Marchand shattered Ryan Lochte's 200-meter individual medley world record on Wednesday. Swimming at the world championships in Singapore, Marchand swam a 1:52.61. Lochte's record had stood since 2011 at 1:54.00.

Leon Marchand, the French swimming sensation who claimed four Olympic gold medals in Paris last year, delivered a brilliant performance in Singapore.

Marchand, who won four golds in Paris, lowered Ryan Lochte's 14-year-old mark by more than 1.3 seconds in Wednesday's semifinals.
