Ryan Lochte faces his final and best chance at a piece of Olympic history on Friday night in Omaha.
The 12-time Olympic medalist, who turns 37 during the Tokyo Olympics on Aug. 3, would become the oldest U.S. Olympic male swimmer in history if he wins the 200m individual medley final at the U.S. Olympic Trials.
The second-place finisher will likely qualify as well, but that is not guaranteed until enough men make the team in multiple events; the U.S. Olympic pool swimming team cannot exceed 26 men.
The 200m IM is the only individual event Lochte has raced at all four of his Olympic appearances, taking two silvers and a bronze.
