The ability of even Jeremy Guthrie to exploit the Os line shows you that they really miss a big lefty bat or two (e.g., Davis and Wieters). Even middling innings eating 5th starters reduce Steve Pearce to average (which tells you how good he's been overall that you can use the phrase "reduce to average" in describing Pearce). that stretch of Jones / Cruz / Pearce / Hardy is a lot less intimidating when facing a righty. There really is not a lefty bat you have to fear. Markakis is not a power threat, and De Aza brings neither OBP nor power this year.
