January 29 – Billy Hamilton and Max Carey are voted into the Hall of Fame by the Veterans Committee.
April 11 – At New York's Yankee Stadium, the Minnesota Twins, in their first game since their move from Washington, shut out the Yankees 6–0. The Twins' Pedro Ramos was the winning pitcher. Ramos had a 2-run single and allowed just 3 singles in beating the Yankee starting pitcher, Whitey Ford.
April 22 – The Boston Red Sox snap a 13-game losing streak in Chicago's Comiskey Park by edging the Chicago White Sox 7–6 on Pumpsie Green's 11th-inning home run.
April 27 – The Los Angeles Angels draw a disappointing crowd of 11,931 for their first-ever home opener against the Minnesota Twins at Los Angeles' Wrigley Field. Ty Cobb, in his last appearance at a ball park, throws out the first ball. The Twins' Camilo Pascual spoils the opener by winning, 4–2, sending the Angels to their eighth loss in nine games.
April 30 – San Francisco Giants slugger Willie Mays became the ninth player to hit four home runs in a single game as the Giants beat the Milwaukee Braves 14–4 at Milwaukee's County Stadium.
May 31 – Boston Red Sox outfielder Carroll Hardy pinch-hits for rookie Carl Yastrzemski. On September 20, 1960, Hardy pinch hit for Ted Williams, making him the only player to go in for both future Hall of Famers. Hardy also hit his first major league home run pinch-hitting for Roger Maris when both were at Cleveland (May 18, 1958).
June 8 – In the course of a 10–8 loss to the Cincinnati Reds, the Milwaukee Braves become the first team to hit 4 home runs in consecutive at bats.

July 4 – Willie Mays hits 300th career home run.
July 11 – Strong winds at Candlestick Park dominate the first All-Star Game of the season. A capacity crowd sees Giants pitcher Stu Miller blown off the mound in the ninth inning when a balk is called, and it enables the American League to forge a 3–3 tie before losing 5–4 in 10 innings.
July 17 – Commissioner Ford Frick decrees that Babe Ruth's record of 60 home runs in a 154-game schedule in 1927 "cannot be broken unless some batter hits 61 or more within his club's first 154 games." Two days later, Frick, an old friend of Ruth, announces that should Ruth's record be beaten after 154 games, the record will carry an asterisk. When asked about the ruling, Roger Maris replies, "A season is a season." This is also the day that one of baseball's greatest hitters passes away, Ty Cobb, aged 74.
July 31 – At Fenway Park, the second All-Star Game of the year ends in a 1–1 tie as heavy rain halted play. It is the first of two ties in All-Star history. The other would occur in 2002.
August 11 – Warren Spahn of the Milwaukee Braves records his 300th career win.
August 20 – The Philadelphia Phillies snap a modern-day record 23-game losing streak, defeating the Milwaukee Braves 7–4 in the second game of a doubleheader at Milwaukee County Stadium. Phillie pitcher John Buzhardt goes the distance for the victory; he had also been the winning pitcher in the Phillies' last victory prior to the start of the losing streak, on July 28 against the San Francisco Giants.
August 22 – Roger Maris becomes the first player to hit his 50th home run of the season in the month of August as the Yankees lose to the Los Angeles Angels, 4–3. Angels pitcher Ken McBride tees up the gopher ball in the sixth inning with one on.

September 2 – Milwaukee Braves manager Chuck Dressen (71–58) is fired and executive vice president Birdie Tebbetts becomes the new Braves manager.
September 20 – Helped by home runs by Yogi Berra and Roger Maris, the New York Yankees defeat the Baltimore Orioles 4–2, clinching their second straight American League pennant and 11th in 13 years. The Yankees would finish with a 109–53 record, tying the 1969 Orioles for the best won-loss record of the decade.
The Cincinnati Reds clinch their first National League pennant since 1940. Homers by Frank Robinson and pinch hitter Jerry Lynch (a tie breaker in the eighth inning) give the Reds an 8–3 win over the Chicago Cubs at Wrigley Field.
Roger Maris hits his major league record-tying 60th home run of the season, a third-inning solo shot against Jack Fisher of the Baltimore Orioles.
October 1 – Before a small crowd at Yankee Stadium, Roger Maris smacks a 2–0 pitch from Boston's Tracy Stallard into the right field stands for his 61st home run of the season, setting a new major league record for home runs in a season. The record will stand until Mark McGwire of the St. Louis Cardinals breaks it in 1998.
October 9 – In Game 5 of the World Series, Johnny Blanchard and Héctor López spark a five-run first inning and 13–5 win for the New York Yankees over the Cincinnati Reds. Blanchard and López hit home runs, and López drives in five runs. Bud Daley's long relief effort wraps up the Series, as Ralph Houk becomes the third rookie manager to guide a World Series winner. Whitey Ford is named the Series MVP.
1961 Major League Baseball season Wikipedia
The 1961 Major League Baseball season saw the New York Yankees defeat the Cincinnati Reds in five games in the World Series. The season is best known for Yankee teammates Roger Maris’ and Mickey Mantle's pursuit of Babe Ruth's prestigious 34-year-old single-season home run record of 60. Maris ultimately broke the record when he hit his 61st home run on the final day of the regular season, while Mantle was forced out of the lineup in late-September due to a hip infection and finished with 54 home runs.
In response to the proposed Continental League, the American League expanded by two teams in the first MLB expansion since 1901. The original Washington Senators moved to Minnesota and became the Minnesota Twins. The American League therefore placed a new team in Washington, also called the Senators. Also, the American League placed a team in Los Angeles called the Los Angeles Angels.
In order to keep its schedule balanced, the American League season was extended by eight games. Previously, teams had played 154 games (22 games per opponent), but from 1961 AL teams would play opponents 18 times each for a total of 162 games. The National League played a 154 game schedule for the final time in 1961 before switching to 162 games when they also expanded to ten teams for the following season.
