Most minor league attention is paid to guys at the highest levels -- someone who might come up even before September, such as a Domonic Brown or a Buster Posey. The minor leagues are (obviously) multi-tiered. Here's a look at 10 guys at the lowest levels who could eventually blossom into the next Brown or Posey -- in two years or so.

Oswaldo Arcia, OF, Minnesota Twins (Rookie-level Elizabethton):
A 19-year-old Venezuela, Arcia has been dominating the Appalachian League. He leads the circuit in home runs, RBIs, hits and slugging and is second in batting. His line of .392/.434/.773 (BA/OBP/SLG) in 44 games says everything you need to know about his performance, and his scouting reports are almost as impressive. He generates tremendous raw power with a combination of bat speed and strength that is rarely seen in players so young. He's played some center this year but will be a right fielder down the road. If there's a problem, it's this: He's a very aggressive hitter. That could lead to issues as he continues to develop. For now, though, the reports are all good.
