STOCKHOLM, Sweden -- Peter Marshall of the United States has done it again, this time breaking the short-course record in the 50-meter backstroke at a World Cup meet in Sweden.
Therese Alshammar of Sweden also set a record in the women's 50-meter butterfly in 25.31 seconds, topping the 25.32 by Australia's Felicity Galvez.
Marshall won the 50 backstroke in 23.05 seconds Wednesday, beating Australian Robert Hurley's mark of 23.24. Another American, Randall Bal, also went under Hurley's time for second place at 23.07.
"I have never had multiple world records in a meet so this is great," Marshall told Swedish television.
After watching a replay of his race, Marshall said: "I had a couple of things to brush up on so maybe I can do it again in the next meet. Who knows?"
On Tuesday, Marshall regained the 100-meter backstroke record in 49.94 seconds, breaking countryman Ryan Lochte's 2006 time of 49.99. Lochte took the record from Marshall.
