Cat Osterman dominated as the United States began its quest to regain the Olympic softball gold medal, 13 years after she lost the championship game, pitching one-hit ball over six innings and striking out nine to beat Italy 2-0 Wednesday. Michelle Moultrie singled in a run in the fourth inning for the top-ranked U.S., which lost the title to Japan 3-1 at the 2008 Beijing Games. Janie Reed, the wife of Los Angeles Dodgers reliever Jake Reed, added a sacrifice fly.
