Wheeler is the scheduled starter for Saturday's game against the Cardinals, Marc Carig of Newsday reports.
With a rainout pushing Jacob deGrom into Friday's series opener, the team will simply move Wheeler into the regular rotation spot of Rafael Montero. The 27-year-old righty hasn't made it through four innings over his last three outings and only recently returned from a DL stint due to biceps tendinitis, so he'll be looking for a strong bounce-back game prior to the upcoming All-Star break.
