OMAHA, Neb. — There will be a familiarity between UC Irvine and Cal State-Fullerton when they faceoff in an elimination game.

"One of the two of us is going home and I haven't mapped it out yet," said Fullerton coach George Horton, who will face Irvine coach Dave Serrano, Horton's pitching coach in Fullerton for eight seasons. "One of us has to fly the Big West flag but whoever gets it done will represent us well."

Oregon State (45-18) and Arizona State (49-13) will face off for the fourth time this season on Monday, marking the first time since 1998 two Pac-10 teams met in Omaha. The winner will need to win one of its next two games to go on to the championship round. The loser will face the Irvine-Fullerton winner.

The Big West matchup between the Titans (38-24) and Anteaters (45-16-1) is a first for the conference on college baseball's national stage, as 24-year friends Horton and Serrano will try to send each other home.

Louisville and Rice continued scoring ad nauseam Sunday, as Louisville eliminated Mississippi State with a 12-4 win and Rice took firm control of Bracket 1 by beating North Carolina, 14-4.

The teams became just the fifth and sixth in CWS history to score ten runs in each of their first two games in Omaha.

Louisville (46-23) will face North Carolina (54-14) on Tuesday and the winner will play Rice (56-12) Wednesday for a berth in the championship round. The loser is out.

"We've always said you have to swing your way to Omaha," Louisville coach Dan McDonnell said. "Obviously, you have to pitch and defend. Everything counts. But you have to score runs."

Louisville's sluggers overshadowed a strong effort from freshman Justin Marks (9-2), who held Mississippi State (38-22) to two singles before he took a sharp hit to his left leg in the sixth.
