With the Grand Slam calendar nearing its close, stars flocked to this week's Western & Southern Open in Cincinnati to prepare for this year's US Open. Reigning Australian Open champion Aryna Sabalenka earned the win at the WTA 1000 event, taking down US player Jessica Pegula 6-3, 7-5 on Monday.

Fatigue impacts returning Olympic tennis players

With a uniquely crowded schedule this summer, partially due to the Paris Olympics, players entered this week with varying levels of fitness and fatigue.

China's newly crowned Olympic gold medalist Qinwen Zheng fell in the Round of 16 and Croatian silver medalist Donna Vekic failed to advance out of the Round of 64. Bronze medalist Iga Świątek reached the semifinals before losing to Sabalenka, while Pegula made this week's final match after competing for the US in Paris.

Fellow Team USA Olympians Coco Gauff and Emma Navarro fell in Cincinnati's Round of 32 and Round of 64, respectively.

Rest aided Sabalenka's Cincinnati Open win

On the other hand, Sabalenka missed Wimbledon due to a shoulder injury and, as a Belarusian athlete, did not participate in the Olympics. The world No. 3-ranked player returned to the hardcourt looking as sharp as she did at the beginning of the year, ultimately earning Monday's victory.

"This trophy means a lot, it is a really big achievement, especially coming after injury, with this fear of getting injured again," Sabalenka told press in Cincinnati. "My team did everything they could to make sure I felt as good as I can and I am proud of myself I was able to handle all of those emotions."

Tennis stars shift focus to US Open

The 26-year-old, who hit her first No. 1 ranking in September 2023 before relinquishing the title back to Świątek, will be hunting her third Grand Slam title and first at the US Open when play begins at the New York tournament next week. Sabalenka finished the 2023 US Open as the runner-up to Gauff, who earned her first major tournament title in three sets last September.

With a short turnaround and major surface change from the Paris Games, form and fitness could play a major role at this year's US Open. A number of athletes declined to participate in the Olympics in order to focus on the year's final Slam, and all eyes will be on Queens next week to see if those decisions paid off.

Game 1 of the 2025 WNBA Playoffs is in the books, with the top two seeds putting up more than 100 points each in blowout wins when the postseason tipped off on Sunday.

The No. 1 Minnesota Lynx opened the playoffs' eight-team first round with a 101-72 drubbing of the No. 8 Golden State Valkyries, as MVP frontrunner Napheesa Collier led scoring with 20 points while guard Natisha Hiedeman added 18 off the bench.

Elsewhere, the No. 2 Las Vegas Aces' 102-77 victory over the No. 7 Seattle Storm capped Sunday's slate, with reigning MVP A'ja Wilson leading the way with 29 points alongside double-digit performances off the bench from guards Jewell Loyd and Dana Evans.

The lower seeds walked away less unscathed, as Valkyries boss and Coach of the Year favorite Natalie Nakase picked up a technical foul for arguing a call in the game's second half.

"I want a fair fight, I really do. I want a clean fight, but I love the fact that both teams are playing their hearts out," she said afterwards, criticizing Sunday's officiating. "They're fighting. But I would like it to be fair."

"I understand it, but it's the playoffs," Lynx head coach Cheryl Reeve said in response. "Obviously, we fouled a lot at the end. But I didn't think that was a factor in the game."

Both Minnesota and Las Vegas are now one win away from advancing to the 2025 WNBA Playoffs semifinals.

The No. 2 Aces will look to sweep the No. 7 Storm at 9:30 PM ET on Tuesday, airing live on ESPN.

Then on Wednesday, the No. 1 Lynx will try to silence the No. 8 Valkyries at 10 PM ET, with live coverage also on ESPN.

The No. 5 New York Liberty secured the sole upset in the Sunday tip-off of the 2025 WNBA Playoffs, topping the No. 4 Phoenix Mercury 76-69 following a tightly contested Game 1 overtime battle.

Liberty guard Natasha Cloud dropped a game-leading 23 points on her former team, while Mercury star Alyssa Thomas neared yet another triple-double with 14 points, nine rebounds, and eight assists on the night.

"I'm proud of the way we stuck together, we weathered the runs they went on, and ultimately found a way to win," New York guard Sabrina Ionescu said after the game.

The newly healthy Liberty will hope for full availability in Game 2, though forward Breanna Stewart went down with a knock to the knee in overtime after posting an 18-point performance on Sunday.

"We're just hoping that she will be okay," New York head coach Sandy Brondello said after the game.

Brondello also confirmed that it was Stewart who asked for a sub in overtime after coming down hard on her left knee.

Concerns about the health of the two-time WNBA MVP — who recently returned from missing 13 games with a bone bruise on her right knee — overshadowed the defending champions' comeback win.

The No. 3 Atlanta Dream won their first postseason game since 2018 on Sunday, downing the No. 6 Indiana Fever 80-68 in Game 1 of the 2025 WNBA Playoffs as they continue making a case for this season's dark horse.

The Dream's starters shouldered the bulk of Sunday's scoring, punctuated by 20-point performances from forward Rhyne Howard and guard Allisha Gray, while the Fever's Kelsey Mitchell put up 27 points to give her injury-laden team a chance.

"This is [this roster's] first home game, period, in the playoffs," Howard reminded reporters after the win. "So for us to even have accomplished that much to have the home-court advantage, we knew we had to make it a good one."

Atlanta hasn't made it past the first round since the 2016 playoffs, but a dominant regular season has the team eyeing a long-awaited return to the WNBA semifinals.

This year's Dream won a franchise-record 30 games under first-year head coach Karl Smesko, while also leading the league in rebounds per game.

"This wasn't going to be a year that we were going to be satisfied with everybody telling us, 'Wow, you really improved over last year,'" said Smesko. "That's not what we're trying to do. We're trying to be the best team in the league."

The short-staffed No. 6 Indiana will look to halt the No. 6 Atlanta Dream's momentum on Tuesday, when the first round's Game 2 takes over Gainbridge Fieldhouse in the Fever's first home playoff game since 2016.

Jaedyn Shaw hit the ground running in her Gotham FC debut this weekend, as the NJ/NY club's recent $1.25 million-dollar signing scored against her former club in Friday's 2-0 win over the now-No. 5 San Diego Wave — helping boost the Bats to No. 3 in the 2025 NWSL standings.

"This year has been really difficult," an emotional Shaw said after the match. "I'm so grateful for this team and the opportunities I've gotten this year…. I'm extremely grateful for this moment."

The 20-year-old previously shattered scoring records during her time with San Diego, but struggled this year after her offseason transfer to the North Carolina Courage.

Already finding the back of the net for her new team, Shaw will look to put the past behind her as Gotham extends their climb up the table, having risen from No. 8 to No. 3 behind a four-game unbeaten streak that now includes three straight wins.

Gotham forward Esther González is also excelling, retaking the lead in the 2025 NWSL Golden Boot race by tallying her 13th goal of the season in the last minute of Friday's first half against the Wave.

With the club gaining momentum and the 2025 NWSL Playoffs looming, Gotham is looking to make a run to add a second championship trophy to their 2023 title.

"Even in the most difficult moments, they've stayed united, kept pushing together, and kept working hard. That's been our key," said head coach Juan Carlos Amorós after Friday's match.
