May 24 – Bill Bradley of the Cleveland Bronchos sets an American league record by homering in his fourth consecutive game, a record not matched until Babe Ruth does it on June 25, 1918.[1]
June 2 – The Cleveland Bronchos commit 6 errors in one inning against the Baltimore Orioles. It will be the most errors by a team in one inning for the entire 20th century.
June 15 – Future major leaguer Nig Clarke goes 8–8, all home runs, as his Corsicana team blasts Texarkana 51–3 in a Texas League game. Corsicana collects 53 hits, including 21 homers, in playing the game in a park where right field is only 210' from home plate.
June 30 – The Cleveland Bronchos becomes the first American League team to hit three consecutive home runs in one inning, as Nap Lajoie, Charlie Hickman and Bill Bradley connect in the sixth off St. Louis Browns pitcher Jack Harper, with all the homers landing in the left field bleachers at St. Louis. The last two come on the first pitch thrown, while Cleveland wins the game 17–2. The feat was last done in the National League on May 10, 1894.
July 8 – John McGraw signs a contract to become the manager of the New York Giants. McGraw will remain as the Giants manager for the next 30 years, winning ten National League pennants and three World Series.
July 8 – In his first game for the Philadelphia Athletics, Danny Murphy arrives late in the second inning and is immediately put in the game. He proceeds to go 6-for-6 at the plate, which includes a grand slam off of Cy Young, and handles 12 chances without committing an error at second base.
July 17 – The Baltimore Orioles, due to an exodus of players to the Giants, are left with only five available players for a game against the St. Louis Browns. The Orioles are forced to forfeit the contest, and the American League takes control of the team for the remainder of the season: the Orioles ultimately fold after the season.
August 13 – Harry Davis of the Philadelphia Athletics steals second base with teammate Dave Fultz on third in an attempt to score Fultz. When he draws no throw, Davis then steals back to first base on the next pitch. He then steals second again, this time drawing the throw, scoring Fultz.
August 14 – Tommy Leach of the Pittsburgh Pirates hit only 63 home runs over the fence in a career of over 2,100 games. On this day, however, he does it twice against the Boston Beaneaters. Leach will go on to win the National League home run crown in 1902 with 6.
