Short of them agreeing to a contract extension like Longo, I can't imagine he'd be up prior to late June/early July. It really is unfortunate because I think his impact would be both immediate and significant.
If that's the going rate for career 98 ERA+ pitchers.....yeesh He was also pitching with perhaps the single most unsuitable defense behind him given his pitching style. Put him on the Orioles and I bet he's a year to year 3.1 to 3.3 guy.
I"m really not sure how Drew Smyly even got put in there with two guys who have TOR potential. If Castro gets moved for Drew Smyly type talent then I'm done with this team.
I really don't hate this for the Red Sox. I figured he was a good bet for 6/110 in FA so they pay a bit more annually to not have to deal with the health risk in the last two years.
