have decided not to compete at this year’s US Open a place where I have amazing memories.

"I will miss those electric and special night sessions in NYC at Ashe, but I don't think I would be able to give my 100% this time.

"Thanks to all my US fans in particular, will miss you all and will see you another time.

"Best of luck to all for the always amazing US Open! My next event will be the Laver Cup in Berlin."

The Utah Jazz have signed forward Lauri Markkanen to a five-year, $238million contract that includes money added to next season’s salary and four additional years through the 2028-29 campaign.

The 2022-23 All-Star and NBA Most Improved Player will see his salary increase from $18million to $42 million next season before earning $196million from 2025-29.

“I’m excited to get this extension done,” Markkanen said. "I’m excited to get back to work and build with this franchise.”

The Minnesota Timberwolves selected Markkanen with the seventh overall pick in the 2017 NBA Draft before dealing him to the Chicago Bulls in a draft-night trade.

Markkanen went on to earn First-Team All-Rookie honours in 2017-18 before Chicago traded him to the Cleveland Cavaliers in August 2021.

He spent one season with the Cavaliers before they dealt him to Utah in the trade that sent Donovan Mitchell to Cleveland.

Markkanen averaged a career-high 25.6 points in his first season with the Jazz in 2022-23 while adding 8.6 rebounds per game. He was named an All-Star for the first time as well as the NBA’s Most Improved Player.

The 27-year-old Finland native followed that campaign by averaging 23.2 points and 8.2 rebounds last season.

Markkanen's 1,004 made 3-pointers rank third all-time in NBA history for players seven foot or taller behind Dirk Nowitzki (1,982) and Channing Frye (1,049).

Brandon Aiyuk seems set to leave the San Francisco 49ers after he was granted permission to speak to other teams.

Contract talks between the 49ers and their top wide receiver have stalled in recent weeks.

The Pittsburgh Steelers, the New England Patriots and the Cleveland Browns have all been credited with an interest in Aiyuk, who had 1,342 receiving yards last season, a career-high.

And San Francisco coach Kyle Shanahan has now confirmed Aiyuk has been allowed to open talks with other teams.

He said: "You're always disappointed when you can’t keep hold of all your players and it’s not going exactly right.

"I don't like losing anybody, so that’s why I am hoping it does work out here. But right now, we don't have that solved.

"You want everybody out there. You truly understand the business side of our league and what these guys do and what they have to go through in these deals.

"Whether it’s a hold-in or a holdout, this stuff is pretty common and you've just got to be patient with it as a coach."

Asked about signing a replacement if Aiyuk were to leave, Shanahan added: "Brandon's a great player, so it's really hard to be better when you lose a great player.

Zak Brown has admitted to being shocked by McLaren's competitive performance in the Formula One world championship this season.

McLaren sit just 42 points adrift of Red Bull in the Constructors' Championship, with lead driver Lando Norris also second to Max Verstappen in the standings.

The team have achieved podium finishes in their last 10 races, and they are well placed to challenge across the back half of the campaign.

Brown, however, was not expecting such success so soon.

"If I were to sit here and say I'm not surprised, that would be disingenuous," Brown told BBC Sport.

"Red Bull had such an advantage over everyone and Mercedes has been so dominant.

"I felt like we'd continue to close the gap. Did I think we would be here at the summer break, one race away from getting the lead?

"That race would have to be first and second and fastest lap, and do I think it's going to happen like that? No. But if we keep the same trajectory we've been on the last six, seven races, we'll be where we need to be by the end of the year.

"I thought we might get where we are now by 2025. I didn't think we would be where we are now in 2024. But I'm not complaining."

Both Norris and Oscar Piastri have claimed their maiden race wins this season indicative of an increasingly competitive McLaren.

Brown credits team principal Andrea Stella, who was appointed ahead of the 2023 season, for the growing success.

"He unlocked the talent that we already had here," Brown said. "We've got approximately 1,000 people here in F1. I changed three. But it was three leaders. So, 997 are the same people who gave us the [uncompetitive] car at the beginning of 2023.

"A leader's job is to get the most out of their people and that's what we didn't have previously. We weren't able to let the talent we have in here flourish.

"Andrea communicates very well. He listens very well. He's very hard-working. He's very technical. He leads by example. All the traits you would want in a great leader. He unlocked the potential this team clearly had sitting there."

While Piastri continued McLaren's podium success at the Belgian Grand Prix, Norris could not make gains in the driver standings despite Verstappen having to deal with a 10-place grid penalty.

He finished fifth, one place behind Red Bull’s reigning champion. Brown, however, sees these experiences as a learning curve for everyone.

"We've all made a variety of errors, which to me are learning experiences," he reflected.

