"Cahill will come off the disabled list to make his first start since April 26, 2015, when he was with the Atlanta Braves. The 28-year-old Cahill, who has a 3.07 ERA in 41 innings out of the Cubs’ bullpen, landed on the disabled list July 15 (retroactive to July 9) with patellar tendinitis in his right knee.
Over six minor league rehab games — all starts — with Triple-A Iowa, Cahill posted a 4.58 ERA with 12 walks, 25 strikeouts and three home runs allowed over 19 2/3 innings. His longest minor league outing lasted four innings, so Maddon said he’ll ride Cahill for as long as he can and figure out the rest after. Left-hander Mike Montgomery could be an option to pick up some innings if Cahill has an abbreviated outing Tuesday. "
The guy pitched well. It happens. His minor league stats far from stellar.
