Sports Illustrated: Greatest Covers

Mark McGwire and Sammy Sosa stole the cover of Sports Illustrated when they both made history in 1998. The players battled each other in a home run race to beat New York Yankees right fielder Roger Maris' record. Dubbed the Babe Ruth of the 1990s, St. Louis Cardinals first baseman McGwire made 70 single season home runs. Sammy Sosa, right fielder for the Chicago cubs, hit 66 home runs and was named the National League's Most Valuable Player. (Courtesy Sports Illustrated)
