Liberatore is expected to be piggybacked by Hunter Dobbins in Monday's start versus the Cubs, Jeff Jones of the Belleville News-Democrat reports.
The opposition is slashing .358/.463/.627 off Liberatore the third time through the batting order, so the southpaw will likely be allowed to face the lineup just twice before turning things over to Dobbins. Liberatore has collected a 5.18 ERA, 1.52 WHIP and 95:38 K:BB over 99 innings covering 20 starts for St. Louis this season.
