Major league baseball final standings
- May 13 – Against the Philadelphia Phillies at Riverfront Stadium, Tony Pérez of the Cincinnati Reds becomes the oldest player to hit a grand slam. The shot comes in the sixth inning off Dave Rucker with Dave Concepción, Ron Oester and Dave Van Gorder on base and breaks a 3-3 tie; the Reds win by that 7-3 score. Pérez, who will celebrate his 43rd birthday the next day, breaks Honus Wagner's 70-year record as the oldest player to hit a grand slam; Wagner had done so on July 29, 1915, at 41 years, 5 months.
- June 11 – In a 26-7 romp over the New York Mets, Von Hayes of the Philadelphia Phillies becomes the first player in MLB history to hit two home runs in the first inning of a game. Hayes leads off the bottom of the first with a homer, then hits a grand slam later in the frame. They are the only two home runs hit in the high-scoring affair.
- July 2 – Pitcher Joe Niekro of the Houston Astros wins his 200th career game, 3–2 over the San Diego Padres. Joe and Phil Niekro join Jim Perry and Gaylord Perry as the only pitching brother combinations to each win at least 200 games.
- July 4–5 – In a bizarre game at Atlanta–Fulton County Stadium, the New York Mets beat the Atlanta Braves 16-13 in a 19-inning contest that features Keith Hernandez hitting for the cycle, Mets manager Davey Johnson being ejected, and the Braves coming back to tie the game twice in extra innings, most notably in the bottom of the 18th. Pitcher Rick Camp, a career .074 hitter batting only because the Braves have no position players left, shockingly hits a solo home run in the 18th to re-tie the game at 11-11. At the end of the game, even though the date/time is July 5, 3:15 am, the Braves go ahead and shoot off their scheduled Fourth of July post-game fireworks for the fans who endure to the end. Ironically, Camp struck out to end the game.
- July 11 – The Houston Astros' Nolan Ryan becomes the first pitcher to record 4,000 strikeouts, fanning Danny Heep in the sixth inning of Houston's 4–3 win over the New York Mets.
- July 15 – Dave Parker wins the first annual All-Star Home Run Derby.
- July 16 – The National League beats the American League 6–1 at Minnesota's Metrodome for its 13th win in the last 14 All-Star Games. The San Diego Padres' LaMarr Hoyt allows one unearned run in three innings and is named MVP.
- July 20 – Darryl Strawberry collects seven RBIs in the New York Mets' 16-4 victory over the Atlanta Braves at Shea Stadium.

- September 3 – At Tiger Stadium, Reggie Jackson of the California Angels becomes the first player to hit 100 home runs for three different teams. He hits the milestone home run off Detroit Tiger Bob Stoddard in the ninth inning of the Angels' 14-8 loss; he had homered off Dan Petry earlier in the game, in the fourth inning. Jackson had hit 269 home runs with the Kansas City/Oakland Athletics and 144 with the New York Yankees.
- September 8 – Pete Rose inserts himself into the Cincinnati Reds' lineup as a late addition, and picks up two singles, the second of which gives him 4,191 hits in his career, tying him with Ty Cobb for the career record. Being that the game is at Wrigley Field, the game is eventually called because of darkness after nine innings, resulting in a rare 5-5 tie.
- September 11 – Eric Show of the San Diego Padres goes down in history for pitching Pete Rose's historic 4,192nd career hit; a line drive single to center field. It breaks the tie for the career record which Rose shares with Ty Cobb since September 8.
- September 22 – At a hotel bar in Baltimore, the New York Yankees' pitcher Ed Whitson and manager Billy Martin get into a heated argument that spreads to other parts of the hotel. An ensuing fistfight results in Martin suffering a broken arm and bruised right side, while Whitson suffers a cracked rib and a split lip.
- September 24 – At Wrigley Field, Andre Dawson of the Montreal Expos (a future Cub) joins Willie McCovey as the only players to hit two home runs in the same inning twice in their careers. The two home runs come in a 12-run fifth inning that gives the Expos a 15-2 lead against the Chicago Cubs. The Expos hold on to win 17-15 after nearly squandering the 13-run lead, as the Cubs score 13 runs in the last four innings, including five in the ninth; the final out is recorded with the tying run at bat. Dawson also hit two home runs in the third inning of the Expos' 19-0 pounding of the Atlanta Braves at Atlanta–Fulton County Stadium on July 30, 1978.
- October 1 – Ron Darling and John Tudor duel for nine and ten innings, respectively, in this crucial series opener between the New York Mets and St. Louis Cardinals. An 11th inning solo home run by Darryl Strawberry off Ken Dayley is the deciding factor in the Mets' 1-0 victory at Busch Stadium.
- October 6 – Phil Niekro of the New York Yankees becomes the second pitcher this year to record his 300th career win, in a 6-0 shutout of the Toronto Blue Jays.

- October 27 – The Kansas City Royals burn out the St. Louis Cardinals 11–0 in Game Seven of the 1985 World Series to become only the sixth team to rally from a 3-1 deficit and win the WS. Bret Saberhagen pitches the shutout and wins the Series MVP honors.
