Cubs' Trevor Cahill: Starting first game of Tuesday's doubleheader

Cahill (knee) will start the first game of Tuesday's doubleheader against Milwaukee, ESPN.com reports.

Analysis:

Cahill's start could be a short one, as he never topped four innings during an extended six-game rehab assignment with Triple-A Iowa, throwing between 36 and 68 pitches in his final three starts. After Tuesday, he'll likely be used as a long reliever and could be the first choice for spot starts.