"I thought [Mercedes team principal] Toto [Wolff] was accurate with his comment. He said: 'Well, sometimes you figure these things out once they've kind of been put on your plate.'

"So if I look at the mistakes we've made - whether those are drivers or us, kinda doesn't matter; we're one team - we wouldn't make these mistakes again. We're learning. And I think maybe because we have got where we are quicker than we thought, it shows we still have learning to do.

"Lando is trying to fight for a world championship. He's going for it. He's learning, as are we. So I'm not concerned about it."

Holger Rune made a strong start at the Montreal Open as he defeated Roberto Bautista Agut 6-2 3-6 6-2.

Rune, who withdrew from the Olympics due to a wrist injury, had been set to face Milos Raonic in the first round.

However, Raonic withdrew just moments before the match was due to start, so lucky loser Bautista Agut filled in.

It left Rune having to swiftly adapt to a new opponent, but despite a wobble in the second set, the Dane was generally in control throughout Tuesday's contest.

"It was a challenge for sure," Rune said. "It's never easy coming back after a little break — not the longest break, but for me, I'm very young and luckily I haven't been injured much. It was difficult but I think I managed to find the rhythm quickly.

"It was kind of tricky. It's two completely different game styles. I kind of had to adjust from one tactic to another in five minutes. Luckily, I played Bautista before so I had a clue, and obviously he's been on Tour for many years, so I know him very well.

"It was not easy. I was expecting a big server and trying to manage to get in the rallies with Milos, and now it was a completely different story. I needed to attack much more and play on my terms."

Next up for Rune, who has won 13 of his 15 opening-round matches this season, is a tie against Pablo Carreno Busta.

Data Debrief: Scandi style

Since the format’s inception in 1990, world number 17 Rune is now the fourth Scandinavian player to claim 30+ wins from an opening 50 ATP Masters 1000 matches.

He joins Stefan Edberg (41), Magnus Gustafsson (32) and Casper Ruud (31) on that list.

Jonathan Cannon pitched six strong innings and Andrew Benintendi hit a two-run homer as the Chicago White Sox ended an American League record-tying 21-game losing streak with a 5-1 victory over the Oakland Athletics on Tuesday night.

The White Sox won for the first time since July 10 after their 21-game skid matched the 1988 Baltimore Orioles for the longest in AL history. They avoided the major league record of 23 straight losses set by the 1961 Philadelphia Phillies.

Cannon allowed his only run on Zack Gelof’s home run and five other hits with two walks and five strikeouts for his second major league win.

Dominic Leone, Chad Kuhl and John Brebbia finished with three hitless innings.

The White Sox took a 2-0 lead in the fourth inning when Benintendi’s home run off Ross Stripling scored Luis Robert Jr., who had singled.

Gelof’s 14th homer in the bottom half cut Oakland’s deficit in half, but Chicago extended to a 4-1 lead in the sixth on Andrew Vaughn’s RBI single and a wild pitch by Michel Otanez.

Astros’ Valdez falls just short of history

Framber Valdez came up one out shy of his second career no-hitter, allowing a two-run homer to Corey Seager, before the Houston Astros held on for a 4-2 victory over the Texas Rangers.

Needing three outs for his second no-hitter in just over a year, Valdez walked Robbie Grossman to open the ninth before Ezequiel Duran grounded into a double play. After Josh Smith walked, Seager blasted the first pitch he saw into the right-field seats to get the Rangers within 4-2.

Josh Hader replaced Valdez and walked Marcus Semien but got Josh Jung to fly to the wall in right for his 23rd save.

Valdez had a perfect game through five innings and faced the minimum of 18 batters through six.  He won his third straight start and sixth consecutive decision, allowing one hit and three walks with five strikeouts.

The left-hander threw his first career no-hitter in a 2-0 win over Cleveland on Aug. 1, 2023. Teammate Ronel Blanco pitched the 17th no-hitter in franchise history against Toronto on April 1.

Yordan Alvarez hit a two-run homer in the ninth that ended up being the difference.

Surging Red Sox edge Royals

Dominic Smith scored the go-ahead run on a wild pitch in the sixth inning on a call that was overturned on a challenge, and the Boston Red Sox held on for a 6-5 win over the Kansas City Royals.

Smith doubled to open the sixth and moved to third on a single by Eric Sogard. After David Hamilton struck out, Smith charged home on a pitch by Seth Lugo that bounced in front of the plate and got away from catcher Salvador Perez. Perez chased the ball to the backstop, wheeled and threw to Lugo, who appeared to tag Smith for an apparent out.

The Red Sox challenged the call, which was overturned on review.

Masataka Yoshida added a two-run single later in the inning and Kenley Jansen got the final four outs for his 21st save.

Boston has won three straight and five of six to pull within one-half game of Kansas City for the final AL wild card.
