The Boston Red Sox are watching the 2025 American League Championship Series from their couches, with the Toronto Blue Jays and Seattle Mariners battling it out for the pennant. It’s a bitter pill to swallow for Red Sox fans, who can’t help but feel their team was just a few key players away from being in the mix. Fortunately, the rosters of the teams still playing offer some intriguing options for Boston to pursue this offseason. Here are three players the Red Sox should target to transform their roster into a World Series contender in 2025.
Eugenio Suárez, 3B, Seattle Mariners
Eugenio Suárez might not be the flashiest name, and signing him could raise some eyebrows among Red Sox fans hoping for a bigger splash. But hear us out: Suárez as a power-hitting hired gun could be a game-changer. His ability to crush 40 home runs, especially with the Green Monster beckoning, makes him an ideal fit for Fenway Park.
While primarily a third baseman, Suárez could slide to first base against left-handed pitchers or serve as a designated hitter, providing lineup flexibility. His on-base percentage dipped below .300 by the end of the 2025 season, marking him as a one-dimensional slugger. However, as he proved in a pivotal moment during the playoffs, one swing from Suárez can shift the course of an entire season. For a Red Sox team desperate for offensive firepower, he’s a low-risk, high-reward addition.
Shane Bieber, SP, Toronto Blue Jays
The Red Sox had their eyes on Shane Bieber last offseason, but he re-signed with the Cleveland Guardians before being traded to the Toronto Blue Jays. Now, with a 3.67 ERA across nine regular season and postseason starts in 2025, Bieber is set to take the mound in the decisive ALCS game. His performance proves he’s still a reliable arm, and Boston should make a strong push to sign him this winter.
Bieber might not be the undisputed No. 2 starter the Red Sox crave, and his signing might not thrill every fan. However, with the market for top-tier pitchers driving prices sky-high, Bieber could represent Boston’s biggest pitching acquisition. His experience, poise, and ability to log quality starts make him a valuable addition to a rotation that needs stability and depth to compete in 2025.
Michael Kopech, RHP, Los Angeles Dodgers
When it comes to the Dodgers, the Red Sox could consider a reunion with fan-favorite Kiké Hernández, whose postseason heroics are undeniable. But with Hernández likely staying in LA and some rocky history from his last stint in Boston, the smarter move might be targeting Michael Kopech, a former Red Sox prospect traded away in the blockbuster deal that brought Chris Sale to Boston nine years ago.
Kopech, when healthy, still brings electric velocity that lights up radar guns—an attribute the Red Sox bullpen covets. Pairing him with high-leverage relievers like Garrett Whitlock and Justin Slaten could give Boston a formidable late-inning trio. Kopech’s injury history makes him a bit of a gamble, but his upside as a hard-throwing righty makes him a compelling reclamation project for a team looking to bolster its relief corps.
The Red Sox’s 2025 season hinges on bold moves to address their roster’s weaknesses. Adding Suárez’s power bat, Bieber’s steady arm, and Kopech’s high-octane relief potential could elevate Boston from playoff hopefuls to legitimate World Series contenders. These three deals, if executed, might just make the Red Sox a stone-cold lock to hoist the trophy at Fenway next October.
