Manager Dave Roberts said Gonsolin (shoulder) will throw a fastball-only bullpen session Thursday, Juan Toribio of MLB.com reports.
If the Thursday session goes well, Gonsolin figures to incorporate off-speed pitches into his bullpen work and ultimately progress to facing live batters. Assuming he requires a minor-league rehab assignment, the righty should be back with the Dodgers near the end of August, if not a bit later.
