Zack Cozart diagnosed with hyperextended left elbow - MLB

UPDATE: Mark Sheldon of MLB.com reports that Cozart was diagnosed with a hyperextended left elbow and that X-rays came back negative. It’s not clear when he’ll be able to return to the lineup, but it sounds like the Reds may have dodged a bullet here.

5:45 PM: Here’s some potentially bad news for the Reds as they attempt to hang around in the National League Central.

According to David O’Brien of the Atlanta Journal-Constitution, Reds rookie shortstop Zack Cozart left today’s game against the Braves with an apparent injury to his left arm following an awkward collision with Nate McLouth at second base in the fourth inning. No word on the severity of the injury yet, but Buster Olney of ESPN.com likened the play to how Albert Pujols injured his arm last month.

Cozart, 25, has been a breath of fresh air since supplanting Paul Janish and Edgar Renteria at shortstop earlier this month, batting .324 with two homers, three RBI and an .811 OPS over his first 37 major-league at-bats.

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.
