The Cubs have yet to decide how they'll fill the two vacancies in the rotation created by Friday's trade of Jeff Samardzija and Jason Hammel to the A's. Jake Arrieta, Travis Wood and Edwin Jackson will start the final three games before the All-Star break in a three-game series at Wrigley Field against the Atlanta Braves.
Hendricks was 10-5 with a 3.59 ERA in 17 starts at Triple-A Iowa. He is one option to move into the rotation, as is right-hander Dan Straily, who was acquired in the deal with Oakland.
