Pirates GM Ben Cherington said that Endy Rodríguez (glute) and Spencer Horwitz (hamstring) are “progressing well” and could start rehab assignments in 7-10 days.
Both players have been out for the majority of July, so they will likely need at least a week of rehab games before rejoining the Pirates. That means it might be early August when we see both of them back in MLB games.
