Top pitching prospect Gerrit Cole had his worst start of the year Thursday night, surrendering a season-high six runs and nine hits as the UCLA baseball team dropped its series opener, 7-4, at Stanford.
Cole, known as a power pitcher with a live arm, gave up two home runs. He had only one strikeout in 6 1/3 innings.
The 20th-ranked Bruins (20-13, 9-4 Pac-10) battled back from a 3-0 deficit and Cody Regis extended his hitting streak to 14 games, but Stanford (18-12, 4-6) added a run in the sixth before chasing Cole (4-4) in the seventh.
UCLA fell into a three-way tie for second place with Arizona State and California. Oregon State, which visits Jackie Robinson Stadium next weekend, leads the way with a 9-1 conference mark.
UCLA and Stanford resume the series Friday at 5:30 p.m. PT, with Trevor Bauer (7-1, 1.47 ERA) taking the hill for the Bruins and Jordan Pries (4-3, 3.26) going for the Cardinal.
