Your post is full of analytic flaws and largely missing the point of the bigger picture. Rosario has already accomplished much more at this level than you care to give him credit for. Where to start? And I promise to be spin-free. And do you actually read the posts before responding? You and I are on the same page, my basic thrust is to point out that, because out of overriding necessity and urgency, Rosario's potentially fastest path to the majors may very well be to forestall the 2nd base experiment and see if he can go back to his natural position and be a possible alternative in CF, possibly beginning as soon as April 1, 2015. This is about avoiding the more likely possibility of failure at 2nd and seeing if he can dust off the rust from his layoff to determine how close he might be to hacking it at the plate while holding down the CF spot for the next year or so, at the least. Meanwhile back to the facts. In scanning the 2013 Eastern League results, Rosario is the only player 21 years of age, unless you go well down the list of Eastern Leaguers, who mostly all are far below his averages. The league age average is 24.5 , BTW. "Rosario was an average hitter in New Britain." Well, no, unless you say that among players with, and more than, Rosario's 40th ranking place (among some 90 players w/ over 313+ PAs) with respect to OPS and wOBA are considered "average." How about the true 2013 EL "average hitter"? Eastern League 2013 average OPS .713 Eddie Rosario 2013 AA average OPS .742 And even that is an entirely inaccurate assessment of Rosario's hitting accomplishments, as he needs to be compared with his 2nd base peer group (tied for 5th place among 16 2nd basemen with 300+ PAs, and all 4 ahead of him are 1-3 years older). The Eastern League averages for 2nd Basemen in the EL (300+ PA): OPS .701 wOBA .322 Rosario's averages from the EL in 2013 (repeated yet again): OPS .742 wOBA .355 Obviously, these numbers would compare just as favorably to the CF peer group, as well, and Rosario would be expected to have the potential to better those numbers if he can dust off the rust.
