OMAHA, Neb. -- Aside from one shaky inning, Mark Prior showed he was anything but a normal pitcher.

Prior struck out 13 in seven innings to help lead Southern California to an 11-5 victory over Georgia in the College World Series on Saturday.

Bulldogs hitters consistently looked overmatched, swinging through Prior's blazing fastball and freezing at the sight of his off-speed pitches.

"I felt like I had some stuff on my fastball," Prior (15-1) said. "They came out hacking in the first inning. I wouldn't say I was surprised by that, but I knew what kind of a day I was in for."

Overall, Prior lived up to his billing as the second overall pick, taken by the Chicago Cubs, in Tuesday's draft.

"I thought Mark Prior was everything he was advertised," Georgia coach Ron Polk said. "I had not seen him since his freshman year. Boy, he has a great future."

Prior had at least one strikeout in every inning, and struck out the side twice.

"Swing the bat. That's all we could do," Georgia's Jeff Keppinger said.

Prior, who walked one and allowed four runs and nine hits, has 202 strikeouts and just 18 walks in 138 2-3 innings this season.

Prior looked mortal in the fourth inning, when Georgia scored three times against the 6-foot-5 right-hander. But the Trojans (45-17) got their offense going early, and the Bulldogs (47-21) couldn't catch up.

"In the fourth inning, they got some hits," Prior said. "I wouldn't say I got hit hard, but they had some hits that found some holes."

Alberto Concepcion went 3-for-5 with two home runs and five RBI, and Bill Peavey also homered twice for Southern California, which used a season-high 18 hits and six home runs to win its seventh straight.

USC will play Miami (50-12) on Monday night, and Georgia will take on Tennessee (46-19) in the early game that day. The Hurricanes won a wild 21-13 game against the Volunteers late Saturday night.

The Trojans got on the scoreboard quickly with back-to-back homers by Concepcion and Peavey in the first off Jeremy Brown (7-4).

While Concepcion's shot barely cleared the right-field fence, there was no doubt about Peavey's homer. The 6-4, 250-pound first baseman hit a shot estimated at 440 feet that easily cleared the 26-foot high screen in straightaway center to make it 2-0.

"I think I felt that the size of the park played a little bit of a role in my second home run, but not my first one," Peavey said, drawing laughs.

"I heard that they were going to move back the fences and raise them," Polk said. "I wish they would have done that about 3½ hours ago."

USC added three runs in the second on Brian Barre's RBI single and Concepcion's two-run triple.

Brown was done after throwing 55 pitches and allowing five runs and seven hits through two innings.

Josh Self gave the Trojans a 6-0 lead with an RBI single off reliever Jody Friedman in the third.

The Bulldogs, in the College World Series for the first time since winning it in 1990, broke through against Prior in the fourth.

David Coffey hit a leadoff double, and Keppinger launched a 1-1 pitch over the left-field wall for his 17 homer of the season, and eighth in nine NCAA tournament games.

Adam Swann and Doc Brooks followed with consecutive hits. One out later, Prior was called for a balk by second base umpire Gus Rodriguez, sending Swann home and making it 6-3. But Prior settled down after that.

"I was particularly pleased with the way Mark maintained his composure," Trojans coach Mike Gillespie said. "It doesn't mean that I'm surprised by that because he has pretty much done that all season, but it was a good test for him."

USC added another run on Michael Moon's leadoff home run in the fifth off Friedman.

Keppinger's two-out RBI triple in the seventh made it 7-4, but Peavey homered in the bottom of the inning to open a four-run lead again for the Trojans.

Mark Thornhill hit an RBI double off reliever Anthony Reyes in the eighth for Georgia's final run.

Barre led off the eighth with a home run that hit off the video screen in center field, and Concepcion hit a two-run homer off Friedman to make it 11-5.

Bulldogs coach Ron Polk, who retired as coach at Mississippi State after the 1997 College World Series, led Georgia to Omaha in only his second season at the school.
