FREEPORT, Grand Bahama — Team USATF swept the final four relays and won 24 medals, including 10 golds, Sunday to close out a comprehensively dominant performance at the NACAC Open Championships at Grand Bahama Sport Complex. The U.S. ended up with 63 total medals, 29 of them gold. Kaylin Whitney and Kyla Jefferson put the U.S. into a virtual tie with Jamaica after two legs in the women's 4x400m relay before A'Keyla Mitchell's 51.23 split on third leg gave the American quartet the slimmest lead possible. Matching the form she showed in helping her country to gold in the mixed 4x400m relay, Jaide Stepter blazed a 50.16 anchor to stop the clock at 3:23.54, a meet record by more than a second. The men's 4x400m relay wasn't as close, as Quincy Hall and Ismail Turner established a two-second lead through the first two circuits of the oval, setting up easy runs for Khallifah Rosser and Bryce Deadmon. Rosser clocked 45.09 on the third leg and Deadmon anchored the squad home in 45.44 to win by more than three seconds in 3:01.79. Javianne Oliver, Teahna Daniels, Morolake Akinosun and 100m silver medalist Celera Barnes teamed up to dominate the women's 4x100m relay, winning by almost a second in 42.35, while the men's foursome of Lawrence Johnson, Brandon Carnes, Isiah Young and Kyree King put more than a half-second margin on silver medalists Trinidad with a 38.29 gold medal performance. World Championships silver medalist Kara Winger (Colorado Springs, CO/USATF New York) only needed one big throw in the women's javelin, and her gold medal effort came in round two, sailing out to a season best and meet record 64.68m/212-2, adding more than 14 feet to her own NACAC meet record that was set in 2015. Silver went to Ariana Ince (Chula Vista, CA/USATF San Diego-Imperial) with her opening throw of 59.69m/195-10. A Canadian duo of Robert Heppenstall and Charles Philibert-Thiboutot set a torrid early pace in the men's 1,500m, and after Heppenstall faded, Philibert-Thiboutot kept pushing the pace as he was chased by Eric Holt (Patterson, NY/USATF New York), Josh Thompson (Hillsboro, OR/USATF Oregon) and Johnny Gregorek(Somerville, MA/USATF New York). The Canadian continued to lead with less than 200m remaining, but Holt pushed past him down the final straight and took gold in a meet record 3:37.62, with Thompson sprinting through for silver in 3:37.88. Gregorek was just off the podium in fourth with a 3:38.04 clocking and the top six finishers were all under the previous meet record. American record holder Evan Jager went to the early lead in the men's 3,000m steeplechase and was never in danger of losing, cruising to gold in a meet record 8:22.55. American teammate Duncan Hamilton took silver in 8:31.19, with Anthony Rotich fourth in 8:33.67. 2019 World Championships silver medalist Brittany Brown (Fort Worth, TX/USATF Iowa) ran a superb curve in the women's 200m and held off a challenge from Tynia Gaither of the Bahamas to take gold in a meet record 22.35. A’keyla Mitchell (Fayetteville, AR/USATF Arkansas) finished well to earn bronze in 22.53. Content to tuck into the middle of the pack through the first two laps of the women's 1,500m, Heather MacLean (Brighton, MA/USATF New England) and Helen Schlachtenhaufen (Cambridge, MA/USATF New England) moved quickly to the lead with just less than two to go. Adelle Tracey of Jamaica eased past Schlachtenhaufen into second with 500m left as MacLean stretched her lead with every stride, and MacLean ran away with gold in a meet record 4:04.53. Schlachtenhaufen earned bronze in 4:10.43. Will Williams (Jonesboro, AR/USATF Arkansas) scored an upset win over 2019 world champion Tajay Gayle of Jamaica in the men's long jump, spanning 7.89m/25-10.75 in round two and matching that in the fifth round. Four of Williams' five legal jumps were good enough to win. Rayvon Gray (Baton Rouge, LA/USATF Southern) was ninth with a best of 7.21m/23-8. Running side-by-side with defending champion Kyron McMaster of the British Virgin Islands off the eighth hurdle, Khalifah Rosser (Fort Worth, TX/USATF Southwestern) yielded some ground over the final two barriers but finished with silver in a lifetime best 47.59. Just off his lifetime best, CJ Allen (Marietta, GA/USATF Georgia) took bronze in 48.23. McMaster broke his own meet record with a 47.34 for gold. Jamaica's Andrew Hudson stormed off the curve in the men's 200m with a one stride lead and maintained his lead through the line to set a meet record with a lifetime best of 19.87. Already a silver medalist in the 100m, Kyree King (Ontario, CA/USATF Southern California) zipped to a lifetime best of 20.00 for silver, with Josephus Lyles (Clermont, FL/USATF Florida) claiming bronze in 20.18. Sarah Mitton of Canada won the women's shot put with a big meet record of 20.15m/66-1.5, and Jessica Woodard (Mesa AZ, USATF Arizona) and Jessica Ramsey (Memphis, TN/USATF Tennessee) also surpassed the old meet record to take silver and bronze. Woodard had her best of 18.82m/61-9 on her final throw, while Ramsey recorded a best of 18.74m/61-5.75. Dominica's Thea LaFond took top honors in the women's triple jump on her final attempt, going out to 14.49m/47-6.5 to pass Keturah Orji (Atlanta, GA/USATF Georgia), who had to settle for silver with her 14.32m/46-11.75 leap in round two. Arianna Fisher (Columbia, MO/USATF Missouri Valley) was fifth at 12.96m/42-6.25. Cassandra Tate (Baton Rouge, LA/USATF Southern) was third coming off the turn into the homestretch in the women's 400m hurdles and she held that position to claim bronze in 55.62. Deonca Bookman (Coppell, TX/USATF Southwestern) was fifth in 57.30. Going over 5.05m/16-6.75 on his second attempt, Luke Winder (Oak Park, IL/USATF Illinois) took silver in the men's pole vault. Andrew Irwin (Mount Ida, AR/USATF Arkansas) did not clear his opening height. In the men's discus, Andrew Evans (Portage, MI/USATF Kentucky) was fourth with a best of 61.09m/200-5 and Dallin Shurts (Banks, OR/USATF Oregon) was fifth at 56.36m/184-11. Results can be found here.
