NASSAU — Throwing down the gauntlet to the rest of the world for the Paris Olympics, Team USATF went 4-for-4 in the finals they contested Sunday evening at the World Athletics Relays at National Stadium. Figuring in the repechage victory in the men's 4x400 at the beginning of the night's festivities, all five U.S. relay teams secured Olympic spots. Capping off a very successful night, the women's 4x400 was never challenged as they put together a world-leading 3:21.70 to win by more than three seconds. Quanera Hayes showed veteran savvy as she started with a 51.16 leg that allowed her to give Gabby Thomas a good lead going into the second circuit. Thomas, who took gold on the 4x100 less than a half hour previously, showed that she is a contender for major honors with a 49.58 split, and all Bailey Lear and Alexis Holmes had to do from there was get the baton around safely. Lear took on the difficult task of racing with a big lead and did so very well, splitting 51.33, while Holmes cemented a historic night with a 49.63 anchor leg. Another very strong lineup in the men's 4x100 saw Team USATF dominate from gun to wire on the way to equaling the fourth-fastest time ever by an American quartet, winning by almost a half-second in a world-leading 37.40. Only two other countries besides the United States have ever run faster. Courtney Lindsey powered around the first turn and the rout was on as he handed off to Kenny Bednarek. A stellar dash down the straight put Bednarek well ahead as he passed to Kyree King, and King was safe and speedy around the bend. After he safely made the exchange with triple World Championships gold medalist Noah Lyles, Lyles did, well, Noah stuff. Pulling away from the world he sealed the victory and made it 3-for-3 for U.S. relays. Tamari Davis blew open the women's 4x100 right from the gun, sizzling around the bend to give the stick to Gabby Thomas more than a quarter-second ahead of every other nation. Thomas maintained the lead down the backstretch and made a quick pass to Celera Barnes. Barnes quickly navigated the final turn, and it was up to Melissa Jefferson then. Jefferson, the 2022 Toyota USATF Outdoor Championships gold medalist in the 100, sped away from the field with a stunning 9.98 split to stop the clock at 41.85, a Championships record and the fastest time in the world in 2024. Facing a rematch in the mixed 4x400 with the Netherlands, the team that almost snagged the gold at last summer's World Championships, the U.S. opened with Matthew Boling, the only member of the world record-setting and world champion squad competing in this event. Boling acquitted himself admirably with a 45.11 to establish a solid lead. Lynna Irby-Jackson preserved that lead with a 50.10 on the second leg before Willington Wright's fresh legs enabled him to pad the lead a bit on a 45.18 split. Kendall Ellis closed it out with a well-paced anchor leg of 50.34 to give the Americans a gold medal and a Championships record of 3:10.73. Seeking redemption after a disqualification in the heats yesterday, the men's 4x400 made quick work of the first repechage section, running away with the fastest time overall at 2:59.95. Needing to finish in the top two of their section to guarantee a Paris berth, Jacory Patterson handled leadoff duties and passed to Champion Allison in second after a 45.54 split. Allison took the lead early and clocked 44.79 to handoff to Chris Bailey with a lead of a couple of strides. A sizzling 44.26 lap by Bailey gave the U.S. team an almost unassailable lead as Bryce Deadmon brought the baton home with a comfortable 45.36 anchor carry.
