Bouncing back from a disappointing AA record, a .405 OBP, 130 OPS+ and 11 SBs in 14 attempts (counting the All Star game) is nothing to so easily dismiss as "not much." Given all #s are SSS, his AFL ISO of .044 is so out of line with his AA ISO of .158,, plus his minor league career ISO number of .197, I have to think the precipitous drop in power was a conscious decision on Rosario's part to change his approach for the league, and is not likely to reflect his power numbers too much going forward. The two sets of eyeballs on record on TD have said his defense has been good, and he's been a very good OFer coming up through the system. Back to his offensive prospects for 2015, with all of the plate protection in the batting order he will have at Chattanooga, plus the very hitter-friendly "Launching Pad" ballpark there , I think there's an excellent chance that he can build on this AFL experience, and be a candidate for call-up no later than next June.
