COLUMBUS, Ohio - Ohio State right-hander Greg Prenger pitched a perfect game Wednesday night, retiring all 21 batters he faced in the Buckeyes' 2-0 victory over Oakland.

The Ohio State sports information office said it's believed to be the first perfect game in the school's 120 years of playing baseball.

Pitching the second game of a doubleheader, Prenger struck out six and got seven batters out on fly balls or popups. The final out came on a popup by Oakland's Jeff Hall.

"Nothing compares to this experience," said Prenger, a 6-foot-1 senior from Harpster, Ohio. He missed all of last season after having surgery on his right shoulder in the summer of 2001. "I didn't even realize what was going on until about the fifth inning. This is an incredible experience."

It was the eighth no-hitter in Ohio State history and the first since 1998.
