The Sox picked up Bryan Corey from the Rangers for a crappy minor leaguer today. In limited time, Corey has been pretty decent for Texas, posting 13 strikeouts in 17.1 innings and a 2.60 ERA. His WHIP is a little high (1.33) to expect an ERA that low, but this is still a good pickup. Corey's OPSA is .645, which is great, but his K/BB ratio is a little low at 1.63/1. Strangely, Corey has 2 career decisions (1-1), and they've both come at Fenway Park.
The Sox traded AA Portland pitcher Luis Mendoza, who had struggled in AA with a 1-5 record and 6.38 ERA in 9 starts.
I say any time you can trade a guy who's struggling at AA for a guy who has proven success in the majors, you do it. Well, most of the time anyway.
