COLUMBUS, Ohio (AP) — For Michael Phelps the maxim is: You snooze, you win.

Phelps, winner of six gold medals and two bronzes at the 2004 Olympics in Athens, slept through a preliminary heat for the 400-meter free earlier in the day but came back to win the 400 individual medley on Saturday night at the Columbus Grand Prix.

Phelps breezed to his win in the 400 IM in 4 minutes, 13.73 seconds, a full 8 seconds faster than he went in the prelim and over 3 seconds faster than runner-up Erik Vendt.
