St. Louis, MO (SportsNetwork.com) - The St. Louis Cardinals have activated pitcher Kevin Siegrist off the 15-day disabled list.

Siegrist had been sidelined since late May because of a left forearm strain. He recently worked 4 2/3 scoreless innings over five appearances during a rehab assignment with Double-A Springfield.

The lefty was 1-1 with a 3.60 ERA and 27 strikeouts over 20 innings in 23 games for the Cardinals this season prior to his DL stint.

St. Louis optioned pitcher Nick Greenwood to Triple-A Memphis to open a roster spot for Siegrist. Greenwood was 1-1 with 4.74 ERA in nine games for the Cardinals since his recall last month, including two perfect innings during Tuesday's loss to Tampa Bay.
