US sprinter Sydney McLaughlin-Levrone blew past the competition this week, becoming the first women's track athlete to run a sub-48 second 400-meter dash in almost 40 years on Thursday, when she won the event final at the 2025 World Athletics Championships in Tokyo.

The four-time Olympic gold medalist clocked a blistering time of 47.78 seconds, breaking her own US record en route to becoming the new world champion.

Notably, Dominican sprinter Marileidy Paulino — the 400-meter gold medalist at the 2024 Paris Olympics — crossed Thursday's finish line right on McLaughlin-Levrone's heels, joining the US winner in breaking the near-impossible 48-second barrier with a time of 47.98 seconds.

"You don't run something like that without amazing women pushing you to it," said McLaughlin-Levrone afterwards, crediting the impact of the other contenders on her own historic pace.

McLaughlin-Levrone's new time is now the second fastest in the sport's history, trailing only the 1985 world record of 47.60 seconds set by East Germany's Marita Koch.

Thursday's win also marked the 26-year-old's first-ever major international 400-meter flat title after historically dominating the 400-meter hurdles, making McLaughlin-Levrone the only athlete to hold world titles in both races.

"I felt that somebody was going to have to run 47-something to win this," Bobby Kersee, the sprinter's longtime coach, told The AP. "She trained for it. She took on the challenge, took on the risk. She's just an amazing athlete that I can have no complaints about."

The first round of the 2025 WNBA Playoffs ends on Friday night, when the No. 4 Phoenix Mercury and No. 5 New York Liberty return to Arizona for a winner-take-all Game 3 — with a trip to the semifinals on the line.

"The message is, 'Everybody keep our heads up. This is a series, and Phoenix is a tough team,'" Liberty star Breanna Stewart said ahead of Friday's matchup.

Still battling an MCL sprain in her left knee, Stewart hopes for more quality time on the court to help New York bounce back from the Mercury's Game 2 blowout win.

While neither team has successfully defended at home so far, Phoenix will look for a boost from the Mercury fans as they try to oust the defending WNBA champs.

"It's just nice for everyone to get a home game," said Mercury forward Alyssa Thomas. "[But] in order to win a series, you got to win on the road."

"You see how competitive, how balanced this is," said Stewart, commenting on the league's new home-away-home first-round format. "How important it is for these kind of series to be going back and forth."

It's win-or-go-home for both the No. 5 New York Liberty and No. 4 Phoenix Mercury in Game 3 of the 2025 WNBA Playoffs on Friday.

The high-stakes matchup will tip off at 9 PM ET, with live coverage on ESPN2.

The 2025 WNBA Defensive Player of the Year race ended in a tie on Thursday, as dominant seasons at both ends of the court saw Las Vegas Aces center A'ja Wilson and Minnesota Lynx forward Alanna Smith each receive 29 of the media panel's 72 total votes.

After finishing first this season in blocks per game (2.3), total rebounds (407), defensive rebounds (316), and combined steals and blocks (156), Wilson became just the fourth player in WNBA history named Defensive Player of the Year at least three times — adding this year's title to her previous 2022 and 2023 honors.

As for Smith, who picked up the award for the first time this year, the Lynx star ranked second overall in combined steals and blocks (135), third in both blocks per game (1.9) and total blocks (80), and tied for 10th in total steals (55) on the season.

Also snagging votes were Seattle Storm forward Gabby Williams, who came in second with nine votes, as well as Phoenix Mercury triple-double phenom Alyssa Thomas and fellow Minnesota Lynx star Napheesa Collier, who received three and two votes, respectively.

The win by both Wilson and Smith marks the first time in history that the WNBA Defensive Player of the Year honor has ended in a tie, reflecting both the top-notch level of talent on display across the league as well as the hyper-competitive nature of the 2025 end-of-year awards race on display across multiple categories.

Next up on the league's awards docket is Saturday's Sixth Player of the Year announcement, followed by the highly anticipated reveal of the 2025 WNBA MVP on Sunday.

The NWSL promises a tense mid-table battle this weekend, as the No. 4 Portland Thorns take on the No. 5 San Diego Wave with both teams looking to keep late-season lags at bay.

After strong starts, the Thorns and Wave each have just one win in their last five games, with San Diego aiming to snap a two-game losing streak after falling to Gotham last weekend.

Even more, both clubs currently sit in a four-way tie for points on the NWSL table, giving Saturday's match extra weight in potentially shifting the standings this weekend.

"It's a really important moment for us as a team," said San Diego head coach Jonas Eidevall. "Because adversity will happen to people or teams at various points, and everything about now is how we respond."

Portland will also look to regain ground, perhaps drawing inspiration from the past after announcing Wednesday that the club plans to retire legendary forward Christine Sinclair's jersey in an October 4th ceremony.

Sinclair established herself as the Portland Thorns' all-time leading scorer, retiring last year with 79 goals across all NWSL competitions — the second-most ever scored by an NWSL player.

No. 2 Las Vegas narrowly avoided a 2025 first-round postseason series upset on Thursday night, defeating the No. 7 Seattle Storm 74-73 in a deciding Game 3 to advance to the Aces' seventh-straight WNBA semifinals.

Aces star A'ja Wilson put her team on her back with another dominant performance, posting 38 points — including 25 in the second half — to outscore the rest of the Las Vegas lineup entirely.

"I am so proud of my team, we were resilient, that's what we need to be in these playoffs and I love each and every last one of them," Wilson said postgame.

Las Vegas got off to a slow start this year, but a late-season surge fueled by a renewed focus on depth saw the 2023 WNBA champs take the No. 2 playoff seed — and book yet another trip to the WNBA semifinals.

"I remember Chelsea [Gray] saying in a timeout, 'There's no time for my-bads anymore,'" said Wilson. "We have to play perfect basketball."

Up next for No. 2 Las Vegas is a No. 6 Indiana side punching above their weight.

That said, the Fever did score a 2-1 record against the Aces in the 2025 regular season — and Las Vegas's lone win over Indiana came back in June.

"They haven't seen the real Aces yet," Las Vegas head coach Becky Hammon said of the Fever. "They caught us when we were a bit in turmoil."

The Aces will take aim at Indiana in Sunday's 3 PM ET semifinals opener, airing live on ABC.
