Bats are extremely important to maximize in your format. Go six bats (Hosmer, Jennings, Lawrie) with the keepers, and let someone else worry about Wainwright. TJ is now a fairly proven procedure, true, but Wainwright isn't a young guy despite his relative lack of MLB experience. Also, his best pitches historically, on a per-pitch value basis, are curveball/slider...not the most reassuring for a guy coming off TJ. There's probably a lot of pessimism regarding him, anyhow, that would make him easier to acquirer in the redraft than the bats you'd be keeping.
