It took a little time, but the light has clearly come on for this guy. It seems like he will be ready for Louisville by the end of this season, then fighting for a job with the Reds next season. If you look at where Brian McCann (another high school catcher) was in his fourth pro season at the AA level:
198 PA, 166 AB, 27 R, 44 H, 13 2B, 2 3B, 6 HR, 26 RBI, .265/.359/.476
Versus what Mesoraco is doing right now in AA in his fourth pro season:
127 PA, 113 AB, 29 R, 34 H, 9 2B, 1 3B, 9 HR, 21 RBI, .301/.354/.637
It compares pretty favorably. McCann was a year younger and was called up to Atlanta about midway through that season, never playing a game in AAA. Is there any reason to think that Mes won't be ready to play at the major league level next season?
