Michael Phelps wasn't as generous this time around.
Phelps, who yielded his spot on the U.S. gold medal 400-meter medley relay to Ian Crocker at the Olympic Games last summer, caught his longtime friend and rival at the finish and won the 100 butterfly at the U.S. trials in Indianapolis for the world championships in July.
It was the third victory of the meet for Phelps, who trailed Crocker by more than a half-second at the turn but pulled ahead to win in 51.34 seconds. Crocker, who holds the world record of 50.76, finished at 51.45.
"I always feel I have to be at a certain place when I race Ian," Phelps said. "I know he has a faster first 50 than I do, so I always feel like I should be within striking distance, within a half a body length of him. I saw him coming off the wall and I just tried to do everything I could to get home."
