Matt Cain scratched from Monday start vs. Cubs - MLB

Giants right-hander Matt Cain had to cut a bullpen session short on Saturday afternoon due to lingering discomfort in his right hamstring and now Andrew Baggarly of CSNBayArea.com reports that he has been scratched from his next turn in the San Francisco starting rotation, Monday against the Cubs. Yusmeiro Petit will make the start instead.

Cain suffered a Grade 1 right hamstring strain three innings into his start last Wednesday against the Rockies. The Giants are optimistic that he will only need to miss one outing, so they’re keeping him off the disabled list for now.

Cain has a 3.66 ERA, 1.22 WHIP, and 39 strikeouts in 46 2/3 innings this year for first-place San Francisco.

OAKLAND, Calif. – Major League Baseball is looking into a video circulating on social media that appears to show Los Angeles Angels third baseman Anthony Rendon grab a fan by the shirt through the bleacher guardrails after Thursday night’s game in Oakland, a league spokesperson said Friday.

Rendon looks to have grabbed the fan’s shirt near his chest through the bars of the railing and exchanged words with him before appearing to take a swipe at the bill of the man’s ballcap and walking into the tunnel.

Angels spokesman Adam Chodzko says the team has no comment. The Angels do not play Friday, but the club expects Rendon to address the video Saturday in the clubhouse before the game against the Oakland Athletics in Oakland.

The video shows the fan, dressed in A’s colors, approach the railing as Rendon turns toward him from the tunnel walkway below. Rendon then appears to grab the man’s shirt and ask him what he just said, accusing the fan of calling him a derogatory term before swiping at his ballcap.

The A’s won the game 2-1.
