The Rule V draft occurs in a few weeks. There, teams can claim unprotected minor league players from other teams.
Under the draft rules, players signed at 19 or older are protected for three years, while players signed at 18 or younger are protected for four years. Thus, you have to be 22 to be selected. Players off the 40-man roster are eligible.
So, looking at the Phillies system, that means the most appealing players for Rule V are, initially (thanks, Phuture Phillies):
Brett Harker, RHP
Jeremy Slayden, OF
Clay Harris, IF
Pat Overholt, RHP
Once-eligible Carlos Carrasco was added to the 40-man roster. In my upcoming top 25 prospect list, you’ll find Slayden is among the considered. Of all prospects, he’s the most likely to be selected — a power-hitting fifth-outfielder type who can contribute to a major league team in 2009 (he hit a game-winning home run to put the AFL Mesa Solar Sox in the finals). Most prospect trackers agree on this. He’d have to spend an entire season on a team’s 25-man roster to be kept; otherwise, the Phils will have a chance to reclaim him.
