21-year-old Texan Cat Osterman was unhittable yesterday. In a rematch of the 2000 gold medal game, she led the U.S. to a 3-0 victory.

"Japan is a great team, obviously, being No. 2 in the world," said Osterman. "The first game, I was so excited to be out there. I was shaking, so I don't know if it was from being excited or nervous. But those two batters in that first game got me an Olympic feel, got that out of the way, and I was definitely ready to pitch today."

The team followed that win with another over China earlier today. The U.S. got another great pitching performance, this time from Lori Harrigan, who threw a one-hitter.
