O'Malley made his major league debut for the Cubs on August 16, 2006, against the Houston Astros. He pitched eight innings, giving up five hits, six walks, two strikeouts and no runs in a 1-0 win. In his next start, he pitched four and two-thirds innings before leaving with a strained left elbow. He was activated from the disabled list on September 8, 2006.
In February 2008, O'Malley was signed by the Schaumburg Flyers of the independent Northern League, but before appearing in a game for them, he left to sign a minor league contract with the Chicago White Sox. He became a free agent at the end of the season.
On December 2, 2009, O'Malley was named the pitching coach for the Arizona League Rangers.
