Jamaicans Dejanea Oakley, Shenese Walker and Shantae Foreman picked up big wins on Saturday's final day of competition at the NCAA Outdoor Track and Field Championships at Hayward Field, Eugene, Oregon. Leading the way was Oakley of the University of Georgia who remained unbeaten in the 400 metres this season. She clocked a personal best 48.79 seconds to improve on her previous best and world-leading mark of 48.92. The mark was also a facility, collegiate-leading, meet and championships record for the former Clarendon College standout who broke the previous collegiate best of 48.89 held by another Jamaican, Nickisha Pryce, in 2024.Oakley, who went into the final as the overwhelming favourite, did not have things her own way, however, as she was pushed by Madison Whyte of the University of South Carolina. Both Oakley and Whyte came off the final curve locked together before Oakley found extra in the final 20 metres for the win. Whyte was second in a personal best 48.97 and moved to world number two.According to Oakley, it was all about her confidence and patience."It was the confidence from my training, as I was told to go out and get the Championships record and there was never a doubt for me, as I was supported by my coaches, family and teammates. I never panicked, as I knew the best part of my race is in the latter stages," said Oakley. Walker, representing Florida State University, scored a massive win in the 100m. She upstaged Adaejah Hodge of Georgia, the big favourite who posted a collegiate record and world-leading 10.63 seconds in the semi-finals.Walker, the fastest Jamaican woman in the event this season and second behind Hodge in the world rankings with 10.80, got a perfect start and maintained her form well to win in 10.88. Hodge was second in 10.93 and Shawnti Jackson of Louisiana State University third in 11.01. Gabrielle Matthews of the University of Florida was sixth in 11.12.Despite going into the final as the underdog, Walker was always confident."For me, I was not awed by the situation as my experience paid off after being second in 2024 and sixth last year. I am very confident. I don't really watch my competitors. Staying focused and executing was the easiest thing I could have done. I am a senior, so the chemistry took a while," stated the former Hydel High and St Jago High athlete.Foreman of Clemson, after her second-place finish two days earlier in the long jump, went one place better in the triple jump after winning the event with a personal best and collegiate-leading mark of 14.24m. The former St Jago and Excelsior High jumper led for most of the competition but was relegated to second in the fifth round by Sharifa Davronova of the University of Oregon. However, Foreman kept her cool and, with her final attempt, pulled off the victory.Two other Jamaicans were in field events action on the day. Abigail Martin, competing for Texas A&M, finished eighth in the discus with a mark of 56.15m while Annishka McDonald, representing West Virginia, was 13th in the high jump after clearing 1.79m. Sprint hurdler Janela Spencer, representing Ohio State University, was third in the women's 100m hurdles in 12.79 seconds while Toniean Forbes of Texas Tech was fourth in 12.80.Following her disappointment in the 100m, Hodge returned to post a personal best 21.68 seconds to win the 200m. She erased the former collegiate best of 21.80 held by Abby Steiner of Kentucky. It was also the fastest time in the world this season. Jackson was third in a personal best 22.12 while Matthews ended fourth in 22.79.Another new collegiate best came in the women's 800m as Gambia's Sanu Jallow, representing the University of Arkansas, broke Athing Mu's mark of 1:57.70 in winning the event in a personal best 1:56.85.
