Lutz is an easy pick here, as he's going to put up monster numbers in Bakersfield.
As a darkhorse, how about Juan Perez (36)? He plays SS now and profiles to stick either there or at 2B. He hits LH, often, and with pop. He walks a decent amount (lifetime 400 OBP) and doesn't K all that much (a 26:39 BB:K ratio in half a season of ABs is solid). He also steals some bases (17 of 21 for his career).
Career numbers (55 GP, 250+ ABs): .318/ .400/ .502/ .902
He's starting in Dayton this season and is a year under appropriate level, so he's got a little cushion. If his stick stays solid (an 800 OPS will do it, IMO), he'll rocket up the Red pipeline charts.
As for pitcher, I'll go with Radhames Quezada (38). He's pitching in Dayton (which should allow him the best opportunity outside of Pensacola to put up good numbers. He figured out how to K guys last season (more than 10 per game). His walks are a little high, but, with what appears to be a decent defense behind him, his ERA will likely be low enough that many will take a shine to him. His stuff is reportedly good (a 75/80 fastball? Yes, please.) Too, he's right at level appropriate age (21) and has a fairly good track record behind him.
