I'm having second thoughs on MCab being as good as believed by the "linup protection doesn't matter" camp. Exhibit A.
Exibit B: It seems people are pretty high on Hermida and feel he'll provide decent OBP and/or protection for Cabrera. I think he's a good hitter, but he's coming straight from AA. I'm not sure he isn't a good flop candidate. Is he really in that class of hitter, like Vlade, who went from AA to success? Even A-Rod stopped in AAA, for 32 games, Helton for one and a half seasons, Bonds for 44 games and a more comparable hitter like Paul O'Neill played a good amount of AAA ball before coming to the bigs.
The small sample size of his MLB experience (47 PA) isn't enough to garuanteed him success. The only good pitchers he faced were Patterson (1/3, 1K, 0 BB), Myers (0/3, 3K, O BB) and Farnsworth (0/1, K, 1 BB).
I see a reasonable chance of Hermida flopping and Cabrera producing more like he did the in last 3 monts of last season than he did in his first three.
