Events

January

• January 4 – The New York Highlanders of the American League announce plans to play on Sundays at Ridgewood Park in Queens, NY, but the National League Brooklyn Superbas object the proposal. By the time Sunday's games are legal only in the cities of Detroit, St. Louis, Chicago and Cincinnati.^{[citation needed]}

February

• February 29 – Pepper Martin is born in Temple, Oklahoma. Amazingly, with more than 19,000 different Major League Baseball players in the sport's history, between 1836 and 2018, only 11 have been born on a Leap Day.^[1][2] Dubbed as the Wild Horse of the Osage because of his daring and aggressive baserunning abilities,^[3] Martin played as a third baseman and an outfielder for the St. Louis Cardinals in a span of 13 seasons between 1928 and 1944, earning two World Series titles, four All-Star Game selections and four National League stolen bases titles. But Martin is probably best known for his heroics in the 1931 World Series, when he led the Cardinals in average (.500), hits (12), doubles (4), runs (5), RBI (5), stolen bases (5) and added one home run in the seven-game triumph over the highly favored Philadelphia Athletics, making also a running catch to cut a ninth-inning rally by the Athletics in the decisive Game 7.^[3]

March

• March 16 – Buddy Myer is born in Ellisville, Mississippi.^[4] A two-time All-Star and American League champion bat, Myer was the second baseman of the Washington Senators club when they won their last AL pennant in 1933.^[4] He posted a .330/.389/.406 slash line with 2,131 hits in 1,923 games. Notably, Myer walked more than twice as many times as he struck out (965-to-428) during 17 seasons from 1925 through 1941, including a stint with the Boston Red Sox in 1927 and 1928.^[4] Myer was often cited as one of the few Jewish baseball stars and was chosen for the International Jewish Sports Hall of Fame, but he was a member of the Baptist church.^[5]

April

May

• May 5 – Cy Young pitches a perfect game, as the Boston Americans defeat the Philadelphia Athletics, 3–0, at Huntington Avenue Grounds.^[6] This is considered the List of Major League Baseball perfect games#Modern era first perfect game in the modern era.
• May 11 – Following his perfect game against the Philadelphia Athletics six days before, Cy Young of the Boston Americans pitched another six hitless innings against the Detroit Tigers, until Sam Crawford stroked a single to end the string. Before his perfection start, Young had already pitched eighth consecutive innings without allowing a base hit. On April 25, he pitched two innings at Philadelphia, then he hurled six innings in relief against the Washington Senators. As a result, the record books credited Young with 23 consecutive hitless innings based on these four games, which is considered a record in Major League Baseball history. No one has ever equaled that mark.^[7]
• May 21 – Boston Americans shortstop Bill O'Neill made history when he committed six errors in a 13-inning, 5–3 loss to the St. Louis Browns at Huntington Avenue Grounds, to set a 20th-century single-game record.^[8]
• May 27 – New York Giants first baseman Dan McGann set a Major League Baseball record with five stolen bases in a single-game, a feat not matched until Davey Lopes did it for the Los Angeles Dodgers in 1974, and not surpassed until Atlanta Braves' Otis Nixon stole six bases in 1991.^[9]

June

• June 11 – Chicago Cubs pitcher Bob Wicker pitches nine innings without allowing a hit. He surrenders a hit in the 10th inning, but it would be the only hit he allows in the game. The Cubs would go on the beat the New York Giants, 1–0, in 12 innings.
• June 20 - Duff Cooley of the Boston Beaneaters hits for the cycle in the second game of a doubleheader against the Philadelphia Phillies in a 9-0 Boston victory.
• June 23 – Kip Selbach of the Washington Senators ties a record by committing 3 errors from the outfield in one inning.

