The Boston Red Sox have acquired right-hander Sonny Gray from the St. Louis Cardinals. The Cardinals will receive righty Richard Fitts and prospect Brandon Clarke. Gray went 14-8 with a 4.28 ERA for the Cardinals last season. In a 13-year career with five teams, he is 125-102 with a 3.58 ERA and three All-Star appearances. Fitts turns 26 next month. Gray gives the Red Sox a dependable option behind ace Garrett Crochet to take some of the pressure off the rest of the rotation.
