It was a pretty disheartening opening day, overall, for the Americans.
Ryan Lochte looked great, swimming his best time ever to win the 400 IM. The other guy (yes, Michael Phelps was just referred to as "the other guy") took fourth and looked awful all the way through.
Panic time? Looks like it.
Dana Vollmer is the star of the day for the U.S., setting an Olympic and textile (non-synthetic suit) record in the 100 butterfly, with the final coming up tomorrow.
Missy Franklin gave the 4x100 freestyle team a lead in her first leg, and the Americans held it until the halfway point but faded back to bronze.
The overall performance of the day came from 16-year-old Ye Shiwen of China, setting a world record (4:28.43) to win the women's 400 IM.
There's a lot more to come. Could Phelps be completely melting down? Is Missy going to dominate? Will Lochte be the star of the Olympics? We'll see...
