• January 29 – Los Angeles Dodgers catcher Roy Campanella suffers a broken neck in an early morning auto accident on Long Island. His spinal column is nearly severed and his legs are permanently paralyzed. Campanella will never play for the Dodgers after their move to Los Angeles, although a newspaper story (showing a picture of him wearing a Brooklyn cap) describes him as being of the Los Angeles Dodgers.
• February 4 – The Baseball Hall of Fame fails to elect any new members for the first time since 1950.

• April 15 – In the first Major League Baseball game played on the West Coast, Rubén Gómez of the San Francisco Giants hurls an 8–0 shutout against the Los Angeles Dodgers. Giants' shortstop Daryl Spencer hits the first Major League home run on the Pacific Coast. A park-record 23,192 fans pack San Francisco's Seals Stadium to witness the historic game.
• April 25 – The Dodgers set a record for the most fans at a regular season night game as 60,635 fans are on hand to see the Dodgers defeat the St. Louis Cardinals 5–3.
• May 13 – Stan Musial of the St. Louis Cardinals gets his 3,000th career hit, a pinch-hit double off Moe Drabowsky in the sixth inning of a 5–3 Cardinals victory over the Chicago Cubs at Wrigley Field.
• May 23 – Willie Mays hits his 200th career home run, a two-run shot off Warren Spahn in the ninth inning of a game against the Milwaukee Braves at County Stadium. The home run drives in the decisive runs of the game, as the San Francisco Giants down the Braves, 5–3.

• September 14 – The New York Yankees sweep a doubleheader against the Kansas City Athletics, 5–3 and 12–7 (14 innings), clinching their fourth straight American League pennant.
• September 20 – Hoyt Wilhelm of the Baltimore Orioles strikes out eight while throwing a no-hitter against the New York Yankees.
• September 21 – The Milwaukee Braves clinch their second consecutive National League pennant with a 6–5 victory over the Cincinnati Reds, thus ensuring a Yankees-Braves World Series for the second straight year.

• October 8 – The New York Yankees win the 1958 World Series handily as Moose Skowron's 3-run home run off Milwaukee Braves pitcher Lew Burdette in the 8th inning puts Game 7 on ice, 6–2. The Yankees became only the second team to come back from a 3–1 deficit to win a best-of-seven World Series, joining the Pittsburgh Pirates, who did it in the 1925 World Series. (The Boston Americans/Red Sox came back from a 3–1 deficit to win the first World Series in 1903, a best-of-nine series.) Milwaukee's Eddie Mathews strikes out for the 11th time, a record that will stand until 1980, when broken by Willie Wilson of the Kansas City Royals. The Braves' 53 strikeouts are also a new World Series record. This is Casey Stengel's 7th world championship, tying him with Joe McCarthy for the most Series won.

CBS and NBC aired weekend Game of the Week broadcasts. NBC began airing a special regional feed of its games in the southeast. The All-Star Game and World Series also aired on NBC.
