HURDLES HIGHLIGHT LAST DAY OF U.S. CHAMPIONSHIPS

World-leading performances, sur- prise breakthroughs and even a major upset highlighted the final day of the USA track and field championships Sunday in Sacramento. Dalilah Muhammad led a scintillating 400 hurdles, Ryan

Crouser and Joe Kovacs threw haymakers at each other in the shot put and collegiate star Dae

jah Stevens upset the world leader in the women’s 200. Muhammad led three runners under 53 seconds for the first time, and six under 54 for the first time, sprinting to a personal-best and world-leading time of 52.64, ahead of Shamier Little (52.75) and Kori Carter (52.95). Muhammad, Little, Carter and Cas

sandra Tate (who has a bye into the worlds as the 2016 Diamond League champ) will represent the USA in the world championships in London in August, and it’s quite possible that 400 final won’t match this one. It included 17-year-old Sydney McLaugh

lin, who finished sixth in a world junior record 53.82.
