US swimming icon Katie Ledecky is back on top, earning her 22nd world title with a gold medal-winning 1,500-meter freestyle performance at the 2025 World Aquatics Championships on Tuesday.

Finishing with a time of 15:26.44, Ledecky now owns 25 of the top 26 times in the event's history and holds six World Aquatics Championships titles at that distance.

"Each one has meaning, and I love every race that I've had at Worlds over the years," the 28-year-old swimming star told broadcasters following her Tuesday victory.

That 22nd title brought Ledecky's combined Worlds total to an overall 28 medals, lifting the star to second on the all-time most decorated list where she trails only retired US men's star Michael Phelps's 33 podium finishes.

Earlier in the week, the Team USA standout took bronze in the 400-meter freestyle, coming in third behind China's silver-medalist Li Bingjie and Canadian sensation Summer McIntosh, who won the race with a time of 3:56.26.

Gold medals have been hard to come by for Team USA at this year's World Championships.

Other than Ledecky's win and the 100-meter butterfly title snagged by Gretchen Walsh on Monday, the US women have struggled to claim gold medals as they push to recover from the acute gastroenteritis that hit several team members at their pre-meet training camp in Thailand.

That stomach bug inhibited multiple US swimmers from traveling with the team to the Singapore meet, and saw contenders like 100-meter butterfly Olympic gold medalist Torri Huske pull out of initial heats.

"We're taking it a day at a time," said Team USA head coach Greg Meehan about the impact of the illness. "Obviously, this is not how we thought the first few days of this competition would go. But I'm really proud of our team."

The 2025 World Aquatics Championships runs through Sunday, and US star Ledecky has two events left to swim at the meet.

On Thursday, she'll compete in the 4x200-meter freestyle relay, before facing another showdown with rival McIntosh in the 800-meter freestyle on Saturday.

Preliminary heats kick off the night before at 10 PM ET, with finals seeing staggered starts beginning at 7 AM ET.

Live coverage of the meet airs on Peacock.

The PWHL is continuing to break records, as Sunday's 2025/26 Takeover Tour stop in Washington, DC, saw 17,228 fans pack into Capital One Arena to see the No. 2 New York Sirens top the No. 4 Montréal Victoire 2-1 — setting a new US women's hockey attendance record in the process.

The benchmark surpasses the previous US record set this past November, when the Seattle Torrent welcomed 16,014 fans to their inaugural home opener.

Sunday's DC crowd also sees the US mark inch closer to the overall professional women's hockey attendance record, set in April 2024 when 21,105 PWHL fans sold out Montréal's Bell Centre to watch the Victoire take on the Toronto Sceptres.

"Washington, DC, showed up in such a big way, and the energy our fans brought into the arena turned this game into something truly special," PWHL EVP of business operations Amy Scheer said of the first-ever PWHL game in the nation's capital. "Moments like this capture the joy of our sport and the momentum behind the league."

The third-year league is currently racing through its best-attended month on record, drawing more than 154,000 fans across the last 16 games while averaging crowds of 8,726 across all 49 games so far this season.

The Kansas City Current delivered some concerning news this week, with the NWSL club revealing that star striker Temwa Chawinga remains sidelined with an hip adductor injury while the league's 2026 preseason gets underway.

The team currently lists the reigning back-to-back NWSL MVP under a season-ending injury (SEI) designation, a category earned after Chawinga picked up the injury in mid-October, leaving the Kansas City attacker benched for the Current's quarterfinal loss to eventual 2025 NWSL champions Gotham FC.

"It's hard because of the nature of the injury," incoming Kansas City head coach Chris Armas told The Athletic last week. "With Temwa, we've got to be very careful, but she's looking great and doing lots of good work on the return to play."

Also on the Current's SEI list is standout winger Michelle Cooper, with the 23-year-old rising USWNT star suffering a foot injury in Kansas City's final regular-season match of 2025.

"It was a little bit of a tough ending here after, honestly, an amazing historic season," said Armas. "Hopefully they are back as soon as possible, but it's still unclear."

Both Chawinga and Cooper will have some time to recover before Kansas City kicks off their 2026 NWSL regular season against the Utah Royals on March 14th — with teams allowed to lift a player's SEI status any time once the season begins.

The world's top tennis stars are rolling in Melbourne, as the first round of the 2026 Australian Open wrapped early Tuesday morning with only a few ranked seeds suffering early defeats.

World No. 15 Emma Navarro was the highest-ranked US player to fall in the first round, with the 24-year-old exiting the season's first Grand Slam in a 6-3, 3-6, 3-6 loss to Poland's No. 50 Magda Linette on Sunday.

No. 11 Ekaterina Alexandrova also stumbled in the first round, with her Melbourne run ending in a three-set loss to Turkey's No. 112 Zeynep Sönmez on Saturday before No. 68 Peyton Stearns ousted fellow US star and 2020 Australian Open champion No. 30 Sofia Kenin in straight sets on Sunday.

Many contenders still remain in the hunt, however, as the entire WTA Top 10 cruised through their opening matchups to advance to the Slam's second round.

That said, fans will miss out on one highly anticipated showdown, as wild card entry Venus Williams's first-round loss ended the 45-year-old tennis icon's path to a second-round clash with US favorite No. 3 Coco Gauff.

The ongoing dominance of UConn basketball has started to break records, as the top-ranked Huskies humbled unranked Notre Dame 85-47 on Monday — keeping their perfect 2025/26 NCAA season intact.

Monday's 38-point margin of victory marked the largest in the teams' 20-year rivalry, with the win also snapping the Huskies' three-game head-to-head losing streak against the Fighting Irish.

"UConn showed why they're the best team in the country," Notre Dame head coach Niele Ivey said postgame.

Even more, UConn sophomore forward Sarah Strong added her own individual history to Monday's tally, becoming the third-fastest Husky to reach 1,000 career points, with the 19-year-old trailing only program legends Maya Moore and Paige Bueckers — who each did so in 55 games to Strong's 59 — in the race to reach that stat.

"I would love to see if anybody has scored 1,000 points by taking less shots than she's taking," said UConn head coach Geno Auriemma. "She's so efficient."

"It means a lot to me I guess, but I wouldn't be able to do it without my teammates," Strong said after leading the Huskies with an 18-point, 11-rebound double-double on Monday night.
