Diamondbacks general manager Dave Stewart indicated that the team is targeting June 4 for the return of pitcher Patrick Corbin, according to FoxSportsArizona.com.
Corbin missed all of the 2014 season and has yet to pitch in a big league game this year, as he is recovering from Tommy John surgery. The left-hander was an All-Star in 2013, finishing with a 14-8 record, 178 strikeouts and a 3.41 ERA in over 200 innings pitched.
