Marcelo Mayer On Injured List, Another Blow To Red Sox's Infield

An already banged-up infield took another hit.

Second baseman Marcelo Mayer was placed on the 10-day injured list Friday by the Boston Red Sox due to a stress reaction to the left ulna. Shortstop Tsung-Che Cheng was called up from Triple-A Worcester to make his Red Sox debut.

Mayer has been dealing with the forearm issue for a couple months, but it got to the point where the Red Sox decided to shut Mayer down. The Red Sox now have six infielders on the IL, including three on the 60-day IL (Trevor Story, Triston Casas, Romy Gonzalez). Gonzalez, on the mend from surgery on his left shoulder, could return this weekend against the New York Yankees. He was scheduled to play in a rehab assignment for Worcester on Friday. In addition, third baseman Caleb Durbin has a partially dislocated left pinkie finger that he is currently playing through. 

Mayer is slashing .220/.282/.312 with three homers and 22 RBIs in 70 games this season.

Cheng, who bounced around the waiver wire this offseason before finally sticking with the Red Sox, made his MLB debut last season with the Pittsburgh Pirates, going 0-for-7 in three games. At Worcester this year, Cheng has a .254/.351/.424 slash line with seven homers, 18 RBIs and 10 steals in 64 games.
