Allison Schmitt has added another race to her growing Olympic schedule, winning the 200-meter freestyle Thursday night at the U.S. Swimming Trials at CenturyLink Center Omaha.

Schmitt broke her own American record with a time of 1 minute, 54.40 seconds, the best in the world this year. Already the 400 free winner in Omaha, she set the previous national record in the 2009 world championships.

Missy Franklin claimed the second 200 spot on the team for London, rallying from fifth place at the first turn to take the runner-up spot in 1:56.79.

Dana Vollmer and Lauren Perdue finished third and fourth, assuring themselves of being in the pool for the 800 free relay. Shannon Vreeland (fifth) and Alyssa Anderson (sixth) also are likely to be taken to London as potential relay swimmers.

Michael Phelps stayed on course to swim eight events at the London Olympics with a dominating win in the 200-meter butterfly.

He trailed Davis Tarwater at the first and second turns, but there was never any doubt that Phelps would pull ahead in his signature stroke. He surged ahead on the third leg and was a body-length ahead of the field when he touched in 1 minute, 53.65 seconds.

The real race was for second place and a spot on the Olympic team. Tyler Clary, who lost out to Phelps in the 400 individual medley, rallied from behind for a time of 1:55.12. Clary pumped his right fist and pounded the water when he saw the scoreboard.
