Strahm will start Wednesday's series finale at Cincinnati, Kevin Acee of The San Diego Union-Tribune reports.
Strahm began the season in the starting rotation but has been working in relief since the All-Star break, so he's likely to have a limited workload Wednesday in what amounts to a bullpen day for the Padres. The 27-year-old has a 4.24 ERA and 1.12 WHIP in 14 outings since transitioning to the bullpen, though five of the eight runs he's allowed came during one outing.
