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.

April 13: After 11 hitless at bats, Cincinnati second baseman Pete Rose records his first major league hit, a triple off Pittsburgh'sBob Friend.

July 9 - At Municipal Stadium, the National League wins 5–3 over the American League in the All-Star Game. After four years, MLB had decided to return to the original single-game format. The American League out-hit the National League 11-6, but the effort went in vain as MVP Willie Mays put on a one-man show. Although he was held to a single, Mays collected two runs, two RBI, two stolen bases and made the defensive play of the game — a running catch that deprived Joe Pepitone of an extra base in the eighth inning. This game also marked the 24th and final All-Star appearance of Stan Musial, who pinch-hit in the fifth inning. He lined out to right field, leaving behind a .317 batting average (20-for-63) and an All-Star Game record of six home runs.
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 enough, the Dodgers would set the mark for the least runs scored in a World Series only three years later, falling victim to a decisive sweep at the hands of the Baltimore Orioles.
