"He (Bob Turley) was no herky-jerky tangle of arms and legs like
Dizzy Dean or Cleveland's fireballing
Bob Feller, with whose fastball his was sometimes compared. Like the great
Walter Johnson, he pitched with practically no windup, and had a remarkably smooth delivery for his 6-foot-2, 215-pound frame. He had a curve, a slider and a change-up, but the fastball was his magic. To a batter's naked, unflinching eye, it was an intimidating marvel to behold: the ball perfectly hidden as Turley looked in for the sign, paused to inspect the crowd, and let fly — an incoming rocket, a white blur barely visible for just over four-tenths of a second, and then — smack! — gone into the catcher’s mitt. 'Man!'
Roy Campanella, the Brooklyn Dodgers’ catcher, exclaimed after Turley struck him out three times in succession in a 1956 game. 'When you see me take three swings at three fastballs and not even foul tip one, the fellow throwing 'em must have something. Maybe he was using a little gun to fire that ball up there.'" - Sportswriter Robert D. McFadden in The New York Times (03/30/2013, 'Bob Turley, Pitcher With a Blazing Fastball, Dies at 82',
