EAST MEADOW, N.Y. – Ian Crocker closed out his career at Texas by setting a world record in the 100-meter butterfly at the NCAA men’s swimming and diving championships Friday, winning the event for the fourth straight year.

Teammate Brendan Hansen also completed a four-year sweep in the 100 breaststroke, prevailing in 58.19 seconds at Nassau County Aquatic Center. The swimmers were competing in a 25-meter pool, as opposed to 50-meter lengths they would swim in Olympic competition.

Crocker, of Portland, won in 49.07 in seconds, and the duo became the ninth and 10th swimmers to win four straight events in NCAA championships history. Crocker is only the third to win the butterfly four times. Mark Spitz of Indiana and Pablo Morales of Stanford also accomplished the feat.

Hansen is the second to sweep the breaststroke over four years, joining Steve Lundquist of SMU.
