Martinez (ribs) will throw live batting practice Saturday, Mark Sheldon of MLB.com reports.
Martinez's scheduled outing Thursday was pushed back to Saturday due to a rib injury, but it appears the 33-year-old right-hander will work on the practice field instead. Martinez has previously said that he doesn't feel any discomfort while on the mound, and the Reds are confident he will be ready to go by Opening Day.
