2025 Fantasy Outlook
Mayer mastered Double-A (142 wRC+ in 77 games) after struggling at that level in 2023 (63 wRC+ in 43 games), but after another injury-marred season, his fragility is starting to become his most discussed quality. His 91 games in 2022 represent a career high, and perhaps fittingly, he was promoted to Triple-A in early August but never got into a game for Worcester due to hip and back injuries. He slashed .307/.370/.480 with eight home runs, 13 steals, a 19.7 percent strikeout rate and an excellent 31.5 percent hard-hit rate as a 21-year-old repeating Double-A. Mayer's best skills are his shortstop defense, followed by above-average power and a potentially above-average hit tool. He has multiple years with double-digit steals in the minors, but Mayer's pure speed is average at best, so we can't bank on him making a notable impact in stolen bases. Even if Mayer reached his realistic fantasy ceiling, he'd be a fringe top-15 fantasy shortstop due to the lack of a standout tool, and his durability issues make it difficult to sell him as a potential compiler in the Dansby Swanson mold. He'll be an option this summer if he's healthy and Trevor Story is hurt or struggling. Read Past Outlooks
Hitting bench vs. southpaw
Mayer is out of the lineup for Sunday's game against the Yankees, Mac Cerullo of the Boston Herald reports.
ANALYSIS
With southpaw Carlos Rodon taking the hill for the Yankees, the left-handed-hitting Mayer will retreat to the bench after going 2-for-3 with a solo home run and an additional run in the first two contests of the series. Abraham Toro will replace Mayer at third base.

Stat Review
How does Marcelo Mayer compare to other hitters?
This section compares his stats with all batting seasons from the previous three seasons (minimum 400 plate appearances)*. The bar represents the player's percentile rank. For example, if the bar is halfway across, then the player falls into the 50th percentile for that stat and it would be considered average.
* Exit Velocity and Barrels/PA % are benchmarked against 2019 data (min 400 PA) and Hard Hit Rate is benchmarked against last season's data (min 400 PA). See here for more exit velocity/barrels stats plus an explanation of current limitations with that data set.

Past Fantasy Outlooks
2024
2023
2022
Mayer will be a big-league regular, but the closer he gets to the majors, the less he looks like a future fantasy star. As one of the slower shortstop prospects of note, Mayer won't be a major threat on the bases, so he has to move the needle at the plate. His walk rate has decreased at every full-season stop, dipping to 7.9 percent in 43 games at Double-A, and his 25.8 percent strikeout rate at Double-A was the worst mark of his career. Mayer reportedly dealt with a left shoulder impingement during his struggles at Double-A, and he eventually got shut down in early-August and received an injection in September. He has a career .280/.371/.494 slash line with 11 home runs in 60 games at High-A, so if the injury was the cause of his issues at Double-A, he could bounce back with similar production to what he showed at High-A in 2022 and 2023. A big reason Mayer ranks highly on real-life prospect rankings is his plus defense at shortstop, and while that figures to guarantee him playing time in the future, that's the extent of its importance for his fantasy value. He could debut late this year, but don't expect him to produce at an acceptable clip in fantasy until at least 2025.

Latest Fantasy Rumors
Call-up after Bregman injury?
Red Sox manager Alex Cora on Saturday didn't rule out the possibility of Mayer being called up from Triple-A Worcester following Alex Bregman's quadriceps injury, Rob Bradford of WEEI.com reports.
ANALYSIS
Bregman injured his right quad while rounding first base in Friday's game against the Orioles. Mayer's name had been floated around for a promotion to the majors after Triston Casas suffered a season-ending knee injury in early May, and the former could be on his way to the big club to provide infield depth if Bregman needs a stint on the injured list. Mayer is slashing .265/.342/.465 with two steals, nine home runs and 43 RBI over 193 plate appearances in Triple-A this season.
