Pete Alonso had the MLB world stunned after he reportedly agreed to join the Baltimore Orioles on a monster five-year contract on Wednesday, leaving the only home he's ever known in New York.

Following seven productive years in Queens, Alonso will get a fresh start in the AL East in news that has both Mets fans and Red Sox fans alike feeling disappointed. The soon-to-be 32-year-old opted out of his contract after re-signing with the Mets last year; he recorded 38 homers in 2025 and has 264 home runs and 712 RBIs since his pro debut in 2019.

Alonso's massive deal is the most lucrative ever for his position, but just how much does he stand above his peers?

Here's a look at the highest-paid first basemen in the league as ranked by average annual salary according to Spotrac:
