February 20 – On the eve of spring training and Year 3 of the Chicago Cubs' "College of Coaches" era, owner Philip K. Wrigley appoints former American League outfielder and native Chicagoan Bob Kennedy "head coach." But in a departure from the coaching rotations of 1961–1962, it is announced that Kennedy is expected to serve in the post for the full 1963 season. In fact, Kennedy leads the Cubs to an 82–80 mark, their first above-.500 season since 1946, and will hold the head coaching job through June 13, 1965.
March 22 – The New York Mets, who finished last in the National League with a 40–120 record in their inaugural season, purchase pitcher Carl Willey from the Milwaukee Braves. Willey will attempt to boost a pitching rotation that includes Roger Craig, Al Jackson and Tracy Stallard. The Mets will improve to 51–111 in 1963.
April 11 – Warren Spahn of the Milwaukee Braves becomes the all-time winningest left-handed pitcher in Major League Baseball history. His 6–1 victory over the New York Mets gives him 328 career wins, moving him ahead of Eddie Plank as the all-time winningest left-hander. Except for Duke Snider's home run in today's game, no Mets get past second base.
April 13 – After 11 hitless at bats, Cincinnati Reds second baseman Pete Rose records his first major league hit, a triple off Pittsburgh Pirates pitcher Bob Friend. Increased enforcement of the balk rule produces a Major League record seven in the Pirates' 12–4 trouncing of the Reds at Crosley Field. Friend commits four of the balks.
May 19 – Detroit Tigers center fielder Bill Bruton ties a Major League record for most doubles in a single game. Bruton hits his four doubles in consecutive plate appearances, as Detroit defeats the Washington Senators, 5–1. Teammate and rookie pitcher Bill Faul tosses a three-hitter in his first Major League start.
Willie Kirkland of the Cleveland Indians hits a home run in the 11th inning to tie the game 2–2. In the 19th inning, he hits the game-winning home run to defeat the Washington Senators. Kirkland joins Vern Stephens as the only player to hit two extra-inning home runs.
An era ends for the Milwaukee Braves when they trade 36-year-old right-hander Lew Burdette to the St. Louis Cardinals for catcher/outfielder Gene Oliver and young hurler Bob Sadowski. A three-time All-Star, Burdette had formed a formidable one-two pitching tandem with southpaw Warren Spahn since the Braves moved to Wisconsin in 1953, and had carried the team to its 1957 World Series championship with three complete-game victories.
June 18 – Veteran manager Chuck Dressen is called back into harness when he replaces Bob Scheffing as pilot of the struggling Detroit Tigers. For Dressen, 68, the Tigers' job represents his fifth MLB managerial assignment since 1934.
June 21 – Pitcher Early Wynn, 43, in search of his 300th career victory, returns to the Cleveland Indians as a free agent. He had been released by the Chicago White Sox on November 20, 1962.
June 23 – Colorful Jimmy Piersall hits his 100th career home run in a 5–0 New York Mets victory over the Philadelphia Phillies at the Polo Grounds. In celebration, he runs backwards around the bases (although he touches each bag in the correct order); still photos of the stunt make coast-to-coast news but Piersall draws scorn from baseball traditionalists.
June 27 – Outfielder Al Luplow of the Cleveland Indians makes one of the most spectacular catches in Fenway Park history, catching Dick Williams' long drive as he leaps over the right field wall and tumbles into the Boston Red Sox' bullpen. The catch comes in the eighth inning with the tying runs on base, and preserves the Tribe's 6–4 victory over Boston.
July 2 – The Giants' Juan Marichal pitches a 16-inning shutout against the Milwaukee Braves, outdueling Warren Spahn, who hurls 15+1⁄3 scoreless innings before Willie Mays wins the contest 1–0 with a home run in the bottom of the 16th. In the ninth inning, when the Giants' manager suggests Marichal should come out for a pinch hitter, he angrily replies, "I am not going to come out of that game as long as that old man is still pitching." Later, when the Braves' manager suggests to Spahn that it's time he leaves the game, the 42-year-old Spahn replies that if that young kid can still pitch, so can he. When it's over, Marichal has thrown 227 pitches and Spahn 201.
July 9 – At Municipal Stadium, the National League defeats the American League 5–3 in the 1963 Major League Baseball All–Star Game, as the annual Midsummer Classic returns to a single-game format. The Americans out-hit the Nationals 11–6, but MVP Willie Mays puts on a one-man show. Although he's held to a single, Mays collects two runs, two RBI and two stolen bases, and makes a running catch that deprives Joe Pepitone of an extra base hit in the eighth inning. The game marks the 24th and final All-Star appearance of Stan Musial, who pinch hits in the fifth inning. He lines out to right field, leaving behind a .317 batting average (20-for-63) and an All-Star Game record of six home runs.
July 27 – The Los Angeles Angels sign outfielder Jim Piersall the same day he is unconditionally released by the New York Mets. Piersall, 33, will continue his MLB career as a backup outfielder with the Angels until he's released on May 2, 1967.
