Ramos, who is not in Sunday's lineup against the Cardinals, has a tight hamstring and has been playing through plantar fasciitis, Alex Pavlovic of NBC Sports Bay Area reports.
Manager Bob Melvin said that Ramos could hit Sunday or start at designated hitter, but with nothing to play for, he'll likely get the finale off. Ramos had a breakout age-24 season, slashing .269/.322/.469 with 22 home runs and six steals in 518 plate appearances.
