Olympic trials 2012: Ryan Lochte beats Michael Phelps in 200m freestyle semi-final However conscious of the effort it will require to take on Phelps, Lochte then scratched from the backstroke semi-final. "I just want to get ready," said Lochte "I don't want to have to worry about swimming" an extra race. Meanwhile Brendan Hansen capped his comeback by earning another trip to the Olympics, winning the 100-metre breaststroke final. Hansen, 30, rallied down the last length to post a time of 59.68sec, to qualify for London. He was one of the world's top breaststrokers leading up to both Athens and Beijing, but has yet to win an individual gold. He now has a third chance in London. Eric Shanteau is also heading back to the Olympics and this time he doesn't have to worry about battling cancer. He finished second to Hansen, pumping his fist when his position was confirmed, slapping hands with the winner and then running across the pool deck to kiss his wife. At the trials four years ago, Shanteau beat Hansen for an individual spot on the team shortly after being diagnosed with testicular cancer. He put off treatment until after the Beijing Games and has been healthy ever since.
