The Baltimore Orioles made one of the biggest splashes of the MLB offseason Wednesday, agreeing to a five-year, $155 million deal with free-agent first baseman Pete Alonso. The contract, which includes a limited no-trade clause and no opt-outs, represents the largest free-agent commitment of Mike Elias’ tenure, the highest AAV ever received by a first baseman, and instantly places a premier power bat in the center of Baltimore’s lineup.
Alonso, a five-time All-Star and former Rookie of the Year, played all 162 games last season with 38 home runs, 41 doubles, and 126 RBI.
The move signals an aggressive shift for a franchise that has repeatedly emphasized its financial flexibility under new ownership. Alonso fills a long-term need at first base and surpasses the Orioles’ recent offer to Kyle Schwarber, who was reportedly pitched a five-year, $150 million deal before choosing Philadelphia. The signing also raises immediate roster questions, particularly regarding Ryan Mountcastle, who is projected to make roughly $8 million in arbitration, and prospect Coby Mayo. Alonso’s arrival likely forces a corresponding move.
Baltimore’s front office indicated earlier this week that adding a frontline starter remains a priority, and the Alonso deal does not push the club near last year’s payroll level, suggesting more activity could follow before the winter meetings conclude.
