The Baltimore Orioles finalized a five-year, $155 million contract with first baseman Pete Alonso on Wednesday, marking the franchise's most significant free-agent acquisition in history.
The agreement, pending a physical examination, commits the slugger to remain in Baltimore through the 2030 season.
The deal represents a substantial investment in offensive firepower for an Orioles organization that finished in last place in the American League East during 2025 with a 75-87 record. The contract includes a limited no-trade clause but contains no deferrals or opt-out provisions.
Alonso, who turned 31 on Sunday, established himself as one of baseball's most reliable power hitters during his tenure with the New York Mets, recording 264 home runs over seven seasons.
Alonso's 2025 season provided the catalyst for his return to prominence in free agency. Playing behind Juan Soto for the first time in his career, the right-handed slugger delivered a career-resurgent campaign, posting a .272 batting average with a .347 on-base percentage and .524 slugging percentage.
His 38 home runs and 126 runs batted in resulted in a 144 OPS+ rating and earned him his first Silver Slugger Award. His 41 doubles led the National League, and he significantly reduced his strikeout rate while maintaining exceptional exit velocity, which registered at 93.5 miles per hour—approaching the 97th percentile and substantially higher than his previous career best.
The dramatic swing in Alonso's fortunes highlights the volatility of modern baseball's free-agent market. Following a disappointing 2024 season when he produced a career-low .217 batting average, 34 home runs, and 88 runs batted in, teams grew hesitant about committing long-term resources to the aging first baseman.
The previous winter, Alonso's initial free-agency foray yielded modest interest, ultimately resulting in a two-year, $54 million contract that reunited him with the Mets, a deal structured with $30 million due in 2025 and an opt-out clause.
The Orioles' pursuit of Alonso represents their second attempt at landing a prominent power hitter during this offseason cycle. Baltimore had previously offered Kyle Schwarber a five-year, $150 million contract, but the outfielder opted to return to the Philadelphia Phillies.
With that financial commitment redirected toward Alonso, the Orioles secured the right-handed bat they sought to bolster their lineup's middle order.
Alonso's impact on Baltimore's offense projects to be immediate. The Orioles struggled to find consistent production from the middle of their lineup despite possessing promising young talent in second baseman Gunnar Henderson and catcher Adley Rutschman.
Henderson's 2025 performance yielded a .253 batting average with 17 home runs and a subpar OPS, reflecting the broader offensive malaise that plagued the roster. With Alonso now occupying the first-base position—a role he has nearly exclusively played over the past two seasons—the Orioles gain a proven power source capable of generating substantial run production regardless of ballpark dimensions.
The Camden Yards dimensions favor Alonso's particular skill set. Right-handed hitters at Baltimore's facility have struggled since the organization modified the left-field wall, making Alonso's acquisition particularly strategic for park-specific advantage.
His career average of 42 home runs per season provides a tangible floor for the franchise's power-hitting aspirations.
Alonso's contractual commitment extends beyond immediate performance expectations. When combined with his previous earnings—the $30 million earned in 2025 and the $20.5 million earned during his final arbitration year—Alonso will accumulate $205.5 million across the seven-year span that the Mets offered him in 2023 when he rejected a seven-year, $158 million extension.
The additional earnings represent a 30 percent increase over that original offer, validating his gamble to return to free agency.
The Mets organization absorbed significant losses during this offseason. Beyond Alonso's departure, closer Edwin Díaz signed a three-year, $69-93 million contract with the Los Angeles Dodgers, leaving New York to rebuild its roster.
The team also traded outfielder Brandon Nimmo to the Texas Rangers for Gold Glove second baseman Marcus Semien.
The Orioles have indicated that Alonso's acquisition does not complete their offseason agenda. The franchise previously signed reliever Ryan Helsley and acquired outfielder Taylor Ward through trade, demonstrating continued commitment to competitive roster construction.
Pitching remains a priority, as Baltimore's rotation produced a 4.65 earned run average during 2025, a significant weakness that management must address.
Maryland Governor Wes Moore celebrated the acquisition on social media, characterizing the signing as "Christmas came early," reflecting the broader sentiment within the Baltimore community regarding the team's aggressive offseason approach.
The move signals organizational determination to reverse the franchise's recent trajectory following disappointing performances despite having accumulated young talent.
Alonso's arrival represents a calculated investment in proven veteran performance. While baseball history contains cautionary tales regarding substantial contracts awarded to aging first basemen—most notably Prince Fielder and Ryan Howard—Alonso's demonstrated improvements in plate discipline, exit velocity, and overall approach suggest his revival extends beyond temporary regression to the mean.
Should these enhancements prove sustainable through subsequent seasons, the Orioles may have secured meaningful offensive production during the prime years of their young core players' development.
