10 top prospects I would call up now

Even with the minor league season ending, the education of some top prospects will continue. Whether their big league clubs are in the pennant race or looking toward next year, the opportunity to learn at the big league level exists -- if they get called up. Of course, because of concerns about roster limits, service time and starting arbitration and free-agent clocks, some of these clubs won't promote the players even though they deserve it. But considering the success these 10 players have had this season as well as the impact they could have on their teams, it's time to bring them up.

Billy Hamilton, SS

Hamilton broke Vince Coleman’s pro baseball record of 145 stolen bases in a single season last week. He’s got 149 and counting between high Class A and Double-A. Despite that, the Reds are leaning away from bringing up Hamilton due to roster and service-time issues. And even if he is brought up, he probably won’t get a chance to play much in the final month of the season with the Reds in the heat of a pennant race. However, a call-up before Aug. 31 is important so that he is postseason-eligible.
