Dobbins is expected to piggyback Matthew Liberatore in Monday's game against the Cubs, Jeff Jones of the Belleville News-Democrat reports.
It had seemed as though Dobbins would draw another spot start this week, but instead he will follow Liberatore out of the bullpen in a tandem outing Monday. Dobbins tossed six shutout frames in a start last week against the Angels and holds a 3.18 ERA, 1.31 WHIP and 28:10 K:BB across 28.1 innings with St. Louis this season. The righty could receive regular turns in the Cardinals' rotation soon if the club trades Dustin May at the deadline.
