NEW YORK — Giants RHP Matt Cain needs surgery to remove bone chips from his right elbow, which likely will end his season.
Friday, Cain played catch and is waiting to see how his arm responds before deciding when to have surgery. Manager Bruce Bochy, though, said the team let him throw just to "check off that box."
Cain, 2-7 with a 4.18 ERA, has been out since July 9.
"I've had (the chips) for 10 years," he said. "They've always been there. Now they're mad and letting me know about it."
More Giants: 2B Dan Uggla was designated for assignment a week after being called up. Uggla, who signed a minor-league deal July 21 after being released by the Braves, went 0-for-11 with six strikeouts and three errors.
Replay controversy: MLB said it got a replay call right in ruling Marlins C Jeff Mathis blocked the plate. In the eighth Thursday, the Reds' Zack Cozart tried to score on a flyout. The throw easily beat him. He didn't slide and was tagged for the apparent third out. But officials ruled Mathis safe. That tied it, and the ensuing single helped the Reds win 3-1. Friday, MLB said under the rule put in place before this season, Mathis "hindered his path to the plate without possession of the ball."
Brewers: 2B Scooter Gennett was scratched with a left finger injury. Details weren't disclosed.
Cardinals: RHP John Lackey, acquired from Boston on Thursday, will make his first start Tuesday against his ex-team, the Cardinals said.
Marline: RHP Henderson Alvarez, 8-5 with a 2.48 ERA, went on the DL with right shoulder inflammation.
Mets: RHP Matt Harvey threw off a mound for the first time since October's Tommy John surgery. He hopes to return by the start of 2015.
Orioles: RH reliever Ryan Webb, a Clearwater Central Catholic grad, was designated for assignment. He is 3-2 with a 3.80 ERA in 42 games.
Rockies: RF Carlos Gonzalez left in the fifth when he came up limping after making a sliding catch. His status was unknown.
Twins: 1B Joe Mauer (out since July 1 with a strained oblique) and RHP Ricky Nolasco (July 6, sore right elbow) are set to begin rehab stints next week with hopes of returning the following week.
White Sox: Pitching coach Don Cooper returned after missing 11 games with vertigo.
