Clayton Kershaw leaves with injury vs. Giants - MLB.com

SAN FRANCISCO -- Dodgers left-hander Clayton Kershaw exited with low back pain before the bottom of the fifth inning of Thursday’s 5-3 win over the Giants at Oracle Park. .

As he warmed up to pitch the fifth, Kershaw felt his back tighten up after his penultimate warmup throw.

If Kershaw is forced to miss time, it will be another big blow for the Dodgers.

When healthy, Kershaw has been one of the club’s best pitchers, posting a 2.64 ERA over 15 starts.

Dustin May, who pitched four innings with Triple-A Oklahoma City during his rehab assignment on Wednesday, will need at least one more outing in the Minors before being a candidate to replace any starts Kershaw might miss

Seeing Kershaw leave the game was about the only thing that went wrong for the Dodgers during their 7-1 road trip against the Rockies and Giants
