Based on what? His experience? He has roughly 1,900 professional AB's. Weeks has roughly 2,100. Braun has around 1,500. His age? Jose Reyes was barely 20 when he first came up. That he's never played above AA? Well neither did Hanley Ramirez, whose AA numbers at age 21 were pedestrian compared to Escobar's. What do these other guys have to do with Escobar? He's a different player. He's not MLB-ready, or he'd have been called up ahead of Iribarren. I don't know why his most recent 270 AB are supposed to be trusted moreso than his previous work... oh wait, yes I do -- it's happened more recently, therefore, it is his talent level. Nevermind the fact that Escobar has basically the same BA-reliant OBP as he always has, and would not be able to hit the .325+ he'd need to keep his OBP at or over .350 at MLB. Also, we could overlook the .373 BABIP for Alcides, but that doesn't seem very wise to me. Escobar's defense is great, but it doesn't mean he's MLB-ready because he's hit .333 against AA pitching (with an obscene BABIP). Heck, Ramirez is a perfect example of that. His last season in the minors, the aforementioned AA-stint, he put up .271/.335/.385/.720. The next season his MLB line was .292/.353/.480/.833. Maybe just maybe the scouting can tell us some things the numbers don't.
