If all goes well, today’s Spring Training action will feature Zack Greinke’s return to the mound as the Dodgers take on the D-backs in Glendale, Ariz. Greinke, who sustained a mild calf strain in his first Cactus League start on Feb. 27, participated in pitchers’ fielding practice and other drills Tuesday, and he is penciled in to start Los Angeles’ 4:05 p.m. ET contest, which streams live on MLB.TV.
