Mlodzinski is slated to pitch in bulk relief behind opening pitcher Mason Montgomery in Thursday's game against the Rockies in Pittsburgh, Colin Beazley of the Pittsburgh Post-Gazette reports.
Mlodzinski will work behind an opener for the second time this season, with the right-hander having previously followed Montgomery in an April 15 game against the Nationals. The arrangement didn't end up suppressing Mlodzinski's workload; in fact, the 27-year-old covered six innings in that game against Washington, matching his longest appearance of the season. Montgomery is likely to work just an inning or two before handing the ball over to Mlodzinski, who takes a 4.50 ERA and 1.45 WHIP into Thursday's contest.
