Marcelo Mayer placed on IL as Red Sox expect month-long absence

The Boston Red Sox have placed shortstop Marcelo Mayer on the 10-day injured list due to a stress fracture. Mayer, 23, has been dealing with left arm soreness for months, which he had not disclosed prior to this announcement. An independent doctor, Jesse Morse, suggests that Mayer could miss over a month due to the severity of the injury. In his absence, Tsung-Che Cheng has taken over as the starting shortstop, although he has struggled since his debut. The team has not provided a specific timeline for Mayer's return.
