Santillan (back) is scheduled to pitch a minor-league game Wednesday for the Reds in Arizona, Bobby Nightengale of The Cincinnati Enquirer reports.
This will be Santillan's first appearance of the spring -- albeit on the minor-league fields -- as he has been sidelined with a back strain that also saw him miss action during the 2022 campaign. The right-hander is hoping to be ready for his 2023 debut by mid-April, and barring unforeseen circumstances, he'll open the regular season on the injured list.
