Montalvo, who had been with the Beavers organization since its inaugural year, had recently voiced his displeasure about the franchise’s recent move to Portland, and refused to sign an extension with the club. The second-leading all-time career home run hitter and potential Hall of Famer Montalvo gets to join a contending franchise in the last year of his deal, and be reunited with his favorite GM, who now heads the Boston organization. Montalvo is on pace for 28 HRs this year, by far the lowest of his career, and an abhorrent -1.0 WAR. Boston will likely start Montalvo at 1B every day, although they might be better off with almost anyone else.
The prospects Portland received in return, Santos and Aguilar, are both future relievers. I had Santos rated as a 40 FV in my recent minor league system rankings, and Aguilar didn’t even rank. OSA now has Santos ranked as Portland’s 9th-best prospect, and Aguilar 12th. While the return may seem light, getting rid of Montalvo’s contract -- and his attitude problems -- is a huge win for the Beavers.
