McCann was Detroit's top pick out of Arkansas two years ago in the First-Year Player Draft and split last season between Erie and Class A Lakeland. He threw out 49 of 113 would-be basestealers for a 43 percent caught-stealing rate, but struggled to make the jump at the plate, batting just .200 at Erie after hitting .288 in A-ball.
His offense this year has been a revelation of sorts, with a .288 average and a .703 OPS to go with 15 doubles, three home runs and 36 RBIs. One American League scout who scouted the SeaWolves recently said McCann has gotten stronger and has raw power potential to go with average.
Defensively, manager Jim Leyland said, "he can catch and throw in the big leagues right now."
McCann is the Tigers' 11th-ranked prospect, according to MLB.com.
