Wang has had injury issues the past couple of years, and it really affected his performance in 2009. In 2007, his last full healthy year, though, look what he put up:
30 GS, 199.1 IP, 9 HR allowed, 2.7 BB/9, 4.7 K/9
While the low K rate is nothing to write home about, his ability to keep the ball in the park and in play is quite good.
But really, if you want a low-K guy who can get you through some innings, Wang would be a good pick, and he can potentially be a really good one. He's probably cheap because of the injuries, but he'd look good in the back of the rotation, and he would bring some nice variety with the strikeout guys Billingsley and Kershaw as well as Kuroda.

That would be fun, right?
