David Cone was famous for his splitter, used most often in the middle and later part of his career. A major strikeout pitch for him, Cone would throw it hard like a fastball to get swinging strikes. He also was very effective in throwing it slower, using it as a changeup to throw off hitters' timing. Jack Morris learned the pitch from Roger Craig in 1980, and it became an effective "out" pitch for the Tigers' hurler. Mike Scott also learned the pitch from Roger Craig after the 1984 season, and it turned his career around. He won the 1986 NL Cy Young award and posted a league-leading 306 strikeouts. Randy Johnson developed a splitter later in his career after losing some of his extremely high fastball velocity.
