Hamels (oblique) will throw a bullpen session Friday, and if all goes well, he will likely start Monday against the Indians, Evan Grant of The Dallas Morning News reports.
The lefty built up to 81 pitches during his rehab start Wednesday with Double-A Frisco, and he now faces just one final hurdle on the road back from an oblique strain. Hamels turned in a 3.03 ERA in five starts before going down with the injury, but a dramatic decline in strikeout rate (4.1 K/9) and swinging-strike rate, and an uptick in hard contact against, suggest he was overachieving to a significant extent.
