Red Sox call prospect Mookie Betts up to the major leagues - MLB

The Red Sox have promoted prospect Mookie Betts up to the big leagues, John Tomase of the Boston Herald reports. The 21-year-old will be available for Saturday night’s match-up against the Yankees in the Bronx.

Update: Via Ken Rosenthal of FOX Sports, the Red Sox sent Rubby De La Rosa down to Triple-A Pawtucket to make room for Betts on the 25-man roster.

Drafted out of high school by the Red Sox in the fifth round of the 2011 draft, this is just the fourth year of professional baseball for Betts. He started the season at Double-A Portland for the first time and quickly moved up to Triple-A Pawtucket, slashing a combined .345/.437/.520 with eight home runs, 48 RBI, and 29 stolen bases in 34 attempts.

Betts has traditionally been an infielder, but started playing the outfield more as the Red Sox have the third-lowest outfielder OPS in baseball. Additionally, the Sox had to shut down Shane Victorino for the time being after he experienced a setback during his rehab assignment due to back soreness.

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.
