In our story about New York Yankees outfielder Gary Sheffield (Swinging Away, Oct. 11), we wrote that Sheffield, while with the Milwaukee Brewers, had "flattened" teammate Mark Knudson after the pitcher told writers that he didn't want the ball hit to Sheffield in the late innings. SI has subsequently learned that no punches were thrown between the two men, and, says Knudson, "there was never any sort of physical or even verbal confrontation between myself and Gary." Knudson also says that "never in my 12 years in professional baseball did I go to the media and criticize a teammate." SI regrets the error. --ED.
