Beeler optioned to Triple-A Iowa; Hendricks called up

CINCINNATI -- The Cubs optioned right-handed pitcher Dallas Beeler to Triple-A Iowa on Thursday and selected right-hander Kyle Hendricks from the Minor League team. Hendricks was to make his Major League debut Thursday in the series finale against the Cincinnati Reds.

Beeler gave up four runs over five innings in the Cubs' 4-1 loss to the Reds on Wednesday in his second big league start.

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.
