Hamels (oblique) is set to throw another bullpen session Saturday with a batting practice session coming next week, Jeff Wilson of the Fort Worth Star-Telegram reports.
Hamels threw 21 pitches during his previous bullpen this past Sunday, and will likely go a bit longer during his second session since heading to the disabled list in early May. The southpaw is progressing nicely and could be able to return in the beginning of July, barring any setbacks.
