Liberatore (back) will pitch out of the bullpen for the Cardinals after he was reinstated from the 15-day injured list Monday, Jim Hayes of Bally Sports Midwest reports.
Liberatore will be available in relief beginning with Wednesday's game at Atlanta. The 23-year-old left-hander has struggled to a 6.12 ERA, 1.64 WHIP and 35:21 K:BB in 50 innings (11 starts, one relief appearance) this season at the major-league level and surrendered seven runs (six earned) on seven hits and 10 walks over 6.2 innings between his most recent two rehab starts at Triple-A Memphis. With Liberatore moving to the bullpen, Drew Rom will retain a spot in the St. Louis rotation as the team's fifth starter.
