Fans of the San Diego Padres got their first glimpse of what Nick Castellanos could be if he breaks camp as a part of the big-league roster. Castellanos went 2-for-3 in San Diego’s 4-3 win over the Chicago White Sox on Tuesday and that included a double and a two-run home run off the bat of Castellanos. He was signed with the expectation that he would provide slug on offense and compete for time at first base and designated hitter. Castellanos is not a refined first baseman by any means, but he has not looked lost at the position as he tries to get used to having his feet back in the dirt after years in the outfield. If he can do what he did against the White Sox and continue to improve defensively, he could be this year’s Gavin Sheets for the Padres.
