November 20 in Tigers and mlb history:
1884 - The National League agrees to allow overhand pitching, but rules that pitchers must keep both feet on the ground throughout their pitching motion in order to reduce the velocity of their pitches. They still must throw the ball at the height requested by the batter. In addition, teams are now required to supply a separate bench for each club at their park to limit inter-team fraternization.
1888 - The Joint Rules Committee reduces the number of balls for a walk from five to four, establishing the four balls/three strikes count that remains in effect to this day. It also eliminates an out on a foul tip if the catcher catches it within 10 feet of home plate.
1934: 17-year-old pitcher Eiji Sawamura gives up one hit, a home run to Lou Gehrig, as the touring major league All-Stars win in Japan, 1 - 0. At one point, Sawamura strikes out four future Hall of Famers in a row: Charlie Gehringer, Babe Ruth, Jimmie Foxx, and Gehrig.
1957: The Detroit Tigers and Kansas City Athletics execute a 13-player trade. Among the players involved are second baseman Billy Martin, outfielder Gus Zernial and pitcher Mickey McDermott, who are headed to Detroit. The Athletics acquire pitcher Duke Maas, catcher Henry House, and outfielders Bill Tuttle and Jim Small.
1958 - The Detroit Tigers trade infielder Billy Martin and starter Al Cicotte to the Cleveland Indians for relievers Ray Narleski and Don Mossi and shortstop Ossie Alvarez.
