SAN LUIS OBISPO, Calif. -- Highlighed by a four-run second inning, stellar pitching from seniors Kyle Porter and Trevor Hildenberger, and an inside-the-park two-run homer by freshman left fielder Aaron Knapp, California upended No. 6 Cal Poly 8-3 on Saturday night.

With the win, the Golden Bears (11-10) snapped Cal Poly's 18-game home winning streak and the Mustangs suffered only their fourth loss of the season.

Porter improved his record to 3-1 by throwing 5.1 innings with five hits, three runs, no walks and four strikeouts. Hildenberger tallied his fifth save of the season by going the final 3.2 innings with one hit, no walks and four strikeouts.

Knapp, whose brother, Andrew, was standout catcher for Cal and a second-round draft pick of the Philadelphia Phillies in 2013, hit his inside-the-park homer in the eighth inning.

"This was a really good win for our team," Bear coach David Esquer said. "We have been struggling to score runs and today we came through with some big hits. Kyle Porter gave us a solid start and Trevor Hildenberger was outstanding out of the bullpen."
