Michael Phelps won two more races at the Minneapolis Grand Prix and 44-year-old Dara Torres finished third in her only event of the weekend Saturday night.
Phelps won the 200-meter butterfly in 1 minute, 56.12 seconds and added his fourth top finish in four chances by winning the 100 backstroke in 53.71. Six-time Olympic medalist Ryan Lochte finished fourth in the 100 backstroke with a time of 55.80.
Phelps won the 200 freestyle and 100 butterfly Friday as part of the three-day competition at the University of Minnesota.
Torres tied for third in the 50 freestyle, touching the wall in 25.30. Amanda Weir won in 25.04. Jessica Hardy was second in 25.10, and Kara Lynn Joyce tied Torres for third.
Torres is trying to qualify for her sixth Olympics.
Swimming in the same event as Torres, 16-year-old Missy Franklin finished sixth in 25.59. Franklin was the women's swimmer of the meet in Minnesota last year and won the overall Grand Prix series title.
Franklin won the women's 100 backstroke at 59.69.
Allison Schmitt won her second event of the competition, taking the 400 freestyle in 4:07.78. Schmitt, an Olympian in 2008, won the 200 freestyle Friday.
The Minneapolis Grand Prix is the first of seven stops this season on USA Swimming's Grand Prix series and is another step closer to the 2012 U.S. Olympic Trials in Omaha, Neb., and the 2012 London Games.
The top swimmer in the Grand Prix series will receive $20,000, to be awarded at the final event in June in Santa Clara, Calif.
