Cubs right-hander Jason Hammel is officially set to start Tuesday's game against the Reds. Hammel left his last start after one inning on July 8 with a mild hamstring strain, and hasn't pitched since. But an MRI came back clean and after a throwing a side session last week, Hammel was given the green light for Tuesday. 

Hammel is in the midst of a strong stretch right now, posting a 3.25 ERA over his last five starts (excluding the July 8 game).
