Marcelo Mayer (forearm) has been cleared to start a hitting progression.
Mayer landed on the injured list with a stress reaction in his left forearm. He was allegedly playing through the injury for two months, which may have impacted his performance on the field. It may just be a couple of weeks before Mayer could begin a rehab assignment, but his role in Boston for the remainder of the season remains to be seen. The team has been thriving, and they have multiple options in the infield with Romy Gonzalez back and Anthony Seigler and Tsung-Che Cheng providing value. The Red Sox could opt to keep Mayer in Triple-A to get consistent at-bats until rosters expand in September.
