Hoyt Wilhelm's intriguing baseball career lasted two decades. A veteran of the Battle of the Bulge, the eight-time All-Star from Huntersville, North Carolina, was a standout for the New York Giants, Baltimore Orioles, Chicago White Sox and Atlanta Braves, though he did not reach the majors until he was nearly 30. He pitched a no-hitter as a starter, won as many as 15 games a season, was the first reliever to win more than 100 games and save more than 200, and broke Cy Young's record for most games on the mound. Along the way, he relied almost entirely on his baffling skill with a rare weapon of choice—the knuckleball. This first full-length biography covers the life and career of the first relief pitcher in the Hall of Fame.
