FULLERTON, Calif. (AP) — Eric Filia broke a 10th-inning tie with an RBI single — his fourth hit of the game — and Pat Valaika drove in another run with a sacrifice fly in UCLA's 5-3 victory over Cal State Fullerton on Friday night in Game 1 of the best-of-three NCAA super regional series.

"He (JD Davis) threw me two high fastballs and I knew he was coming with a curve ball," Filia said about his one-out hit. "He left it up and in hit into right field."

Pac-12 pitcher of the year David Berg (7-0) struck out Davis and Michael Lorenzen with two runners on in the bottom of the inning for the Bruins (43-17).

"I froze him (Lorenzen) with a two-seam slider," Berg said about the game-ending pitch.

Davis (1-2) took the loss in relief for Fullerton (51-9).

Game 2 is Saturday, with UCLA trying to advance to the College World Series for the fifth time.

"It was very competitive night with two of the best pitchers in the country," UCLA coach John Savage said. "You have two teams who have won over 90 games. We battled and competed. We scrapped and scored a couple runs early.

"Our bullpen did its job, but this series is far from over. You don't win 50 games (Fullerton) and go away. ... We played close games all season. We have something like 14-15 one- run games. We're used to it. It's our style of baseball."

Fullerton scored twice in the eighth inning to tie it at 3. After Richy Pedroza and Carlos Lopez walked to start the inning and Matt Chapman moved them up with a sacrifice, Davis had an RBI infield groundout and Lorenzen followed with a run-scoring infield single.

UCLA took advantage of a Fullerton miscue in the third inning to open the scoring. Shane Zeile doubled leading off, moved to third on a sacrifice and scored on first baseman Carlos Lopez's fielding error.

Pat Gallagher's RBI single in the fourth made it 2-0, and Anthony Hutting cut it to 2-1 with an RBI single in the bottom of the inning. Brian Carroll scored for UCLA on an infield groundout in the eighth.

Fullerton lost for only the fifth time in 30 home games this season.

"We lost and we didn't catch the ball very good," Titans coach Rich Vanderhook said. "We gave them too much and when you do that this time of year you lose. We had opportunities to score against Berg. We grinded it, but we had some frustrating at-bats in the game. We didn't do it and we paid the price."
