They're pressing and swinging at too many bad pitches, just being disciplined will make a big difference - Castellanos has fallen off b/c he's chasing that low and away breaking ball again, for example. I don't know if this is Long's weak spot as a coach or the team feels like they have to be as good as they were in the post-season and are over anxious.
Caves may get a look soon, SSS but he's having a ridiculous start in Lehigh, yes, he's been a career AAA plus guy, but when you hit that well, it's worth seeing if he's a late bloomer. Though Clemons is putting up a roadblock.
You don't know which kid will emerge, which is why good farm systems have lots of prospects and a few break out, bad farm systems have a few and you cross your fingers and hope to get lucky. But right now, Clearwater clearly is the best talent in the system, Jersey OK, and AA and AAA are primarily over age players and RPs. Think of the difference one young SP like Ranger a year ago would make, but they had all their eggs in the Painter basket.
