I was offered Aarong Harang and Edgar Renteria for Roy Halladay. I do need some help at SS/MI so Renteria is very attractive because of his OBP and Runs scored. Harang is an upgrade in K's but that's about it although not too much of a dropoff from Halladay.
That said I'm concerned what type of second half Harang will turn in. Last season he struck out batters at 50% the rate he did in the first half. Will he revert back?
