Chicago Cubs activate C Miguel Montero from DL

The Chicago Cubs activated catcher Miguel Montero from the disabled list and started Saturday's game against the visiting Pittsburgh Pirates.

To make room for Montero on the 25-man roster, the club designated outfielder Ryan Kalish for assignment. Kalish is 2-for-7 with two runs driven in for the Cubs this season.

Montero was out with lower back tightness since April 25. In three rehab games with Triple-A Iowa, he went 2-for-10 over three games.

Heading into Saturday's contest, Montero is batting .208 with a home run and six RBIs in 48 at-bats.