August 23 – Milwaukee Braves veteran pitcher Warren Spahn sets a National League record for most starts, previously set by Grover Alexander, with his 601st appearance on the mound during a 6–1 win over the Los Angeles Dodgers. Later in 1963, Spahn will match an NL record set by Christy Mathewson with his thirteenth 20-win season, while becoming the oldest pitcher to do so at 42.
August 29 – Helped by a league-record-tying eight home runs, the Minnesota Twins amass a team-record forty-seven total bases in the first game of a double-header at D.C. Stadium. Harmon Killebrew and Vic Power both strike for two homers in the 14–2 victory. In the second game, a 10–1 Minnesota win, the Twins hit four more homers for a team-record even dozen on the day.
September 10 – The Alous become the first brother trio to bat consecutively in one game, during the eighth inning of a San Francisco Giants' 4–2 loss to the New York Mets at the Polo Grounds. Jesús pinch-hits in his Major League debut and grounds out to shortstop Al Moran; Matty, also pinch-hitting, strikes out, and Felipe ends the inning by grounding out to pitcher Carl Willey, who goes the distance for the victory.
September 13:
Cleveland Indians pitcher Early Wynn finally wins his 300th and final game thanks to a little help from his bullpen. After losing eight straight starts and struggling through five innings against the Kansas City Athletics, Wynn is replaced by relief man Jerry Walker, who tosses four scoreless innings to save Wynn's 7–4 triumph.
Playing in his first MLB game, Los Angeles Dodgers first baseman Dick Nen clubs a ninth-inning, game-tying home run over the roof at Busch Stadium off Ron Taylor of the St. Louis Cardinals. The Dodgers go on to win in the 13th, 6–5, completing a three-game road sweep of the Redbirds and effectively wrecking St. Louis' pennant drive. When the season ends September 29, Los Angeles' ultimate winning margin is six games.
In the final regular-season game ever played at the Polo Grounds, the Philadelphia Phillies defeat the New York Mets 6–1. New York gets its only run on Jim Hickman's fourth-inning home run, the last home run to be hit at the park.
Outfielder Jimmie Hall of the Minnesota Twins hits his 33rd and final home run of the year. No other rookie without previous-year at bats has hit more. Hall tops the current record-holder, Boston's Ted Williams, who hit 31 in 1939.
September 27 – Manager Harry Craft of the Houston Colt .45s fields the "Baby Colts", a starting lineup with an average age of nineteen years, against the New York Mets at Colt Stadium. The oldest player used by Houston all game is 26-year-old Dick Drott, who pitched the ninth inning.[2]
John Paciorek makes his MLB debut for the Houston Colt .45s at age 18, lashing three hits, driving in four runs, and drawing two walks. He reaches base in all five plate appearances for a batting average of 1.000 and an OPS of 2.000. However, this will be Paciorek's only appearance in a major league game, after he suffers an injury in the minors that ends his career by the time he's 24.
October 6 – At Dodger Stadium, Sandy Koufax defeats the New York Yankees, 2–1, completing a shocking World Series sweep for the Los Angeles Dodgers. Whitey Ford gives up only two hits, both by Frank Howard, who belts a long home run in the fifth inning to start the Dodgers' scoring. In the Series, the Yankees bat just .171 and score only four runs, the second-lowest total in World Series history. Curiously, the Dodgers would set the mark for the fewest runs scored in a World Series only three years later, falling victim to a decisive sweep at the hands of the Baltimore Orioles.
October 14 – The Cleveland Indians release 300-game-winner and future Hall-of-Famer Early Wynn and name him their new pitching coach.
October 29 – The New York Yankees release catcher and playing coach Yogi Berra so he can manage the 1964 Bombers. He succeeds Ralph Houk, who moves up to general manager, replacing the retiring Roy Hamey.
November 19 – United States Marine Corps veteran and former New York Yankees outfielder Hank Bauer signs a one-year contract to manage the Baltimore Orioles. Bauer succeeds Billy Hitchcock, fired September 29, and is expected to bring greater discipline to the Orioles' culture. Bauer's term will last into July 1968, during which the Birds narrowly miss the 1964 pennant, but take home the 66-year-old franchise's first-ever World Series championship in 1966.
November 26 – Second baseman Pete Rose is a landslide winner of National League Rookie of the Year honors, taking 17 of 20 first place votes, with the others going to Ron Hunt (2) and Ray Culp (1). Rose becomes the second Cincinnati Reds player to win the award, joining Frank Robinson.
November 27:
Chicago White Sox pitcher Gary Peters, who posted a 19–8 record with 189 strikeouts and a 2.33 ERA, edges teammate third baseman Pete Ward (.295 BA, 22 HR, 84 RBI) and Minnesota Twins outfielder Jimmie Hall (.260, 33, 80) for American League Rookie of the Year honors. Peters takes 10 of 20 first-place votes, Ward six and Hall four.
