The following are the baseball events of the year 1962 throughout the world. The 1962 season is perhaps most notable for the dismal 40–120 record of the New York Mets, the third-worst winning percentage and the record for most games lost since 1900.
April 12 – In his Major League debut, Pete Richert of the Los Angeles Dodgers ties Karl Spooner's record by striking out the first six Major League batters he faces. He enters the game against the Cincinnati Reds at Dodger Stadium with two out in the second inning and strikes out Vada Pinson for the final out. He then records a four-strikeout third inning; the victims are Frank Robinson, Gordy Coleman (who reaches first on a Johnny Roseboro passed ball), Wally Post and Johnny Edwards. To date, Richert is the only pitcher to strike out four batters in one inning in his Major League debut. His record-tying sixth strikeout is of Tommy Harper leading off the fourth inning. The Dodgers defeat the Reds 11–7 with Richert gaining the victory, having struck out seven batters, walking none, and allowing no hits in 31⁄3 innings.
May 12 – New York Mets relief pitcher Craig Anderson wins both ends of a doubleheader against the Milwaukee Braves. Success will soon turn to failure, because Anderson will lose his next 16 decisions on the season and 19 decisions overall. In fact, he will never win another game in the major leagues.
May 29 – Ernie Banks hits three home runs, but his Chicago Cubs still fall to the Milwaukee Braves 11–9 at Wrigley Field in Chicago.
June 18 – At the Polo Grounds, Hank Aaron of the Milwaukee Braves hits a home run over the center field wall. The shot, a grand slam, comes off Jay Hook in the Braves' 7-1 victory over the New York Mets and is the second in back-to-back days, and the third overall, to clear that wall. The day before, Lou Brock of the Chicago Cubs had hit one over the center field wall, off the Mets' Al Jackson in the first game of a doubleheader. Joe Adcock had been the only other player to hit a home run over the Polo Grounds' center field wall, doing so for the Braves against the New York Giants on April 29, 1953.
June 27 – In Pittsburgh, the Mets' Richie Ashburn singles in the fourth inning against Bob Friend. It is Ashburn's 2,500th career hit, and he is the 39th player in history to reach that level. the Pirates win the game, 6-5, in 10 innings.
June 30 – At Dodger Stadium, Sandy Koufax of the Los Angeles Dodgers no-hits the New York Mets 5–0. He begins the game by striking out the first three batters (Richie Ashburn, Rod Kanehl and Félix Mantilla) on nine pitches. The no-hitter is the first by a Dodger since the franchise's move from Brooklyn after the 1957 season, as well as the only one to feature a nine-pitch, three strikeout half-inning to date. Koufax will go on to pitch no-hitters in each of the next three seasons, including a perfect game in 1965; his record of four career no-hitters will be broken by Nolan Ryan in 1981.
July 9 – At a meeting held in conjunction with the All-Star Game, the major league players request a reduced schedule for the 1963 season. They also vote unanimously to continue playing two All-Star Games each year.
July 14 – Unfortunately for Ralph Branca, it is 11 years too late and it doesn't count anyway. In the New York Mets' first Old-Timers' Game, reliever Ralph Branca faces Bobby Thomson, the man who hit the historic 1951 home run against him to give the Giants the 1951 pennant. This time Branca gets Thomson out on a fly ball to center field. In the real game itself, the Dodgers smash the Mets, 17-0.
July 20 – The Cardinals' Minnie Miñoso returns to action for the first time since May 11, when he fractured his skull and broke his right wrist running into an outfield wall. On August 19, he is hit by a pitch by the Mets' Craig Anderson in the 6th and suffers a broken bone in his left forearm.
July 22 – The Chicago White Sox Floyd Robinson is 6 for 6 – all singles – in a 7-3 victory over the Boston Red Sox.
July 26 – Warren Spahn of the Milwaukee Braves sets the National League record for home runs by a pitcher, when he hits his 31st off New York's Craig Anderson. Spahn also deals the Mets their 11th straight loss in a 6–1 Milwaukee victory.
November 23 – Los Angeles Dodgers shortstop Maury Wills, whose 104 stolen bases broke a major league season-record set by Ty Cobb, wins the National League Most Valuable Player Award. In a controversial vote, Wills beats out teammate Tommy Davis, who led the league with a .346 batting average and 153 RBI.
After 61 years, the American Association (AAA) folds, with some of the franchises being absorbed by the International League and the Pacific Coast League. The PCL adds the Dallas-Fort Worth, Texas; Denver, Colorado and Oklahoma City, Oklahoma clubs and drops the Vancouver, BC club. The International League adds the Indianapolis, Indiana and Little Rock, Arkansas clubs. As a result, both leagues became ten-club leagues.
MLB officials and player representatives agree to return to a single All-Star Game in 1963. The players' pension fund will receive 95 percent of the one game's proceeds (rather than 60 percent of the two games).
