Marchan (hamstring) played in a simulated game Friday, Todd Zolecki of MLB.com reports.
J.T. Realmuto's fractured thumb could in theory give Marchan a chance to break camp as Andrew Knapp's backup, but it doesn't look as though that's going to happen. Realmuto appears to be on roughly the same schedule as Marchan, as he played in the same simulated game Friday, so there probably won't be a window where Marchan is healthy but Realmuto is still hurt.
