At this point, Rendon and Werth are kind of interchangeable in my mind offensively. I kind of prefer at the top of the order and Rendon lower, but it does not make much of a difference. I'm still a believer in batting your top OPS guys #2, #4, and #1, so I want Harper near the top, too. I'd kind of prefer Werth - harper - Desi - RZ - ALR - Rendon - Ramos - Span, but think this order is close to right.
Desi 3d because his OPS is good and SLG heavy, RZ 4th because he's a better OBP guy with good power.
