Detroit Tigers third baseman Nick Castellanos isn’t quite a third baseman in ESPN standard fantasy formats yet, but it should happen soon. For those who keep wondering about the ESPN rules of eligibility, it takes 10 games in-season to add it, 20 from the previous year. Castellanos, an outfielder in his brief time in the majors last season, played his ninth game of this season at third base Thursday afternoon, contributing a single and a walk in a 7-5 win over the Cleveland Indians. Castellanos hasn’t hit much, but he will, and he’ll look better for fantasy owners with third base eligibility, which figures to arrive Friday night.
