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.
