This baseball's hurtling at you at 100mph according to American claims for famous "steamball" pitcher of the last decade, Bob Feller. ***** most of the leading US pitchers are suing ***** perimenting with it. ***** first tried the slider during Service games ***** the war and began to use it in serious baseball ***** he returned to the Indian in 1945. When an ***** injury in 1946 slowed down his once overpowering first ball he relied mainly on his exceptional curve and improved control. Last year he topped the American League with 22 winning games, which restored him to baseball's top pitching salary - 55,000 dollars. January 01, 1952. (Photo by Look Magazine).
