April 14 - In his Major League debut, Billy Rohr of the Boston Red Sox has a no-hitter broken up with two out in the ninth inning—and one strike to go—of a 3-0 victory over the New York Yankees and Whitey Ford at Yankee Stadium. A single by Elston Howard breaks up the bid; this will be the only hit Rohr will allow. Exactly one week later, Rohr again defeats the Yankees in a complete game victory, this time at Fenway Park—the second of: 1) the only two games Rohr will win this season and 2) the only three he will win as a Major Leaguer.
July 2 - The Chicago Cubs moved into a tie for first place with the St. Louis Cardinals after defeating the Cincinnati Reds 4-1 before 40,464 at Wrigley Field.

It was the first time the Cubs were in first place since the 1945 season.
July 4 - The Niekro brothers face each other for the first time, with Phil Niekro pitching for the Atlanta Braves and Joe Niekro hurling for the Chicago Cubs. Phil beat Joe in an 8-3 decision in the first game of a double-header in Atlanta. The Braves also won the second game 4-2.

September 10 - In a clutch performance between two of the four teams in the American League pennant race, Joe Horlen of the Chicago White Soxno-hits the Detroit Tigers 6-0, in the first game of a doubleheader at Comiskey Park. The White Sox also shut out the Tigers in the nightcap, with Cisco Carlos gaining his first Major League victory, and pull into a third-place tie with the Tigers and within 11⁄2 games of the first-place Minnesota Twins.
September 27 - In the tight AL pennant race, the possibility of a four-way tie is eliminated as the Twins and Red Sox both lose (5-1 to California and 6-0 to Cleveland, respectively). Minnesota now has a 91-69 won-lost record and Boston is 90-70, and the only games left for those two teams are two games against each other.
September 29 - The White Sox lose 1-0 to the Washington Senators and are eliminated from the AL pennant race. Chicago is now 89-71, and can win a maximum of 91 games, and must finish behind the Twins or the Red Sox (those two teams only have the two games against each other left to play). The only remaining tie possibilities are Twins-Tigers or Red Sox-Tigers.

One of the closest American League pennant races ever enters the season's final day with the Red Sox and Twins tied for first place and the Tigers one-half game back. The Red Sox and Twins play a game against each other, with the winner clinching a tie for the pennant and the loser being eliminated. In that game, eventual American League MVPCarl Yastrzemski goes 4 for 4 as the Red Sox beat the Twins 5-3. The Tigers can tie the Red Sox if they sweep a doubleheader from the California Angels in Detroit. The Tigers win the first game 6-4, but their bullpen fails in the finale and the Angels win 8-5 to give the Red Sox the pennant with no playoff.
Today's doubleheader is the second in as many days for the Tigers and the Angels. The doubleheaders are the result of earlier postponements of games which are needed in the deciding of the pennant race. Many years later, also in the AL, there will be a case of a day doubleheader scheduled on the day after a twi-night doubleheader; there will be a player protest to AL president Bobby Brown, who will rule that there will be only one game on the second day.
For the first time since 1937 both Chicago teams succeed in winning at least 85 games during the regular season. For the Cubs it was only their 2nd winning season (1963 being the other one) since 1946.
