Current Through 2013 Season

	Did you know that during the 1979 regular season two pitching brothers led the National League (first and only time in Major League history) in games won — Joe Niekro and Phil Niekro? Roger Clemens had the two furthest apart league leading seasons in games won going from 1987 then waiting until 1998 in the American League for another league leading total. In 1968 Denny McLain won thirty-one regular season games becoming the first pitcher since 1934 (Dizzy Dean of St. Louis) to win more than thirty regulation games in a single season.
