The Reds placed Hayes on the 10-day injured list Friday with a lumbar bulging disc.
The third baseman's back has been an issue for years, and per C. Trent Rosecrans of The Athletic it has bothered him off and on this season. The plan is for Hayes to get healed up before reporting to the team's spring training complex in Arizona to initiate his rehab. It sounds like an injury that is likely to keep him out beyond 10 days, and the Reds could want him to find a groove at the plate on a rehab assignment before reinstating him. The 29-year-old is slashing an ugly .142/.195/.225 this season. Sal Stewart will likely continue handling the bulk of the workload at the hot corner in his absence, with Eugenio Suarez also an option once he comes off the IL.
