Trade Details

Boston Red Sox are finalizing a deal that sends infielder Marcelo Mayer to the San Francisco Giants for left‑handed reliever Erik Miller. The transaction, reported by The Athletic’s Ken Rosenthal, is set to be completed just before the trade deadline.

Marcelo Mayer’s Recent Numbers

Twenty‑three‑year‑old Mayer has logged 332 major‑league at‑bats, posting seven home runs, a .223 batting average and a .625 OPS. His OPS+ slipped to 69 this season before he landed on the injured list, diminishing his trade value.

Historical Background

When the Red Sox drafted Mayer in 2022, he was hailed as one of the organization’s brightest prospects, quickly drawing comparisons to early‑career legends like Aaron Judge. However, recurring injuries and a crowded infield have stalled his development, making his future with Boston uncertain.

Miller, under team control through 2029, has posted a 2.76 ERA, a 2‑0 record, four saves and 45 strikeouts over 32.2 innings, offering a reliable left‑handed option for a postseason run.
