Eric Harrison/Khance Meyers
Event: 200, 4x100
School: Ohio State University/Hinds Community College
Breakdown: Jamaica's Christopher Taylor, who owns the top two 200m times worldwide in the U20 ranks, opted for the 400m, which leaves Harrison as the favorite in the field after his 20.39 from the Big Ten championships in May. He's not guaranteed anything, though. Behind the Buckeye stands South Africa's Thando Dlodlo, who comes in with a best of 20.41--he's also trying to knock off Anthony Schwartz in the 100m.
Nobody should sleep on Meyers, either. The Michigan native finished his first year with Hinds Community College and won two national titles over the indoor and outdoor season, including an all conditions 20.02 in May. Before that career best, he ran a wind-legal 20.62, which is No. 15 worldwide at U20.
