Phillies: Five role players who could help the roster

Nick Castellanos
Nick Castellanos may quietly be one of the best hitters on the market this year playing for a Tigers team currently 15 games below .500 in a horrible division.
A former first round pick, Castellanos is hitting .305 with 15 home runs and 29 doubles for Detroit. His 2.1 WAR is better than Mike Moustakas, Kris Bryant, and DJ LeMahieu this season, proving his worth leading into the deadline.
Castellanos has played the majority of his career at third base, but he’s seen nearly 1,000 innings in the corner outfield spots, mostly this season.

Most importantly, he’s just 26 and entering his final year of salary arbitration. Locked into a team-friendly situation for another year, Castellanos could be a valuable piece for the Phillies moving forward as a bat off the bench or even a short-term starter at third if Maikel Franco is traded.
