For years, the Boston Red Sox sold their fans on a more sustainable future of competing on the backs of homegrown prospects rather than big-ticket free agent signings. Among the prospects that future was built around was 2021 No. 4 overall draft pick shortstop Marcelo Mayer. It hasn’t been the start to the major league career that anyone had hoped for, but does the 23-year-old need a change of scenery like one prominent outlet has suggested? 

Baseball America released its list of “change of scenery” trade deadline candidates: former top prospects who, thus far, haven’t panned out with their current teams. Among those prospects listed was Mayer, with BA’s Ian Cundall writing, “Injuries have disrupted both his minor league and major league careers... He was considered a top 10-15 prospect in baseball for five years, even though his minor league production was more solid than spectacular. Mayer has struggled against big league secondaries down in the zone, an issue that was also prevalent in the minors.” 

“With Boston jumping back into the playoff picture with Mayer on the injured list, he’s an appealing trade chip if the Red Sox pursue a major move to bolster their lineup,” he continued. 

Prior to landing on the injured list thanks to a stress reaction in his left forearm, Mayer was hitting only .220/.282/.312/.594 while playing both shortstop and second base. As Cundall notes, the 23-year-old struggles with offspeed pitches, particularly changeups, where he has hit just .125 in 32 at-bats.  The trip to the IL marks the second of Mayer’s short MLB career, after the former first-round pick missed the final 58 games of 2025 with a right wrist sprain.  

Injuries have undoubtedly become part of Mayer's story, as he has missed time in each of his five professional seasons. Prior to his placement on the injured list due to the stress reaction, MassLive.com’s Sean McAdam reported that there were some in the Boston organization who questioned his toughness and ability to play through the “day-to-day minor physical setbacks” associated with playing a full 162-game season. 

Throughout the offseason, the 23-year-old found himself in trade rumors, most notably being linked to the Arizona Diamondbacks in conversations surrounding All-Star second baseman Ketel Marte. However, Boston was unwilling to part with their former fourth overall pick in any deal for Marte, believing him to be a franchise cornerstone. 

Now, as he struggles to establish himself at the major league level, he not only finds himself back in trade rumors as the Red Sox reportedly pursue middle infield help ahead of the trade deadline. But, being pushed by the Red Sox' newest top prospect, shortstop Franklin Arias, who hit .318/.407/.587/.994 in 75 games with Double-A Portland before being promoted to Triple-A on Friday. 

While Mayer could very well find himself on a new team come the trade deadline, the phrase ‘change of scenery’ implies that the relationship has soured on one side or the other, with things no longer working out. While Mayer has yet to perform to his prospect status, he still has just 114 major league games under his belt. It is far too early to determine that things are no longer working out. 

If Chief Baseball Officer Craig Breslow chooses to move Mayer, it should be only for meaningful upgrades to the lineup, rather than to swap two depreciated assets. 

It’ll be a clash of two of the best pitchers in the American League as the Red Sox look to make it six consecutive series wins on Saturday afternoon in game two of three with the Toronto Blue Jays. Sonny Gray (12-1, 2.48 ERA) gets the start for Boston opposite Dylan Cease (6-5, 2.65 ERA) for Toronto. First pitch from Fenway is set for 4:10 p.m. ET.
