Cain (quadriceps) has resumed running and fielding but has yet to begin hitting, Tom Haudricourt of the Milwaukee Journal Sentinel reports.
Cain continues to deal with a quad issue that was initially described as "very minor," and the 34-year-old is making slow progress in his recovery. A timetable for his return to hitting isn't yet known, but it's fair to wonder whether he'll be able to ramp up in time for Opening Day -- Cain is not only entering his age-35 season, but he also opted out of the 2020 campaign after appearing in only five games.
