May 21 in Tigers and mlb history:
1907: National League president Harry Pulliam dismisses the Opening Day protests of Pittsburgh manager Fred Clarke over Roger Bresnahan's shin guards. As yet, Bresnahan is the only catcher using them.
1920 - Hughie Jennings manages his 2,000th game in the majors, all with the Tigers.
1923 - Formal transfer of T.L. Huston's interest in the Yankees to Jake Ruppert is completed for $1.5 million. Ten days later, Ruppert buys two more sets of uniforms so his players can wear a clean outfit every day, an unprecedented move.
1930 - Babe Ruth hits three consecutive home runs in the first game of a doubleheader against the A's, then batting against Jack Quinn in the 9th, Ruth decides to hit right-handed. After two strikes, he switches to lefty but strikes out. This is the first of two career 3-homer games for the Babe.
1940: Jimmie Foxx hits a grand slam for the second day in a row against Detroit in an 11 - 8 Red Sox win. Only Babe Ruth, twice, and Bill Dickey have slammed in consecutive days in the American League. Ted Williams, Bobby Doerr and Doc Cramer also homer for Boston. Hank Greenberg and Rudy York homer for the Bengals, while Wally Moses has a pair of triples and two singles.
1943 - Hal Newhouser endures his longest outing: 13 IP, 9 H, 1 R, 1 ER, 5 BB, 10 K.
1947 - Joe DiMaggio and five other Yankees are slapped with $100 fines for not fulfilling contract requirements to do promotional duties for the Bronx Bombers.
1957: Boston baseball writers reaffirm their decision to bar women from the press box and refuse to allow Doris O'Donnell, a Cleveland feature writer traveling with the Indians, to sit in the Fenway Park press area.
1957 - Jim Bunning has his longest career outing: 13 IP, 10 H, 1 R, 1 ER, 2 BB, 11 K, but it results in a no-decision as his Tigers prevail 2-1, over the Orioles in 16 innings.
1959 - Despite growing pressure to expand, major league owners, at a meeting at John Galbreath's farm in Ohio, decline the option to add new teams to the existing American and National Leagues. Given there are no plans for expansion, Commissioner Ford Frick will announce at a later date that Major League Baseball will "favorably consider an application for major league status within the present baseball structure by an acceptable group of eight clubs which would qualify under ten specifications."
1967: Earl Wilson gives Detroit its third straight win over the Yankees, 9 - 4. Mickey Mantle hits his 5th homer in six games but it's not enough for Whitey Ford, who appears in his last major league game.
2006 - Tiger reliever Todd Jones records his 155th save as a Tiger, breaking the franchise mark held by Mike Henneman.
