Olympic trials 2012: Michael Phelps secures 200m butterfly berth on US swimming team "That was the best my stroke's felt throughout the meet," said Phelps after his 200 fly victory. In all I'm pleased, but I think I need to go faster if I want to win that at the Olympics. I was just thinking about it today, this is my fourth Olympic Games in this event, so it's special to me ... I have a couple of weeks to perfect some things that I'm going to need if I want to end with a good one. Behind Phelps in the 200m fly Tyler Clary won a furious race for second place - and the other London Games berth on offer - rallying to claim second in 1min 55.12sec ahead of Bobby Bollier and Davis Tarwater. Tyler Clary, who missed out on a trip to London as he finished third in the 400m medley behind Ryan Lochte and Phelps, pounded the water in celebration when he saw he was headed to the Olympics. "It was amazing," Clary said. I can't even put into words how the end of that race felt, not only the pain in the last 20 meters but just the complete and total turnaround. I'm on cloud nine right now. Allison Schmitt, who trains with Phelps and coach Bob Bowman at North Baltimore, added another race to her Olympic programme, winning the 200m freestyle in 1min 54.50sec, the fastest in the world this year, improving on the 1min 54.66sec posted by France's Camille Muffat. I didn't feel like I was on my (American) record pace, but I could hear the crowd. I was pretty excited before I even looked up and saw the time," said Schmitt, who won the 400m free earlier this week. In the day's other final, Caitlin Leverenz won the women's 200m individual medley in 2min 10.22sec to give herself a shot at a medley double in London. Ariana Kukors, who set the world record in the event in 2009, before hi-tech bodysuits were banned, finished second to seize an Olympic berth. Nathan Adrian led the way into the final of the men's 100m freestyle with a semi-final time of 48.33sec which put him among the top 10 performers this year. Lochte, pursuing his own multi-medal programme in London, was equal fifth-fastest in the semis but scratched from Friday's final to focus on the 200m backstroke - which he won in Beijing - and the 200m medley - which promises another showdown with Phelps.
