CHICAGO -- The Chicago Cubs placed right-handed pitcher Rafael Dolis on the disabled list with a forearm strain and selected the contract of reliever Blake Parker from Triple-A Iowa on Saturday, the team announced.

Dolis appeared in five games for Chicago this season, throwing five innings without giving up a run. Parker, 27, pitched in seven games last season for the Cubs, giving up three earned runs in six innings. In 16 appearances for Iowa this season he was 0-1 with a 2.04 ERA and seven saves. He was one of the last cut-downs near the end of spring training.

To make room for Parker on the Cubs' 40-man roster the team designated reliever Alex Burnett for assignment. Burnett was picked up off waivers from the Baltimore Orioles at the beginning of the week.

The Cubs play the Arizona Diamondbacks Saturday night at Wrigley Field. Parker will be in uniform for the game.
