Greg Halman, OF, Seattle Mariners

It has been a tumultuous ride through prospect-hood for Halman, once considered one of the game's top youngsters. He's your classic exceptional-athlete-who-has-a-lot-to-learn-about-baseball ... player. His game has been compared to some of the best players in that mold from the past couple of generations, though.

Halman has a lifetime .246 average on the farm and hit only .243 this year at Triple-A Tacoma. However, he smoked 33 homers, a career high, but not far off his previous highs. He stole 15 bases and has stolen more than 30 before, but raw ability won't net him that many in the bigs without improvement.

Seattle has been plugging Halman into the lineup in the season's final days. He collected his first big league hit a few days ago ... and that's it, in 17 at-bats. However, he's only 23. If your league allows for long-term investments, this one could still be a great find.
