Cammile Adams became a first-time Olympian with a win in the 200-meter butterfly at the U.S. Swimming Trials and Nathan Adrian captured the 100-meter freestyle.
Brendan Hansen and Eric Shanteau were expected to be the top finishers in the breaststroke event and thus qualify for next month's Olympics in London. They already had claimed spots on the Olympic team earlier in the trials by finishing 1-2 in the 100-meter breaststroke.
Weltz, however, put on a late sprint and won the finals in 2:09.91, with Burckle finishing second in 2:09.97. Shanteau wound up third and Hansen fourth and neither will swim the 200-meter race in London.
Adams turned in a time of 2:06.52 to win the 200-meter butterfly with Kathleen Hersey capturing an Olympic berth with her second-place finish.
Adrian won the 100-meter freestyle in 48.10, with Cullen Jones finishing second in 48.46.
Jones swam the third leg on the wining American 400-meter freestyle relay team at the Beijing Olympics. That victory, which came by just .08 of a second over France, allowed Phelps to win one of his record eight gold medals at those Games.
Phelps and Lochte will go at it again Saturday in the 200-meter individual medley after they turned in the two fastest qualifying times Friday.
Lochte was the top qualifier in 1:55.51 and Phelps was timed in 1:56.66. They have split their two duels thus far in these trials -- Lochte winning the 400-meter individual medley and Phelps the 200-meter freestyle.
