Mike Trout.  3 hits today, a homer, double, plus a walk.  He's hitting .372.  Takes walks, showing good power.  Did I mention he can run (20 steals already).  And he's only 18.  He's the most exciting prospect we've had since...well, you know who I'm talking about.  And that player's struggles show why you can't expect too much out of any prospect.
