13 Can't Miss USA Athletes At U20s, Plus 6 More Worldwide

Team USA 


Anna Hall

Event: Heptathlon

School: Valor Christian (CO) junior

Breakdown: The American record holder with 5,798 points, Hall still isn't guaranteed a medal here. She enters ranked eighth overall and has the 10th best mark worldwide across U20 performances. But the Valor Christian (CO) athlete has put down two impressive efforts over the last month--including her win at the USA Junior Championships with 5,660 points--and a half and certainly will be in contention for a big place here.
