For more than a century, baseball has been considered America's favorite pastime. References to playing baseball in America go back to the late 1700s and professional leagues were started in the late 1800s (baseball-reference.com). Since then, thousands of games-have been played and player performance (statistics) has been recorded. The most celebrated of those statistics have traditionally been home runs, runs batted in, and batting average—the three prongs of the lauded triple crown. Others like hits, walks, on base percentage and so on were recorded but often not valued to the same extent.
