ESPN — LONDON — Michael Phelps barely qualified in the 400-meter individual medley, Olympic champion Park Tae-hwan was disqualified and world record-holder Paul Biedermann failed to make the final in a surprising first day of swimming at the London Games on Saturday.

Phelps’ slow preliminary time was the biggest shocker of all. The 14-time gold medalist squeaked into the last spot in the eight-man final by seven-hundredths of a second, saying, “That one didn’t feel too good.”

Queen Elizabeth appeared briefly at the Aquatics Centre, but the biggest buzz involved the big names who struggled.
