Is miscast a bit, but there are a lot of really baaaaad LF's in baseball...Dr. D is not married to pretty D, but the suspicion here is that slow, "mechanical runner" Carp is going to be a legitimately poor defender in LF. So:..........Scenario 1: Carp comes up, finally provides the pleasant hitting surprise we needed out of our minors, and blasts away for a .550 (park-neutral) SLG or somesuch... in this event he is welcome to play LF for me...Scenario 2: Carp comes up and hits like Tino, against RHP's anyway... in which case he definitely DH's and Cust hits the road...In this event, the LF hole served as Carp's quirky chance to establish himself in the bigs generally...Scenario 3: Carp doesn't pan out... as Sully points out, you have lost absolutely nothing...Unless, of course, you're on the verge of a Kubel / Beltran type deal, back room.................Carp has now played exactly 161 games in 2010-11, with 44 home runs. In Cheney.If he could square the ball up at all, impossible to imagine him not banging some pitches into the RF seats here. They've got a *seasoned* hitting prospect going, one who's been in the bigs, one who's already made some adjustments.
