1st As noted in 1998 by historian John O’Malley, Washington’s George Keefe sets the ML record by walking 7 New York Giants in the 5th inning. The mark will be matched by Tony Mullane in 1894, and Bob Ewing in 1902.
2nd After a 5–1 loss to Louisville, the St. Louis Browns nearly go on a sit-down strike in support of teammate William “Yank” Robinson. Robinson had been suspended and fined after a shouting match with owner Chris Von der Ahe, and his indignant teammates had refused to go to Kansas City for their next series. At the last minute, the players board the train, but they would then drop 3 in a row to the Cowboys amid charges that they are losing on purpose. The Browns lose three in a row, 16-3, 16-9 and 18-12, when KC scores 11 in the final inning. St. Louis wins the final game of the series, 11-9. When the team returns to St. Louis, manager Comiskey placates Robinson and he rejoins the team for a May 7 game against Columbus.
Washington goes to 0-5 with a 16-3 loss to the New York Giants. George Gore hits a grand slam for the Gothams in the 9th inning off Hank O’Day.
4th Indianapolis’s Jerry Denny goes 6-for-6 with 4 singles, a double, and a 7th-inning grand slam to lead the Hoosiers over the Pittsburgh Alleghenies 17–12. The hits come against Jim Galvin and Harry Staley.
5th Brooklyn forfeits a game to the Athletics 9–0 when the unruly crowd at the Bridegrooms’ Sunday grounds in Ridgewood, Queens, overruns the field in the 6th inning with the visitors leading, 5–1.
6th With Robinson’s latest fine having been rescinded, the Browns (AA) win the final game of their series with Kansas City, 11–9. The winning runs come in the bottom of the 9th. A new rule for 1889 allows additional runs to score after the winning run in sudden death situations if the runners could score before the ball can be returned to the pitcher. This game demonstrates the problems with the rule, since the Brown’s Elton Chamberlin drove home the tying run on a hit through the second baseman’s legs and then circled the bases for a home run when the Cowboys left the field without chasing the ball down. The Browns were batting last since the home team chose to bat first, a prerogative that will stand till 1950 when the rules are codified.
7th Silver King is an easy winner as St. Louis (AA) drills Al Mays and Columbus, 21–0. Yank Robinson returns to action with a 4-for-6 day.
8th The new Olympic Park opens in Buffalo with a 6–2 Bison victory over Hamilton in an International association game. The opener is delayed slightly by the man barring the gate with a shotgun and demanding to be paid for work he had dome as a subcontractor during the park’s construction. Although its name will change over the years from Olympic Park to Buffalo Baseball Park, to Bison Stadium, and to Offerman Stadium, this site, at Michigan Avenue and Ferry Street, will remain the home of Bison baseball through 1960.
9th Ad Gumbert, a pitcher, plays LF and hits a 4th inning grand slam, off Pete Conway, to give Chicago a 7–6 win over Pittsburgh. Although he plays in just 41 games in 1889, Gumbert will hit 7 homers.
10th Arlie Latham goes 5-for-6 with a double and 2 homers to pace the Browns to a 15–6 win over Columbus. St. Louis leads the AA race with a 16–6 record. Brooklyn, the eventual chap, is in 4th place.
14th Pittsburgh suspends sore-armed pitchers Ed Morris and Pete Conway so the club won’t have to pay their salaries while they’re disabled. Morris will return to action June 8th, but Conway is through as a ballplayer because of his injury.
15th Brooklyn’s Dave Foutz connects for a 5th-inning grand slam, off Mike Smith ,as Brooklyn beats Cincinnati, 10-6.
16th It adds up. Called in from the outfield to face Phillie slugger Sam Thompson with the bases loaded in the 2nd inning, Ad Gumbert serves up a home run on the first pitch. Will Hutchison then returns to the box for Chicago and finishes the game, losing 16–12.
At American Park, Baltimore’s leadoff hitter Mike Griffin hits a homer and is matched by the Reds leadoff batter Bug Holliday. The Reds prevail, 4–2. Holliday, a rookie, will tie for the NL lead in homers with 19.
17th Spud Johnson hits a grand slam in the 7th, off Scott Stratton, as Columbus tops Louisville, 9-4.
19th Fire destroys most of the stand at Brooklyn’s Washington Park while the Bridegrooms are on a road trip. With young Charlie Ebbets in charge, rebuilding begins right away.
20th The Kansas City Cowboys, after choosing to bat first, score at least one run in every inning against Brooklyn, winning 18–12. Mickey Hughes is the losing pitcher, going the distance. The Cowboys become the 2nd team in AA history to score in all 9 innings, Columbus having done so on June 14, 1883. The feat has not yet been accomplished in the NL.
23rd Lou Bierbauer carries the Athletics to a 9–8 win with a 2-run homer and a grand slam, and scores the winning run after a 9th-inning single. The slam comes in the 7th off Silver King.
24th Willie Kuehne sets a new record by accepting 13 chances at 3B. Kuehne makes 3 putouts and 10 assists without an error, a ML record. His brilliant work enables Pittsburgh to best Washington, 9–7.
25th Phillie 2B Ed Delahanty suffers a broken collarbone when he slides into Cleveland 2B Cub Stricker in the 5th inning. Delahanty will be out of action until July 30th. Cleveland wins, 4-3.
At Columbus, umpire Fred Goldsmith ejects Dave Orr and then forfeits the game to the visiting Brooklyn (AA) team when Orr refuses to leave the field. The two teams, however, refuse to abide by the forfeit, and the game is eventually completed with a sub playing in Orr’s place. Brooklyn wins, 6–3.
27th Scott Stratton, who served up a grand slam 10 days ago, hits one of his own in the 7th for Louisville, off Lee Viau, but Cincinnati wins, 10-9.
28th The Reds take a 8-0 lead over visiting St. Louis but the Mound City men rally to tie the match at 12-12. Cincinnati finally wins, 13–12.
30th Brooklyn draws the largest crowd in AA history, 22,122, for the Bridegrooms’ afternoon game against the Browns. This may also be the largest standing-room crowd in history, since there were only 3000 seats erected in the 11 days since the fire at Washington Park. An additional 8,462 saw the morning game, as the teams split, the visitors winning the a.m. game, 8–4, and then losing in the afternoon, 9–7.
