Marcelo Mayer was supposed to solidify himself in 2026 as an MLB contributor for the Boston Red Sox. Then again, the Red Sox were also supposed to be a competitive baseball club in 2026.
Neither of the above expectations have been fulfilled. The Red Sox have been a profound disappointment, and Mayer has had a terrible campaign thus far.
Long lauded as one of Boston's "Big 3" prospects (along with Kristian Campbell and Roman Anthony), the 23-year-old Mayer still hasn't experienced any sustained success in the bigs. Through 114 career MLB games, Mayer is hitting a dreadful .223/.278/.346. Defensively, fans were pumped when Mayer recently got the opportunity to operate as Boston's starting shortstop (with Trevor Story out), but Mayer has underwhelmed in the role.
Fans' complaints about Mayer reached a fever pitch on Wednesday when he had two ugly defensive gaffes at shortstop, one of which seriously ticked off Ranger Suarez. On Friday, a report surfaced from MassLive's Sean McAdam that there are individuals within the Red Sox organization who aren't high on Mayer in general.

Latest Marcelo Mayer report makes his future with the Red Sox look murky
The issues supposedly stem from Mayer's character and/or approach. This is a very notable development because those types of issues generally lead to a player falling out of favor with an organization and ultimately getting traded.
There's been some decent buzz around Mayer trades in the past — with one incident even resulting in media members thinking he'd actually been dealt — but on the whole, Red Sox fans have always viewed Mayer and Anthony as future pillars of the franchise.
Does Boston's upper management think differently, particularly when it comes to Mayer?
Red Sox's wonder boys have crashed back down to Earth
Mayer, Anthony, and Campbell looked like a future superstar trio at the start of the 2025 MLB season, with Campbell dominating out of the gate in the majors and Anthony and Mayer awaiting their debuts. Anthony thrived in his first season with Boston, earning himself a lucrative extension and the label of Boston's future franchise player.
In the past year-plus, Campbell has suffered a massive decline and is stuck in Triple-A, Anthony has proved to be injury-prone, and Mayer hasn't yet blossomed. In other words, the hype hasn't delivered results when it comes to this Big 3, two of whom are signed long-term with the Sox.
What went wrong? It's still very early in all three of these guys' careers, but it's worth wondering whether the Red Sox have already botched elements of their development (they've certainly messed up with Campbell). Is it possible that Boston jumped the gun on thinking these guys were going to be the next franchise cornerstones? It's a question that no one would be asking if the Red Sox were winning games in 2026, but we're miles away from that prospect.
