American Gretchen Walsh capped a record-setting week at the short course swimming World Cup event in Carmel, Indiana, with a dominant triumph in the 100m butterfly on Sunday.

Walsh, who lowered her own world record in the 50m fly on Saturday, couldn't top her 100m fly world mark, but her winning time of 53.69sec was more than a second-faster than runner-up Alexandria Perkins, who clocked an Australian record of 54.93.
