The Mariners have traded SS Asdrubal Cabrera to the Indians for 1B/LF/DH Eduardo Perez.
Perez is a lefty masher who can help the team (.303/.343/.636 in 99 at-bats this year), but this is way too high of a price to pay. He’s basicalliy a strict platooon player, getting 88 of his 99 at-bats vs lefties. He hit .259/.371/.526 vs lefties and just .231/.355/.346 vs righties last year.
This probably sends Mike Morse back to the minors, and Perez will become the DH vs left handed pitchers. The team gets better, but this isn’t a huge upgrade. It’s a minor upgrade that cost them a top prospect.
The team is better, but the price to pay was too high.
