Most of Jer's list is just young players that are expected to break out, not really sleepers.
Burnitz is a good one, and I'd also say that Matos is a good one. You don't hear much about him, but he could be great.
A few of my own:
Richard Hidalgo (Unless he's traded to LA)
Also, some might say D'Angelo Jimenez, but I've heard so many people say he's a sleeper that the secret might be out.
