New American U20 Record Christian Miller, the Creekside (FL) star senior and @ugatrack signee, clocked a new American U20 record in the 100m of 9.93 (+1.6) to win at the PURE Athletics Spring Invitational.
That passes Trayvon Bromell, who held the previous U.S. U20 record at 9.97 (+1.8). #athletics#usa#miller
