Darvish, 28, missed the last seven weeks of the 2014 season due to right elbow inflammation. He reportedly entered spring training in good health. 

The Japanese ace has made the All-Star team in all three of his major league seasons, and led the league with 277 strikeouts in 2013. He went 10-7 in 22 starts for the Rangers last season, with a 3.06 ERA and 182 strikeouts in 144.1 innings.
