WTF!? USA loses to Korea?

Team USA was upset yesterday by South Korea in their first game of the Olympics. South Korea scored 2 runs in the ninth to win 8 to 7. The Americans need to really step it up a notch because their schedule gets even tougher, with Cuba and Japan on the horizon. Hopefully this was a HUGE wakeup call for the U.S., because this is their last chance for an Olympic medal ever, unless the IOC changes their mind.
