Well, I was apparently wrong that no other team would want Eric Patterson, because not only did the Red Sox trade for him, but according to Susan Slusser, a few other teams were interested as well. Why, I have no idea, but hey, the A's got a not-so-horrible prospect, LHP Fabian Williamson in exchange. Williamson has fringy stuff and at 21 in high-A is on an average developmental curve. He had good numbers in low-A last season (2.42 ERA, 108 IP, 3 HR, 53 BB, 104 K) but was in a pitcher's league and did walk a lot of guys. In high-A this year, his walk rate has stayed the same but his K numbers have dipped (just 40 in 65.1 IP) and he now moves to the hitter-friendly California League. How he navigates that as well as the move up to AA will illustrate whether he has any kind of a future.
The odds are Williamson won't pan out, but just like with the Jake Fox deal, I would have been happy with anything in return for a non-factor like Patterson, and Williamson looks to be a decent prospect (John Sickels gave him a C, so pretty much a organization depth kind of a guy who occasionally turns into something), so I have to be happy with the deal.
