• January 16 – Curt Flood, Gold Glove outfielder of the St. Louis Cardinals, files a civil lawsuit challenging Major League Baseball's reserve clause, a suit that will have historic implications. Flood refused to report to the Philadelphia Phillies after he was traded by the Cardinals three months ago, contending the baseball rule violates federal antitrust laws.
• January 17 – The Sporting News names Willie Mays as Player of the Decade for the 1960s.
• January 20 – Lou Boudreau is elected to the Hall of Fame by the Baseball Writers' Association of America on 232 of 300 ballots. Ralph Kiner finishes second with 167, 58 votes short.

• February 19 – Commissioner Bowie Kuhn announces the suspension of Detroit Tigers pitcher Denny McLain, effective April 1, for McLain's alleged involvement in a bookmaking operation. The suspension is indefinite, but will later be set at three months.

• April 1 – The Milwaukee Brewers organization, headed by Bud Selig, purchases the Seattle Pilots franchise for $10,800,000. Although negotiations were conducted over a period of months, it was not until March 31 when a federal bankruptcy judge declared the Pilots bankrupt. Brewers tickets go on sale the next day. Team equipment is shipped to Milwaukee County Stadium, where the Pilots insignia is ripped off of the uniforms, since there is no time for new uniforms to be made.
• April 7 :
  • Major league baseball returns to Wisconsin after a 4-year absence as the Brewers play their first game in Milwaukee, losing to the California Angels 12–0 before a crowd of 37,237.
  • Pitcher Dave McNally strikes out 13 in nine innings as the Baltimore Orioles rip the Indians, 8-2, in Opening Day at Cleveland Stadium. The attack is led by Paul Blair, who drives in a pair of runs and scores three times. McNally holds the Indians to two runs on four hits and three walks to get the win. Rookie Roy Foster belts a two-run home run for the only offense for Cleveland.
  • In Minnesota, left-fielder Brant Alyea leads the Twins over the Chicago White Sox, 12-0. His 4-for-4 day includes two homers and seven RBI, the latter setting a major league Opening Day record.
• April 11 – At Comiskey Park, Danny Walton hits the first two home runs in Milwaukee Brewers history, both two-run shots coming against White Sox starter Billy Wynne. The Brewers win for the first time, 8-4.
• April 18 - Nolan Ryan gave up only one hit in the first inning as he set a then New York Mets record by striking up 15 batters in a 7-0 Mets victory over the Philadelphia Phillies at Shea Stadium.
• April 22 – The New York Mets' Tom Seaver strikes out 19 San Diego Padres, including the last 10 in succession, in winning 2-1 for the Mets. Mike Corkins takes the loss. In this century, no one had ever struck out 10 in a row, a major league record. Counting the 10 whiffs, the Pads have struck out 29 times in two games, a National League record that will be topped in 1998 when the Houston Astros miss 31 times in two days. Jerry Grote adds one foul fly catch to his 19 putouts via K's.

• May 10 – Hoyt Wilhelm makes his 1,000th pitching appearance; the first pitcher in history to do so.
• May 12 – At Chicago's Wrigley Field, Ernie Banks becomes the 8th member of the 500 home run club, connecting off Atlanta Braves pitcher Pat Jarvis during a 4–3, 11-inning Chicago Cubs win over the Braves. It his also his 1,600th career run batted in. Ex-Cub Frank Secory is umpiring this game, as he was one of the umpires in the 1953 game in which Banks hit his first career home run. Banks' teammate Billy Williams also homer in the 9th inning to tie the game, while Ron Santo's RBI single in the 11th wins it. Atlanta's Rico Carty, meanwhile, has three singles and has hit in 30 consecutive games.
• May 17 – In the second game of a double header, Hank Aaron of the Atlanta Braves collected his 3,000 career hit with an infield single as well as his 517th home run off of pitcher Wayne Granger, during a 7–6, 15-inning loss to the Cincinnati Reds, becoming the founding member of the 3000-500 Club. Through the years, Willie Mays, Eddie Murray, Rafael Palmeiro, Albert Pujols and Alex Rodriguez would join the select club.

