One of the more quietly gratifying developments of 2013 for the Dodgers' front office was the emergence of some homegrown relief pitchers.Paco Rodriguez was among the Dodgers' top two or three relievers until a heavy workload took its toll in September. Chris Withrow was a viable late-inning alternative by the end of the season. Jose Dominguez, another hard thrower, dominated in the minor leagues and gave the Dodgers some useful July innings before his season got shut down by a strained left quadriceps.
