These players were power hitters that knocked in runs in large clusters. They were tough, hard-nosed competitiors, not little singles-hitters. I would be interested to know how many bunts these guys laid down in their careers. I would think very few.
Hank Greenberg, a two-time American League MVP for the Tigers who hit 58 home runs in 1938. He hit 331 homers over his 13-year career as a first baseman and outfielder, despite missing several years while in the military during World War II.
Mickey Mantle, the Yankees' switch-hitter who hit 536 home runs over nearly two decades as one of the game's biggest stars. He was AL MVP three times.
Roy Campanella, the Brooklyn Dodger who hit 242 home runs during his 10-year career, cut short by a car accident. A catcher in five World Series, he was named National League MVP three times.
Mel Ott, remembered for a powerful high-leg-kick batting stance. Ott, an outfielder, distinguished himself with the New York Giants for 22 seasons and was the first NL player to hit 500 home runs. Ott finished with 511 homers, then became a Tigers broadcaster in 1956-58.
Speaking of great baseball sluggers, the Louisville Slugger Bat Company has a great web site with all kinds of information about the most famous bats in the world. It's www.sluggermuseum.com. I've also heard that if you're ever in Kentucky (heaven help you!), they have a great tour at the Louisville Slugger Factory & Museum.
