Greene worked on adding a curveball to his repertoire during the offseason, C. Trent Rosecrans of The Athletic reports.
Greene thew mostly his fastball (54.4 percent) and slider (40.3 percent) last season while occasionally mixing in a changeup (5.3 percent). The numbers were similar to 2022. "It's exciting," Greene said Sunday about the new pitch. "(I'll) continue to refine it and work on it, but looking forward to being able to have a good offering this season." Cincinnati pitching coach Derek Johnson said Greene needed a slower pitch, which will make his fastball play better. How much Greene throws the curve, which is in the low-80s this spring, will depend on how it looks against live batters during Cactus League games. The 24-year-old right-hander, who is expected to lead the Reds' rotation, has not thrown more than 125.2 innings in either of his first two seasons in the majors.
