Walter Johnson had incredibly long arms. No wonder he generated so much speed on his fastball.
Yes. That's what I've always thought, as well. Shirley Povich, who covered Johnson from 1924, described Johnson as having a whip-like motion. Hank Thomas, Walter's grandson and author of the great biography, says that Johnson also had and used a curve-ball. In Game 7, 1924, when Johnson pitched the last four inning (5 K's) on short rest, a couple of the strikeouts were on Johnson's curve. He didn't just over-power hitters...but the combination must have been tough!
