are there any good major leaguers currently on a minor league roster that would be worth a look for the future? i ask because my league has a minor league draft but for simplicity, any player that is currently on a minor league roster can be drafted. currently i have bj upton, justin upton, cole hamels, jeff mathis, and king felix. (again for simplicity, players can remain on the minor league roster until the owner calls them up.) also, will a player like howie kendrick be more valuable than hamels or mathis? thanks.

Kendrick is a ways more valuable then both Hamels and Mathis. Your other 3 minors are real good, but I would look to improve on Hamels and Mathis, with Kendrick being at the top of my lists.
