Michael Phelps will get another chance to go after Mark Spitz's Olympic record in Beijing.

Phelps locked up his eight-race schedule by winning the 100-meter butterfly at the U.S. swimming trials Saturday night, powering away on the return lap to easily beat world-record holder Ian Crocker. The winning time was 50.89 seconds, about a half-second slower than Crocker's 3-year-old mark of 50.40.

Crocker led at the flip but faded over the final 50. Still, he held on for a spot on his third Olympic team spot, finishing second in 51.62.
