OMAHA, Neb. (AP) _ Fullerton State won its two national titles at the College World Series when it had to battle back through the losers bracket. Lousiana State did the same thing last year.

Now, both teams once again have their backs to the wall.

Fullerton State, the No. 7 seed, fell to No. 2 Georgia Tech 2-0 on Brad Rigby's three-hitter. LSU, the No. 3 seed, was set back by No. 6 Florida State's six-run, sixth-inning outburst in a 6-3 loss in Friday's opening round.

Florida State (53-20) meets Atlantic Coast Conference foe Georgia Tech (48-16) Sunday afternoon. Tech won two of three regular-season meetings.

Sunday evening, Fullerton State (45-15) faces off with LSU (46-19) in an elimination game.

''We're going to come back,'' said Fullerton State center fielder Dante Powell. ''At Cal State-Fullerton, we can never do anything the easy way.''

Rigby (14-4) didn't make it easy in the tournament opener when he collected 10 strikeouts in his complete-game win.

''The whole key for us was Brad throwing the ball well and keeping us in the ball game,'' said Georgia Tech coach Danny Hall, whose team was in its first CWS game. ''We didn't play good defense, but I can't emphasize enough how Brad pitched us out of things so well.''

Rigby overcame three errors and allowed only one runner to reach third base. Fullerton State hitters managed to get just four balls to the outfield.

His outing overshadowed a five-hit performance over 7 1-3 innings by Titan starter Mike Parisi (11-4).

''I think the game centered around pitching on both sides,'' said Fullerton State coach Augie Garrido. ''Since the margin of difference was slim, each opportunity that wasn't capitalized on was to our demise.''

In the second game, the sixth inning was the demise of LSU.

Florida State used Steve Nedeau's leadoff triple to break the spell of LSU starter Scott Schultz (12-2), who opened with four perfect innings, then gave up a double to Randy Hodges in the fifth.

Nedeau started a parade of 11 FSU batters to the plate in the sixth. He scored on Jack Niles' single. Mike Martin Jr. singled in another and Hodges brought in another run when his grounder was misplayed by a slipping Jason Williams at third for LSU.

Link Jarrett doubled in the fourth run and Scott Zech capped the scoring with a two-run single to back the seven-hit pitching of Paul Wilson (12-6). Wilson, the first player taken in Thursday's major league draft, had a bumpy start, giving up six hits in the first four innings, including Todd Walker's 18th homer of the year and an RBI double to Brad Wilson in the fourth.

Walker, the 1993 College World Series most valuable player, brought in LSU's final run with a sacrifice fly in the seventh.

''It was a college baseball team facing a big league pitcher,'' said Walker in reference to the hard-throwing Paul Wilson.

''Everything happens for a reason, whatever that reason is,'' said LSU's Russ Johnson. ''We were facing the No. 1 (draft) pick in the country and I think they accept that. They ain't gonna face another one like him so that's out of the way. Whoever else faces us, unless they're throwing 96 (mph)... They'll probably be throwing 90 and get lit up.''

''I'm not disappointed at all we got beat,'' Walker said. ''We got beat. We didn't beat ourselves. We got a bad draw. We had to face Paul Wilson. I still think we're a good ball club. I don't think anybody else would have done much better against Paul the way he was pitching tonight.''
