The Rangers revealed Thursday that Yu Darvish's back issue has subsided and the right-hander should have no problems with his offseason workouts. Darvish dealt with a back issue for the final two months of the season, but a little rest has apparently knocked the injury out. The 27-year-old right-hander is coming off a superb 2013 campaign that saw him put up a 2.83 ERA with a league-leading 277 strikeouts across 209 2/3 frames.
