US-Australia rivalry highlights 1st night in Olympic pool (Yahoo Sports)

Katie Ledecky is going for a sweep of the longer freestyle races at the Olympics, a feat unmatched since another American teenager achieved it 48 years ago. Before she tries to equal Debbie Meyers’ golden triple, Ledecky could join the U.S. 4×100-meter freestyle relay team when the eight-day swimming competition begins Saturday. If she wins her three individual events and a relay, the 19-year-old Ledecky would take four gold medals back to her Maryland home, equaling the record for a U.S. female swimmer shared by Amy Van Dyken and Missy Franklin.
