He put up a career season, and took a 3-year deal at 25 million annually with an opt out after the first year. I'm gonna go ahead and guess that he wants to build/strengthen his value in 2016 and opt-out in the hopes of getting a much larger contract, say 6yrs/130mil. At worst, he bombs in 2016 and then has 2 more years at 25 million to rebuild his value for a big contract after the 2018 season.
Bautista has been consistently elite for like 5 straight years now. He will get at least 20 million a year, mark my words.