• June 5 – Bert Blyleven makes his major league debut with the Minnesota Twins, and gives up a lead-off home run to Washington Senators outfielder Lee Maye. Blyleven holds on for a 2–1 victory, the first of a 287 wins career that will propel his induction into the Baseball Hall of Fame and Museum.
• June 12 – In the first game of a double header at San Diego Stadium, Dock Ellis of the Pittsburgh Pirates no-hits the San Diego Padres 2–0. Years later, Ellis would claim that he was under the influence of LSD during the entire game.
• June 8 – Both Major League Baseball players and management agreed to end their labor dispute by settling on a new standard contract. Among the compromises that benefited the players was a raise in the minimum league salary from $10,000 to $12,000 per season.
• June 17 – At Candlestick Park, Ernie Banks and Willie Mays become the first members of the 500 home run club to each hit a home run in the same game. In the eighth inning of the Chicago Cubs' game against the San Francisco Giants, Banks hits his 504th career home run, a three-run shot off Giant reliever Mike Davison. Mays then hits his 615th career home run off the Cubs' Ken Holtzman in the bottom half of the same inning. The Cubs defeat the Giants, 6-1.
• June 21 – The Detroit Tigers' César Gutiérrez gets seven hits in seven at bats in 12 innings against the Cleveland Indians, setting an American League mark and tying a major league record for most hits in one game.[1]

  • The Cincinnati Reds defeat the San Francisco Giants, 5-4 in the final game that the Reds will play at Crosley Field.
• June 26 – Frank Robinson of the Baltimore Orioles hits grand slams in consecutive innings, the fourth and fifth, in a 12-2 victory over the Washington Senators at Robert F. Kennedy Stadium. The same runners are on base both times: Dave McNally on third, Don Buford on second and Paul Blair on first.
• June 28 – The Pittsburgh Pirates defeat the Chicago Cubs in both games of a doubleheader, 3-2 and 4-1, in the last two games played at Forbes Field.
• June 30 – Riverfront Stadium opens with the Cincinnati Reds losing to the Atlanta Braves, 8-2.

• July 2 :
  • Against the New York Yankees at Tiger Stadium, Joe Niekro of the Detroit Tigers has a no-hitter broken up with one out in the ninth on a Horace Clarke single, the only hit Niekro will allow in a 5-0 Tiger victory. This is the third no-hit bid Clarke has broken up in the ninth inning in less than a month; he had foiled bids by Jim Rooker on June 4 and by Sonny Siebert (who had already pitched a no-hitter in 1966) on June 19.
  • John Bateman of the Montreal Expos set a team record with seven runs batted in to pace the Expos to a 13–10 victory over the St. Louis Cardinals. Bateman started his feat with a grand slam in the Expos' six-run first inning.
• July 3 – Clyde Wright of the California Angels has a doubly memorable day. In a ceremony before the Angels' game against the Oakland Athletics at Anaheim Stadium, the former star pitcher at Carson-Newman College (with whom he won an NAIA Baseball World Series title in 1965) is inducted into the NAIA Hall of Fame. He then no-hits the Athletics 4-0, the first no-hitter in the stadium's history.
• July 8 – San Francisco Giants third baseman Jim Ray Hart tied a modern Major League record with six runs batted in during one inning with all coming in the fifth. As a result, Hart slammed a three-run home run and three-run triple in the frame, and eventually completed his feat by hitting for the cycle en route to a 13–0 victory over the Atlanta Braves.
• July 14 – At Riverfront Stadium, the National League wins its eighth straight All-Star Game, a 12-inning 5–4 victory. Pete Rose crashes into Cleveland Indians catcher Ray Fosse to score the winning run on Jim Hickman's single. Fosse, who never had the ball, hurts his right shoulder and is taken to the hospital. The game is scoreless until the 6th inning, with the NL limited to three hits in the first eight innings. In the 9th, the NL tees off on Catfish Hunter, driving in three runs to tie. Dick Dietz hits a leadoff home run in the inning. Claude Osteen pitches the 10th for the win, and Carl Yastrzemski of the Boston Red Sox captures the MVP trophy for the American League. This All-Star Game voting was finally returned to the fans as punch-card ballots debuted in major league ballparks across the nation, being the first time since 1958 that the exhibition's squads were not entirely selected by managers, coaches and players.
• July 16 – Pittsburgh's Three Rivers Stadium was opened to the public, but the Cincinnati Reds spoiled the party as they beat the Pittsburgh Pirates, 4–3, before a crowd of 48,846. The first hit at Three Rivers Stadium was a single by Pittsburgh's Richie Hebner. The first home run at the new ballpark was hit by Cincinnati's Tony Pérez.
• July 18 – Willie Mays of the San Francisco Giants records his 3,000th career hit.
• July 20 – At Dodger Stadium, Bill Singer of the Los Angeles Dodgers no-hits the Philadelphia Phillies, 5–0. Singer's catcher, Jeff Torborg, had caught Sandy Koufax's perfect game in 1965, and will later catch the first of Nolan Ryan's seven no-hitters, in 1973.
• July 26 – Johnny Bench of the Cincinnati Reds hit three straight home runs off St. Louis Cardinals pitcher Steve Carlton. On the same day, Orlando Cepeda, of the Atlanta Braves, also connected three consecutive homers in an 8–3 victory over the Chicago Cubs.

