For a day, the most popular U.S. swimmer in Beijing wasn’t Michael Phelps. Jason Lezak is the reason Phelps’ goal of breaking Mark Spitz’s record for the most gold medals in one Olympics is still possible. Lezak is the one who anchored that incredible comeback in the 4X100 freestyle relay Monday morning, overcoming a deficit over the final 50 meters to clinch the victory.

Lezak rarely has done things on his own in the pool. He has won 15 medals in world and Olympic competitions. All have come as part of relay teams.
