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.

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

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.

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.