• August 1 – At Atlanta–Fulton County Stadium, Willie Stargell of the Pittsburgh Pirates hits three doubles and two home runs in the Pirates' 20-10 win over the Atlanta Braves. He becomes the third player in modern-day Major League history to collect five extra-base hits in one game, Lou Boudreau and Joe Adcock having done so in 1946 and 1954 respectively. Amazingly, this game was nationally broadcast, and the trivia question early in the game was to name the two players who had gotten five extra-base hits in a game. Bob Robertson also collects five hits for the Pirates, including a home run; not until Andrew McCutchen and Garrett Jones in 2010 will two Pirates collect five hits each in the same game.
• August 11 – Philadelphia's Jim Bunning beats the Houston Astros 6-5 to become the first pitcher to win 100 games in both leagues since Cy Young.
• September 3 – Billy Williams of the Chicago Cubs asks to be kept out of the lineup, snapping his National League record of 1,117 consecutive games played. His record was broken in 1983 by Steve Garvey.

• September 16 – Minnesota Twins pitcher Bert Blyleven strikes out the first six California Angels batters of the game, and ties a major league record. Blyleven will finish the game with ten strikeouts, but take the 5-1 loss.
• September 21 – At Oakland–Alameda County Coliseum, Vida Blue of the Oakland Athletics no-hits the Minnesota Twins 6-0, the only baserunner coming on Harmon Killebrew's second-inning walk. The no-hitter caps a season that witnesses four no-hitters, all pitched in California-based Major League stadiums; Candlestick Park is the only one of the five not to have a no-hitter pitched in it. It is also the second time in three seasons an Athletic pitcher has no-hit the Twins, who were on the losing end of Catfish Hunter's perfect game in 1968.

• October 1 :
  • Vic Davalillo of the St. Louis Cardinals breaks the National League single-season pinch hitting record and ties the Major League record with his 24th pinch hit of the year.[2][3]
  • The Philadelphia Phillies defeated the Montreal Expos 2-1 in 10 innings in the final game at Shibe Park (Connie Mack Stadium). The occasion was marred by people literally dismantling the stadium while the game was still in progress. A special post-game ceremony — including a helicopter delivery to Veterans Stadium of home plate — was cancelled.[4]
• October 15 – For the third time in the 1970 World Series, the Baltimore Orioles overcome a 3–0 deficit to bury the Cincinnati Reds 9–3, and win the World Championship four games to one. Frank Robinson and Merv Rettenmund each homer and drive in two runs. Third baseman Brooks Robinson, the "human vacuum cleaner", easily wins the Series MVP award.

• November 21 - New York Mets outfielder Tommie Agee became the first non-pitcher to win a Gold Glove in both leagues. The New York flycatcher also won the honor with the Chicago White Sox during his 1966 rookie of the year season.
• November 25 – New York Yankees catcher Thurman Munson receives 23 of 24 first-place votes and is named American League Rookie of the Year. Munson batted .302 with six home runs and 53 RBI during the regular season. Cleveland Indians outfielder Roy Foster (.268, 23, 60) is also named on a first place ballot.
• November 27 – Pitcher Carl Morton, who posted an 18-11 record with 154 strikeouts and a 3.60 ERA for the last-place Montréal Expos, receives the National League Rookie of the Year Award. Morton beats out Cincinnati Reds outfielder Bernie Carbo, who hit .310 with 21 home runs and 63 RBI.
