Zach Putnam underwent Tommy John surgery - MLB

White Sox reliever Zach Putnam underwent Tommy John surgery last week, CSN Chicago’s Dan Hayes reports.

Putnam, 29, had been on the disabled list since late April with a right elbow injury. He was cleared to begin throwing last month but was shut down after experiencing more elbow discomfort earlier this month. Putnam had surgery on his right elbow last August to remove a bone fragment as well, so it was an issue that had been nagging him for more than a year.

Putnam appeared in only seven games this season, giving up one run on two hits and a walk with nine strikeouts in 8 2/3 innings. The White Sox won’t be able to count on him until the middle of next season at the earliest.

LOS ANGELES — Giancarlo Stanton, Josh Donaldson, and Tommy Kahnle were activated by the New York Yankees ahead of their weekend series against the Los Angeles Dodgers.

New York cleared three roster spots after a 1-0 loss at Seattle, optioning infielder-outfielders Oswaldo Cabrera and Franchy Cordero to Triple-A Scranton/Wilkes-Barre along with left-hander Matt Krook.

Stanton, Donaldson and Kahnle all played in a rehab game for Double-A Somerset. Stanton was hitless in three at-bats in his first appearance since injuring his left hamstring on April 15.

Donaldson went 1 for 4 in his fourth rehab game as he comes back from a strained right hamstring originally sustained on April 5.

Kahnle pitched one inning, giving up one run and one hit and walking two. He has been out since spring training with right biceps tendinitis.

Aaron Boone said he wasn’t concerned about Stanton returning after playing in just one rehab game. He did say that Stanton likely will be a designated hitter for a couple of weeks after rejoining the Yankees.

New York is missing centerfielder Harrison Bader, who strained his right hamstring against the Mariners and went on the injured list the next day.

Left-hander Carlos Rodón, sidelined since spring training by a sore left forearm and an ailing back, was transferred to the 60-day injured list.