July

• July 16 – New York Highlanders right-handed starter Jack Chesbro steals home plate in the bottom of the 10th inning, scoring a walk-off run while winning his own game against the Detroit Tigers, 9-8, at Hilltop Park. Chesbro, who entered the game in relief duties, led off the inning with a single, moved to third base on a pair of outs, then achieved this rare feat. Chesbro, a notorious spitballer, set a Major League pitching record with 41 wins in 1904.^[10]

August

• August 17 – Boston Americans pitcher Jesse Tannehill tosses a no-hitter against the Chicago White Sox in a 6–0 win at South Side Park.^[6]
• August 24 – New York Highlanders left fielder Willie Keeler collects two home runs against the visiting St. Louis Browns in a 9–1 win at Hilltop Park. Both drives are inside-the-park.^[11]

September

• September 1 - The New York Giants selected Moonlight Graham in the Rule five draft. This is the same Moonlight Graham that is fictionalized in the movie Field Of Dreams.
• September 5 – At the Polo Grounds, the New York Giants swept a doubleheader from the Boston Beaneaters in front of 37,000 fans. Christy Mathewson won a pitching duel with Kaiser Wilhelm in the opener, 1–0, when Jim Delahanty scored on a triple by Tom Needham in the bottom of the ninth inning. The second game of the Labor Day twin-bill was won on a Sam Mertes single in the bottom of the ninth that brought Red Ames with the winning run. The climax to the successful day inspired a group of fans to carry Giants manager John McGraw off the field on their shoulders; McGraw was dropped during the excitement and suffered a sprained ankle.^{[citation needed]}

October

• October 3 – Christy Mathewson of the New York Giants strikes out 16 in a 3–1 victory over the St. Louis Cardinals at Polo Grounds. His 16 strikeouts set a new record in the major leagues as he finishes the game in one hour and 15 minutes.^[12]
• October 4 – New York Giants outfielder Sam Mertes hits for the cycle in a 7–3 loss to the St. Louis Cardinals at Polo Grounds.^[12]
• October 7 – George Stovall hit a home run off his brother Jesse Stovall. That particular feat was a Major League first and an event that remained unduplicated until Rick Ferrell hit a homer off Wes Ferrell in 1933 then Joe Niekro went deep against Phil Niekro in 1976.^[11]
• October 8 – Jack Chesbro earned his 41st victory of the season as the New York Highlanders defeated the Boston Americans, 3–2. The 41 wins by a pitcher in a season are a modern record in Major League history. Previously, the future Hall of Famer won his 14th consecutive game on August 10 (a record at the time), pitched 30 consecutive complete games at a time, and would complete 48 of his 51 starts of the season.^[13]
• October 10 – The regular season ends with a doubleheader at Hilltop Park in New York City. The Boston Americans clinched the American League pennant in the opener with a 3–2 victory over the New York Highlanders, while New York won the second game, 1–0, in 10 innings.^[6] It would also be the last time for a full century that the Boston AL team, who would later formally become the Boston Red Sox in 1908, would beat the New York AL team in a pennant-deciding game.

Postseason

• The World Series was cancelled due to a business rivalry between the two leagues. During spring training, New York Giants owner John T. Brush said that there will never be a series between two clubs based in the same city, in response to a preseason offer from New York Highlanders co-owner Frank J. Farrell.^[14] Nevertheless, the Boston Americans pennant victory over the Highlanders had historical significance in several ways. Although Boston had won instead, Brush and team's manager John McGraw refused to face the Americans in what would've been the second World Series.^[15] Brush announced "There is nothing in the constitution or playing rules of the National League which requires its victorious club to submit its championship honors to a contest with a victorious club in a minor league," according to his biography at SABR.^[16] The resulting backlash by the press caused Brush to take a stance and lead the committee to formalize the rules governing the future World Series.^[16] This would be the last time for 90 years that a World Series was not played, when it was canceled on September 14 of 1994 due to an MLB Players Association strike. It would also be the last time for 100 years that the Boston AL team, who would later formally become the Boston Red Sox in 1908, would beat the New York AL team in a pennant-deciding game until the 2004 American League Championship Series.
