The MLB Offseason's Top 10 Roster Revamps: A New Look for 2026
Every team strives for perfection, but the quest for improvement never ends. The offseason is a pivotal period for front offices to address their squads' shortcomings and build a stronger foundation for the upcoming season. As we approach Spring Training, let's delve into the 10 most significant upgrades teams made, either through free agency or trades, to bolster their chances in 2026.
These moves might not guarantee immediate success, but they demonstrate a clear commitment to addressing the issues that plagued these franchises in 2025.
Athletics: Revitalizing Second Base
In 2025, the A's second base position was a source of concern. Zack Gelof's injury-plagued season limited him to just 30 games and a .502 OPS. Luis Urías and others filled in, but the position's collective performance was abysmal, with a 53 wRC+, one of the lowest marks in the league.
Enter Jeff McNeil: The Athletics acquired the former NL batting champion from the Mets. While McNeil's recent performance has been average (102 wRC+), it's a substantial upgrade for Oakland's second base woes.
Cubs: Securing the Hot Corner
The Cubs' pursuit of Alex Bregman in free agency fell short, leaving them with prized prospect Matt Shaw at third base. Shaw's struggles led to a .690 OPS over 126 games.
The Bregman Deal: Chicago made a bold move by signing Bregman for $175 million over five years after he opted out of his Red Sox contract. This addition of one of baseball's elite third basemen became crucial with Kyle Tucker's potential departure and the need to strengthen their batting order.
Dodgers: Reinventing the Bullpen
Last offseason, the Dodgers invested heavily in Tanner Scott ($72 million) and Kirby Yates ($13 million), but both signings flopped. Scott had a 4.74 ERA with 10 blown saves, and Yates missed most of the season. Despite these setbacks, the Dodgers claimed their second consecutive World Series title.
Left Field Reinforcements: Michael Conforto's underwhelming performance (.637 OPS, -0.6 WAR) prompted the Dodgers to sign Kyle Tucker, the top free agent, for a staggering $240 million over four years. Tucker's arrival allows Teoscar Hernández to shift to left field, effectively filling Conforto's role.
Mets: Revamping Center Field
Jose Siri's injury-shortened season left the Mets scrambling for a center fielder. Tyrone Taylor filled in until the acquisition of Cedric Mullins, who struggled post-trade. Mets center fielders collectively hit only seven home runs with a 71 wRC+ and 0.7 fWAR.
The Luis Robert Jr. Gamble: The Mets traded for Robert, assuming his hefty contract, in hopes of reviving his 2023 All-Star form (38 HR, 20 SB, .857 OPS). It's a risky move, as Robert has battled injuries and underperformed in recent years, posting a .660 OPS with 1.8 fWAR in 210 games.
Orioles: First Base Reinforcement
Baltimore's first base production was lackluster in 2025, ranking 22nd with a 92 wRC+ and a league-low 14 home runs. Ryan Mountcastle, their Opening Day starter, managed only two home runs before a hamstring injury.
Pirates: Strengthening the Keystone
Pittsburgh's 2025 season was marred by a lack of offense, ranking last in runs scored. Second base was a weak spot, contributing just eight homers and an 80 wRC+.
Brandon Lowe's Arrival: The Pirates acquired Lowe from the Rays in a three-team trade, addressing their second base concerns. Despite injury concerns, Lowe has been a power hitter, ranking third among second basemen with 120 home runs in the last five years.
Red Sox: First Base and Rotation Upgrades
The Red Sox acquired Willson Contreras from the Cardinals, a former catcher who transitioned to first base in 2025, posting a solid 2.8 fWAR season. Contreras' addition became even more crucial after Bregman signed with the Cubs.
Rotation Reinforcements: Boston's rotation had its ups and downs in 2025. While Garrett Crochet, Brayan Bello, and Lucas Giolito excelled, the rest struggled, including the disappointing signing of Walker Buehler and Tanner Houck's rough season (8.04 ERA). The Red Sox addressed this by acquiring Contreras, ensuring a more stable rotation.
White Sox: First Base Overhaul
The White Sox moved on from Andrew Vaughn after a disappointing start (.531 OPS in 48 games). The team's first base production finished the season with an 83 wRC+ and -0.5 fWAR.
Honorable Mentions: The Pirates' designated hitter, Blue Jays' starting rotation, and Royals' left field also underwent notable upgrades, but the above teams made the most substantial moves.
And there you have it—the top 10 positional upgrades that could shape the 2026 MLB season. But here's where it gets controversial: are these moves enough to guarantee success? Share your thoughts in the comments, and let's spark a lively debate!
