DENVER (AP) — The Colorado Rockies have recalled left-hander Drew Pomeranz from Double-A Tulsa and optioned infielder Josh Rutledge to Triple-A Colorado Springs.

Pomeranz will start Monday’s series opener against the Miami Marlins.

Pomeranz will be making his second stint with the Rockies after beginning the year at Triple-A Colorado Springs. He was recalled on June 30 and was 0-3 with an 8.76 ERA in three starts before being optioned on July 12 to Double-A Tulsa.

The centerpiece to the 2011 trade of Ubaldo Jimenez to Cleveland, Pomeranz has struggled in the majors. He is 4-13 with a 5.37 ERA in 29 career starts.

Rutledge is hitting .211 with six home runs in 67 games this season.
