The swimming events at the 2012 Olympics got off to a surprising start on Saturday, as Ryan Lochte won the 400m Individual medley for the U.S., while Michael Phelps finished in fourth place, failing to medal. Considering this is the year Phelps was expected to extend his all-time medals lead, this Summer Games has gotten off to an inauspicious start for him.
With four medal events in the books heading into Sunday, the United States has already picked up a gold, a silver and two bronze finishes. It will be another full day of swimming events on Sunday, including plenty of heats and four more medal finals.
The heats will begin very early in the U.S., although the qualifying and medal rounds will be shown on tape delay on NBC. Qualifying heats will be shown at 11 a.m. and 1:30 p.m. in all time zones, while the four gold medal finals will be on NBC from 7 p.m. until midnight -- along with other sports -- in all time zones.
