EUGENE, Ore. (AP) — Sydney McLaughlin looked to her left and saw the numbers “51.90.” Her first thought: “Oh my gosh!” Now, at long last, the 400-meter hurdles world record belongs to her. On Sunday night at U.S. Olympic track trials, McLaughlin finally outraced Dalilah Muhammad to earn the victory, and the record, that Muhammad kept grabbing whenever they met. McLaughlin’s 51.90 was good enough to beat Muhammad by 0.52 seconds. It shattered Muhammad’s old world record by 0.26.
