The Cardinals recalled Liberatore from Triple-A Memphis on Monday.
It's been a busy three days for Liberatore. He was called up for his big-league debut Saturday before being optioned the next day, only to rejoin St. Louis one day later with Steven Matz (shoulder) landing on the injured list. It's unclear exactly how long Matz's absence will last, but Liberatore will get the chance to replace him in the rotation and should have at least a couple more starts to prove he belongs in the big leagues. His debut wasn't particularly good, as he allowed four runs in 4.2 innings against the lowly Pirates, but he's talented enough that there's reason to expect more going forward. According to Jeff Jones of the Belleville News-Democrat, Liberatore is scheduled to make his second start with the Cardinals next Saturday versus the Brewers in St. Louis.
