Red Sox Third Base: Suarez Easiest Fix, Mayer Best In-House

The Boston Red Sox head into the new season with a familiar question: who’s actually going to play third base, both now and down the road? Veteran stars, young prospects, and possible trades are all on the table. The front office has to juggle what works right now with what’ll work later.

Let’s break down the Red Sox’s options at third base. There are free agents, internal names, and maybe even a trade or two as spring training sneaks up.

Evaluating the External Option: Eugenio Suárez

Signing a free agent is probably the most straightforward route. For Boston, that means looking at Eugenio Suárez, a veteran third baseman with real power. Suárez, now 34, can still hit, but you don’t get everything for free.

Power Production Comes at a Cost

Suárez knocked in 118 runs last season, which is hard to ignore. But he strikes out a ton, and the Red Sox lineup has had its own issues with consistency. His defense has slipped lately, which could get tricky at Fenway’s hot corner.

Marcelo Mayer: The Internal Favorite

Inside the system, Marcelo Mayer stands out most. He’s just 23 and was a first-round pick. Last season, Mayer got a shot at third when Alex Bregman went down. He handled himself well on defense.

Growing Pains and Health Questions

Mayer’s bat was another story. In 136 plate appearances, he managed a .674 OPS, which isn’t ideal but not shocking for a young player. His 2024 season ended early thanks to a right-wrist tear that needed surgery. That’s a red flag for durability—he hasn’t played more than 91 games in a season since 2021.

Mayer says he’s almost back to full baseball activity. At the team’s urging, he added 10 pounds of muscle. The Red Sox clearly think his bat can still come around. He should be ready for spring training.

Positional Flexibility Adds Value

Mayer’s versatility keeps him in Boston’s plans. The team believes he could handle second base too, which gives the infield some breathing room if things go sideways elsewhere.

Depth Options Already in the System

After Mayer, the Red Sox have a few backup options, though none look like everyday guys:

Mikey Romero, a 2022 first-rounder, started 45 minor-league games at third. He’s talented, but right now he’s more depth than solution.

Trade Market: Options but Limited Time

The Red Sox could also make a trade, maybe using their surplus in the outfield or pitching staff. Some interesting names are floating around.

Possible Trade Candidates

Guys mentioned as fits include:

But as spring training gets closer, trades get tougher to pull off. Teams settle in with what they have, and prices go up. Sometimes you just have to play the hand you’re dealt.

Looking Ahead to 2025 and Beyond

Trades seem less likely, and free-agent options just aren’t ideal right now. The Red Sox look set to lean on their own internal development instead.

Marcelo Mayer is the projected third baseman for 2026, while Alex Bregman should anchor the position in 2025. It’s a bit of a gamble on youth, health, and growth—maybe risky, but it could shape Boston’s infield for years.
