The second Grand Slam Track meet of 2025 kicked off in spectacular fashion under the lights in Miramar, Florida—and right out of the gate, history was made.

Masai Russell stole the show, blazing to a 12.17 in the 100m hurdles to break the American record and move to #2 on the all-time list. She edged fellow American Tia Jones by just two-hundredths, with Jones jumping to #3 all-time in the process. That head-to-head thriller was just one of many standout performances on a night packed with fireworks: two national records, two world leads, and a wave of personal bests.

In the men’s 200m, Jereem Richards dipped back under 20 seconds for the first time in two years, clocking 19.86 to edge Alexander Ogando in a photo finish. Ogando’s runner-up finish came with a silver lining—a new Dominican national record. Marileidy Paulino kept the momentum going with a hard-fought win over Salwa Eid Naser in the women’s 400m, stopping the clock at a season-best 49.21.

Alison dos Santos continued his unbeaten streak in the men’s 400m hurdles with a dominant 47.97, while American sprinter Melissa Jefferson-Wooden scorched the track with a wind-aided 10.75 in the women’s 100m.

Distance fans weren’t left out either. World champion Josh Kerr made a statement in the 1500m, outkicking Olympic medalists Yared Nuguse and Cole Hocker in a confident, emotional win in 3:34.51. Ireland’s Andrew Coscoran shocked the field in the men’s 3000m, upsetting defending champ Grant Fisher. And Agnes Ngetich, fresh off her 10K world record, was untouchable in the 5000m, running a world-leading 14:25.80.

From wire-to-wire battles to all-time performances, Night 1 in Miramar delivered—and set the stage for a weekend of unforgettable action.
