After waiting until February last year to find a free agent home, Pete Alonso has signed a five-year contract with the Baltimore Orioles, making him one of the top-paid first basemen in MLB history. This move provides the Orioles with valuable power and raises questions for the New York Mets as they face a lineup transformation for the upcoming season.

Impact on Alonso’s 2026 Fantasy Value

Alonso’s transition to Camden Yards is noteworthy. Statcast data reveals that had he played there over the past seasons, he could have hit 158 home runs. The overall environment is expected to be more advantageous for hitters, compared to his previous home field.

While the Orioles are strengthening their offense with additions like Taylor Ward, Alonso’s position in the lineup will change; he shifts from hitting behind star players like Francisco Lindor and Juan Soto to a less prominent position. This could diminish his run production.

Consequences for the Orioles

The acquisition hints at challenges for Coby Mayo, likely limiting his chances to play regularly in 2026. Other players, including Ryan Mountcastle and Heston Kjerstad, might also see opportunities reduced due to Alonso’s signing.

Additionally, Adley Rutschman and Samuel Basallo may need to adjust their roles, especially with the pressure on Basallo to excel in a more fixed position.

What’s Next for the Mets?

For the Mets, losing Alonso, along with others like Brandon Nimmo and Edwin Diaz, leaves a significant gap in their lineup. With roster changes and a strong farm system, they need to act quickly to fill the void left by these departures as they prepare for 2026.
