If rosters hadn't just expanded at the start of September, Cubs first baseman Anthony Rizzo would probably be on the disabled list with a back strain, the team announced Tuesday.
Rizzo had an MRI taken on his back which showed a mild lower back strain, an injury that has already cost him eight games. If the team was still restricted to a 25-man roster, Rizzo would have already been placed on the disabled list. He will try to rehab the injury while remaining active at this point, and the team is not considering shutting him down for the final month.
