Hamels (oblique) is not expected to return until the second week of July at the earliest, Evan Grant of The Dallas Morning News reports.
The veteran southpaw fired a 55-pitch bullpen session Saturday, although he has yet to face live hitters. Hamels seems to still be progressing well, but the Rangers appear to be taking the cautious approach with his return, likely meaning that he won't be back in the rotation until after the All-Star break.
