There’s been a ‘Polar Bear’ sighting in Baltimore.

Per ESPN’s Jeff Passan, first baseman Pete Alonso and the Baltimore Orioles have agreed to a five-year deal worth $155 million. This is still pending a physical, and it is not known if there are any deferrals or options in the contract.

Alonso joins the Orioles after spending seven years with the New York Mets, who drafted the Florida product in the second round of the 2016 MLB Draft. With the NL East squad, Alonso racked up five All-Star nominations, a Silver Slugger Award (2025), the NL Rookie of the Year (2019), and is a two-time Home Run Derby winner.

The right-handed bat is one of the top sluggers in the game, racking up 30+ home runs each season since his big league debut (outside of the condensed 2020 season), including a league-leading 53 home runs in 2019. Alonso has posted an OPS above .800 in six of those seven campaigns and boasts a career .857 OPS across 1008 games. Since 2019, only Aaron Judge and Kyle Schwarber have more home runs. For his career, Alonso owns a .253/.341/.516 slash line with 183 doubles, 264 home runs, and 712 RBIs.

Alonso also boasts a strong postseason track record, collecting five home runs and a .278/.429/.574 slash line with a 1.003 OPS across 16 games, spanning back to 2022. One of his most memorable knocks was against the Milwaukee Brewers in the 2024 NL Wild Card, sending the Mets to the NLDS thanks to a three-run blast in the ninth inning off closer Devin Williams.

For Alonso, he gets the long-term security he is looking for on the free agent front. Last winter, he and the Mets struggled to find common ground, eventually signing a two-year deal worth $54 million that included an opt-out following the 2025 season. Alonso is the second high-profile player the Mets have lost this winter, with reliever Edwin Diaz signing with the Los Angeles Dodgers earlier this week.

The Baltimore Orioles’ newest addition gives them one of the best lineups in the league. Alonso joins a group that includes Adley Rutschman, Samuel Basallo, Gunnar Henderson, Jackson Holliday, Jordan Westburg, Dylan Beavers, Taylor Ward, Colton Cowser, Tyler O’Neill, and Heston Kjerstad.
