Box Score

LOS ANGELES -- Brian Mundell homered and had four RBIs to lead No. 2 seed Cal Poly to a 9-2 victory -- its first in the NCAA tournament -- against San Diego in an opening-round game of the Los Angeles regional Friday.

Cal Poly (40-17) broke the game open with six runs in the sixth inning, with Mundell and Jimmy Allen each hitting two-run singles. The Mustangs lost twice in their only other regional appearance in 2009.

Joey Wagman (13-3) allowed six hits in eight innings for the win.

''I tried to stick to what I've done all year,'' said Wagman, who broke the school's single-season record for wins. ''I tried to make this game seem like it's just another game, even though it means a little more.

''It's surreal. I wouldn't be here without my teammates.''

Mundell gave the Mustangs a 1-0 lead with a solo homer -- his 11th -- in the first inning. He added a sacrifice fly RBI in the fifth. Allen had four hits for Cal Poly, which reached 40 wins for the third time.

''It's a great way to start off a region,'' Cal Poly coach Larry Lee said. ''Joey has been our Friday guy all season. He has what it takes and wants to be out there at the most important times. So far, so good.''

PJ Conlon (9-1) took the loss. Connor Joe and Austin Green each had two hits for San Diego (35-24).

''I struggled with my command,'' Conlon said, ''and they put the barrel on it.''

The Toreros will play the loser of Friday night's UCLA/San Diego State game Saturday in an elimination game.

''You have to give Cal Poly credit,'' Toreros coach Rich Hill said. ''They are the best team we played this season. Wagman is a big-time performer. This is just a little hiccup. We'll play better tomorrow.''
