Michael Phelps Shirtless, Swimming & Placing Second (PHOTOS)

Michael Phelps is gearing up for a weekend showdown with Paul Biedermann at the World Cup in Berlin. Biedermann beat Phelps in the 200 freestyle in August.

Earlier this week Phelps placed second at the Short Course World Championships in the 200 IM in Stockholm and didn't even final in other events.

Phelps wore the old style bathing suit, just shorts, about to become regulation again. No more full body speed suits, as they've been banned starting next year.

Below are a few pics from the meet, including his face when he lost.
