CALI, Colombia -- On the second night of World Youth Championships at Estadio Olimpico Pascual Guerrero, Candace Hill proved she is the fastest youth in the world, and Team USA brought in four medals, including a gold, two silvers and a bronze to remain atop the medal table with five pieces of hardware on Thursday. 
 
The highly anticipated 100m final lived up to its billing as Hill (Stockbridge, Georgia) ran to a stellar 11.08 to reset her own Championships record posted earlier in the day and lead a 1-3 U.S. finish in the women’s 100. Jayla Kirkland (Birmingham, Alabama) also had the best run of her life, claiming the bronze in 11.41 and marking the fifth time Team USA has won multiple medals in the final of the WYC 100.
 
In the second semi, Hill posted 11.16 to first break the meet record, which Khalifa St. Fort of Trinidad set at 11.24 in the first semifinal. The previous record had stood for 12 years.
 
Participating in the first ever javelin-shot put double at any level of international competition, Sophia Rivera (Brentwood, Missouri) led the field with her opening shot put of 16.97m/55-8.25. Nickolette Dunbar (Whippany, New Jersey) was not far behind with a toss of 16.60m/54-5.5.
 
Germany’s Julia Ritter threw 17.27m/56-8 to take the lead, but that was short lived as Rivera was next in line and threw 17.66m/57-11.25 to regain the advantage. Dunbar improved to 16.80m/55-1.5 in round three and ended up sixth. Rivera’s best throw came on her final attempt as she launched the ball 17.93m/58-10 to take silver and match the best finish ever by a U.S. thrower in the event.
 
Brittley Humphrey (Birmingham, Alabama) smashed her lifetime best with a 13.22 in the women’s 100mH to take silver, the 12th medal Team USA has won in this event since the WYC started in 1999. Alexis Duncan (Lancaster, Texas), who tied the U.S. Youth record in the semifinal, faltered in the final and ended up seventh in 13.56.
 
Duncan went sub-13 to win the third semi, finishing at 12.95 to equal the U.S. Youth Record and set her second world youth-leading mark for 2015 in as many days. Duncan was .01 seconds off the all-time world youth best set by Yanique Thompson of Jamaica in Donetsk, Ukraine, at the World Youth Championships in 2013.
 
Decathlete George Patrick (Brentwood, Tennessee) continued his personal best streak, clearing 4.20m/13-9.25 in pole vault. He had his first down event of the competition in the javelin, recording a best of 42.64m/136-11 before two fouls and holding in fourth place heading into the 1500m, at 210 points out of third and with 159 points ahead of his PR pace from the World Youth Trials in Lisle, Illinois. Patrick responded with a gutsy 4:55.20 in the 1500 to total 7,493 and finish fourth with a U.S. Youth record. He also tied the best finish ever by a Team USA multi-eventer at the WYC, matching Curtis Beach’s placing in the octathlon in 2007.
 
Rivera had a best of 50.85m/166-10 in the third round of the javelin to place eighth. She passed on her final two attempts as she was battling for a medal in the shot. Katelyn Gochenour’s (Logan, Iowa) 45.88m/150-6 in the third round put her in 12th place.
