Guardians manager Stephen Vogt said Friday that Hoskins (back) has begun a swing progression program, MLB.com reports.
Hoskins still has time to make it back from the injured list before the end of the regular season, though he'll need to take live at-bats in simulated games and/or head out on a minor-league rehab assignment prior to being activated. Once he rejoins the Guardians, Hoskins will likely occupy the short side of a platoon at first base with Nathaniel Lowe.
