Alonso split last season between the Oakland A’s and the Seattle Mariners where he hit .265/.866 with 28 homers and 68 RBI’s. These stats, with the exception of RBI’s, were better than Mitch Moreland.
Alonso: 142 Games .265 / .866 OPS / 28 HR / 68 RBI
Moreland: 149 Games .246 / .769 OPS / 22 HR / 79 RBI
Alonso, like Moreland, is a left-handed hitter who would provide the lineup with a bit more right / left balance, as well as lengthen the lineup the same way Moreland did a year ago.
The clear advantage that Moreland holds over Alonso is on defense. Moreland’s defensive abilities are much better than those of Alonso, as Moreland received the Gold Glove at first base in 2016.
However, Alonso isn’t a black hole over at first base either and is an adequate first baseman. The former Athletic can also play a little bit of 3rd, as well as DH, and play outfield – allowing Cora more choices.
Similar to Moreland, signing a 1-year deal, Alonso could be a bargain. He would come at a much lower price and commitment length than Eric Hosmer and Carlos Santana. In addition, Alonso would not cost the Red Sox draft pick compensation, as he was not tendered a Qualifying Offer.
The Mariners have already acquired Ryan Healy, potentially eliminating them from getting into a bidding war over their ex-first baseman. This could open the door for the Red Sox to acquire a solid talent at a reasonable price.
