Thanks, zub.
What you've also got to consider is this isn't an OL, it's a single-season prog. My (very likely) first round opponent will have only 1 starting batter with a good walk rate (118 BB in 636 PA) -- most of his full-time batters have around 50-60 walks. And as Martinez doesn't give up the longball (that's at least one thing he's done well this season, so I know that's not broken) a few walks here are there shouldn't hurt us too much.
P.S. Your projected ERAs follow the same order as these pitchers' ERC#s -- RM 3.13, CW 3.18, GG 3.42, BV 3.67 and DW 3.90...
