By BRENT STUBBS Senior Sports Reporter bstubbs@tribunemedia.net It was quartermiler Shaunae Miller's time to shine, stepping down to post the Carifta, Central American and Caribbean Junior Championships and the IAAF World Junior Championship marks in the 200 metres. While she is yet to run her first 400 for the year, Miller had a sensational double dip at the 9th Club Monica Track Classic at Thomas A Robinson Track and Field Stadium. She clocked 11.50 seconds in the 100 on Friday and came back on Sunday and ran 22.95 in the 200. In the process, the 17-year-old St Augustine's College senior did both the qualifying times for the Carifta Games and the Junior Central American and Caribbean Championships. But while Miller also did the IAAF World Junior Championships' qualifying time of 23.92 in the 200, she was just shy of the century mark of 11.80. "It was a good experience for me but I always thank God for allowing me to get the victories," Miller said. "The times that I ran were only because of him." Although she was surprised by the performances, Miller said her coach and father Shaun Miller has made the training sessions quite fun so she's enjoying what she's doing right now. "I'm just running these for the speed right," said Miller, whose goal is to repeat as the Worlds Junior champion in the 400 when she heads to Barcelona, Spain, in July. "I haven't had a time set yet for the 400, but a 50 would be nice." Lenece Clarke trailed Miller in the straight away race in 11.95 and Carmiesha Cox, now in his first year in the under-20 division, was the runner-up in the half-lapper in 24.12. A series of outstanding performances were turned in the two-day meet. Two came in the open men's 800 where Andre Colebrooke and Ashley Riley both produced the under-20 boys Carifta and Jr CAC qualifying performances. Competing in two separate heats in the timed final event, Colebrooke pulled away from the field and stopped the clock at 1:53.38 before Riley came behind him and out-sprinted his rivals for his second place overall in 1:54.91. They both were chasing the IAAF World Jr Championships' qualifying mark of 1:51.00. "My intent was to go out there and run hard and qualify for the World Juniors," said Colebrooke, a student of Eleuthera. "I was about two seconds off, but next week I hope to be back with the 1:51." Colebrooke, 17, said he would prefer to get a chance to compete with Riley because he believes that a head-to-head confrontation would definitely bring out the best in both of them. Riley, a 16-year-old student of CR Walker, said after watching Colebrooke in the first heat, he knew that he had to run in his heat that followed. "It was hard, but I felt good," Riley stated. "I think if we ran against each other we would run faster, but we can't always get what we want. So I have to be happy with what we have right now." Devynne Charlton once again produced the triple qualifying feat in winning the under-20 girls 100 hurdles in 14.03 and Latario Minns did the same in the under-20 boys triple jump with his winning leap of 16.32 metres or 53-feet, 6 1/2-inches. Club Monica won the meet, taking the girls' title with 225.5 and the boys with 206. While the Striders got second place in the girls with 188.5, the Road Runners were runners-up in the boys with 200.
