May 1 - The Houston Astros, no-hit the day before by Jim Maloney of the Cincinnati Reds, answer back as Don Wilson pitches a 4-0 no-hitter, with 13 strikeouts over the Reds. Houston ties a National League record with just one assist. In Wilson's previous start against Cincinnati, on April 22, he gave up six runs in five innings in a 14-0 loss. The back-to-back no-hitters are only the second in Major League history, the feat having been accomplished just the year before by Gaylord Perry and Ray Washburn.
June 22 - The Cubs score four runs in the ninth inning to defeat the Montreal Expos 7-6 in the first game of a double-header at Wrigley Field. Jim Hickman hit a 2-run walk-off homer.
June 26 - Jim Hickman's home run in the 10th inning defeats the Pittsburgh Pirates 7-5 at Wrigley Field. On the spur of the moment Ron Santo leaped in the air and clicked his heels 3 times on the way to the clubhouse. The victory dance became a hit with euphoric Cub fans.
July 8 - With three runs in the 9th inning, the New York Mets beat the Chicago Cubs 4-3, cutting Chicago's lead in the National League East to four games. Chicago's Ron Santo rips into center fielder Don Young for two misplays in the outfield; Santo apologizes the next day for criticizing Young, who had left early and didn't take the team bus. Santo is later booed in his first game back at Wrigley Field.
July 30 - After losing the first game of a doubleheader with the Houston Astros 16-3, the New York Mets were down 7-0 in the third inning when Johnny Edwards hit a double to Cleon Jones in left field to make the score 8-0. Mets manager Gil Hodges emerged from the dugout, walked past Nolan Ryan on the mound, and walked all the way out to left field. A few minutes later, Hodges walked back to the dugout, with Jones a few paces behind him, and replaced Jones in left with Ron Swoboda. According to Jones, he pointed down to the water filled turf. Hodges then said that something must be wrong with Jones's ankle and pulled him for that reason (Jones was kept out of the line-up for the next two games, and used only as a pinch hitter in the two after that). Newspapers report that Jones was removed for failure to hustle, and Hodges decided to do so publicly to show that he would not tolerate lack of effort on his team, even from its star player.
August 5 - The Pittsburgh Pirates' Willie Stargell hits the first home run ever hit completely out of Dodger Stadium. Los Angeles pitcher Alan Foster surrenders the 506-foot blast—to date, the longest home run in Dodger Stadium history. (Stargell will hit another homer out of Dodger Stadium, off Andy Messersmith in 1973.) The mammoth home run comes in the seventh inning and breaks a 3-3 tie, a three-run home run by Andy Kosco having tied the game for the Dodgers in the bottom of the sixth; Pittsburgh scores seven more runs in the ninth inning and defeats Los Angeles 11-3.
Citing damage to his right shoulder, Don Drysdale retires from the Los Angeles Dodgers. He is the last player still playing for the Dodgers that had also played in Brooklyn.
August 14 - In the National League Eastern Division, the Chicago Cubs lead the St. Louis Cardinals by 8.5 games and the New York Mets by 9.5 games.
August 19 - At Wrigley Field, Ken Holtzman of the Chicago Cubsno-hits the Atlanta Braves 3-0 without striking out a single batter the entire game. Only one other pitcher in Major League history, Sad Sam Jones in 1923, has hurled a no-hitter without the benefit of a strikeout. Holtzman survives a scare in the seventh as Hank Aaron's fly ball to deep left field leading off the inning appears to be going over the wall for a home run; however, a stiff wind cuts into the ball and enables Billy Williams to catch it at the warning track. Aaron will ground out to Cubs' second baseman Glenn Beckert for the game's final out.
September 9 - During the Mets' 7-1 victory over the Chicago Cubs at Shea, a black cat jumps on the field and runs past Ron Santo in the on-deck circle.
