Four-time Olympic gold medalist Sydney McLaughlin-Levrone maintained her 400-meter crown this weekend, completing her second straight 400-meter events sweep at the Grand Slam Track series' Miami meet on Sunday.

One month after completing the sweep at the first Grand Slam meet in Kingston, Jamaica, the 25-year-old US track star won Saturday's 400-meter hurdles with a time of 52.07 seconds before also taking Sunday's 400-meter flat event in 49.69 seconds — a race that earned McLaughlin-Levrone a $100,000 winner's check.

McLaughlin-Levrone has a veritable stranglehold on the 400-meter hurdles, dominating that race since her last loss at the 2019 World Championships.

In that span, she blasted through six world records across 12 straight victories — lowering the women's 400-meter hurdles world standard from 52.16 seconds to a blistering 50.37-second pace.

With two more Grand Slam meets in Philadelphia and LA in the coming weeks, McLaughlin-Levrone is considering a literal change of pace, temporarily switching to run the 100-meter events — a distance she hasn't competed in since 2018.

Should she take on the shorter sprints, McLaughlin-Levrone could find herself racing against the reigning Olympic champion in the 100-meter hurdles, Masai Russell — who notably posted the second-fastest time in the event's history, not to mention a new US record, by winning in 12.17 seconds on Friday.

McLaughlin-Levrone, Russell, and other track stars will next compete in the third Grand Slam Track meet in Philadelphia from May 30th through June 1st, before closing out the series in LA between June 27th and June 29th.

Star US distance swimmer Katie Ledecky is back to her old tricks, registering her fastest 1,500-meter freestyle in seven years — and the event's second-best time in history — at the 2025 TYR Pro Swim Series in Fort Lauderdale, Florida, on Wednesday.

The nine-time Olympic gold medalist finished the 30 pool lengths in 15:24.51, just missing the world-record 15:20.48 race time she posted in 2018.

Ledecky now holds the 1,500-meter freestyle's top 22 fastest times in women's swimming history — all of which would have won Wednesday's final race, where she defeated second-place finisher Jillian Cox — a University of Texas freshman — by a full 39 seconds.

Even more, Ledecky didn't slow down after her 1,500-meter performance posting her fastest 400-meter freestyle in nine years the very next day.

In the final lap of the race, the 28-year-old staged a comeback to pass Canadian teenage phenom and 2024 Olympic silver medalist Summer McIntosh and secure the win.

Her time of 3:56.81 just missed the US record of 3:56.46 that Ledecky previously claimed along with a gold medal at the 2016 Rio Olympics.

"I don't know if I ever thought I was going to be 3:56 again," Ledecky said in her post-race broadcast interview. "I'm just really happy with all the work that I've put in to get to this point."

The 2025 TYR Pro Swim Series continues through Saturday, with Ledecky competing in Friday's 200-meter freestyle final prior to racing in the 800-meter freestyle on Saturday.

Both races will begin at 6 PM ET on their respective days.

Live coverage of the meet will stream on Peacock on Friday before shifting to the USA Swimming Network on Saturday.
