Boston Red Sox Infield Shakeup: Who Will Start on Opening Day? (2026)

The Boston Red Sox infield is a puzzle, and the pieces are still flying in! With Alex Bregman's departure, the team has been busy shuffling its roster, bringing in new talent and strategizing how to fill the gaps. But here's where it gets interesting: how will all these new faces and returning players gel to form a winning infield?

As Red Sox faithful navigate the post-Bregman era, the front office has been actively working to reinforce the infield. In the past month alone, the team has welcomed Isaiah Kiner-Falefa and Brendan Rodgers into the fold. They've also made a significant trade, acquiring Caleb Durbin and Andruw Monasterio from the Milwaukee Brewers. Adding to the mix, Willson Contreras, who originally began his career as a catcher, is set to be the primary first baseman while Triston Casas continues his recovery from a torn patellar tendon. This three-time All-Star was a notable acquisition via trade back in December.

This flurry of activity provides Boston with a wealth of options to finalize their infield. However, it's crucial to remember the strong contingent of players who were part of last year's playoff squad and are still with the team. Trevor Story, Marcelo Mayer, and the currently injured Romy Gonzalez all played vital roles last season and remain on the Red Sox payroll for the upcoming year. We also can't forget Kristian Campbell, who had a blazing start to the season before encountering some struggles and being sent down to the minors in June. Campbell also showcased his versatility by spending time in the outfield, a position already brimming with talented players.

So, the burning question remains: who will be manning the infield on Opening Day and throughout the season? Manager Alex Cora has quite a few strategic decisions to make for his squad.

The locks for the infield, without a doubt, are Story and Contreras. These two seasoned veterans have undeniably earned their starting spots as Boston prepares to take the field for the first time on March 26th.

However, the second and third baseman positions are very much up for grabs. This is where the real competition and intrigue lie.

Many fans would likely point to Mayer as their preferred choice, but his recurring injury concerns are starting to become a significant worry. This former first-round pick in 2021 has never managed to play more than 91 games in a single season, and his 2025 campaign was cut short by wrist surgery in July. While his talent is undeniable, his health will undoubtedly be a major storyline to watch throughout the 2026 season.

Durbin is a player who is perhaps underrated by many. As a rookie, Durbin impressively finished third in the NL Rookie of the Year voting, accumulating a WAR of 2.8 over 136 games. This soon-to-be 26-year-old can effectively play both second and third base. The third base position, in particular, presents a massive void to fill following the departure of Bregman and the trade of Rafael Devers last June.

Monasterio offers valuable depth for Cora's bench. With a career on-base percentage of .321 and a notably low strikeout rate, Monasterio is poised to provide solid hitting and dependable defense on the right side of the infield.

And then there's Kiner-Falefa. Making his third stop in the AL East after his time with the Yankees and Blue Jays, he inked a one-year, $6 million contract with the Red Sox. Kiner-Falefa is known for his versatility across the infield and his all-out effort on the field. Despite a memorable blunder in Game 7 of last year's World Series, Kiner-Falefa is generally reliable for making the correct play. This is precisely why Boston brought him in, especially after years of being near the top of the error leaderboard.

Rodgers presents a particularly intriguing case. The 29-year-old missed a significant portion of last season due to a lengthy list of injuries, which ultimately led to his departure from the Astros after just one year. His most impressive season came in 2022 with the Rockies, where he recorded 140 hits in 137 games. That same season, Rodgers also earned a Gold Glove at second base, a skill that would be incredibly valuable for the Red Sox infield. If Rodgers can consistently provide above-average defense, he has a strong likelihood of becoming a fixture in the lineup.

Finally, we have Nate Sogard and Nate Eaton. Both of these players saw time at the major league level last season, including appearances in the playoffs. Cora might lean towards these two, given his established rapport with these younger talents.

With spring training just getting underway, there's still ample time for Cora and his coaching staff to finalize their decisions. However, the core foundation of the infield is undeniably in place; now, it's a matter of fitting all the pieces together perfectly. What are your thoughts on the Red Sox infield situation? Do you agree with these assessments, or do you see different players stepping up? Let us know in the comments below!
