Literally, a photo finish

Sports Illustrated has a series of photos showing just how close Milorad Cavic came to upsetting Michael Phelps in the 100-meter butterfly yesterday. It's easy to see why, to some outside the pool, it looked like some conspiracy that Phelps won. He was so far behind before that final half-stroke that chopped the wall that it looked like an error when they superimposed that #1 graphic in his lane on TV.

I don't understand the advantages of wearing the high neck Speedo LZR Racer suit versus just the legskin, but I wonder why Phelps only wore the legskin for this swim, and whether that would have made a difference. Cavic wore the high neck bodyskin.
