ATHENS, Georgia, July 11. THE Greatest of All Time Michael Phelps is rounding into form nicely just a month out from U.S. Nationals. Tonight, Phelps posted the second-fastest 100-meter fly in the world during the Bulldog Grand Slam.

As part of a highly anticipated showdown with SwimMAC's Ryan Lochte, Phelps crushed the competition with a 51.67. Only Viacheslav Prudnikov has been faster with a 51.60 from the Russian National Championships. Phelps had been hanging out around the 51-second stage with a 52.11 to rank 10th in the world since his comeback in April. Tonight, he demolished that effort.

Lochte, meanwhile, checked in with a second-place time of 53.08. He is ranked eighth in the world with a 51.93 from the Mesa stop of the Arena Grand Prix, but hasn't been quite the same since re-injuring his knee in Mesa. SwimMAC's Matt Josa rounded out the top three in 53.64.
