The population of third basemen in Major League Baseball is talented and getting increasingly young, and with the promotion of Manny Machado and impending ascension of top prospects Anthony Rendon, Nick Castellanos and Mike Olt (if he stays at 3B), the position is getting deeper and becoming even younger..
With that said, it should be understood the position has several question marks among the top echelon of players (ie, health issues, consistency issues), so in consideration of the depth of the position it may be advisable to wait until the middle rounds to make a selection if you do not get one of the top three or four options.
Of course, even in the middle rounds there will be some questions that attach to your selection, but if you’re going to select a third baseman with some questions it would be better to gamble with a fifteenth round pick than a fourth or fifth round pick.
(NOTE: Hanley Ramirez is included among the shortstops, as opposed to the third basemen)
