Events
- June 8 - At Veterans Stadium, the visiting Pittsburgh Pirates score 10 runs in the top of the first inning against the Philadelphia Phillies, the last three coming on a Barry Bonds home run. As the Phillies come to bat in the bottom of the first, Pirate broadcaster Jim Rooker unwittingly says on the air, "If we lose this game, I'll walk home." Both Von Hayes and Steve Jeltz hit two home runs to trigger the comeback for the Phillies, who finally tie the game in the 8th on a wild pitch, then take the lead on Darren Daulton's two-run single and go on to win 15-11. After the season, Rooker conducts a 300-plus-mile charity walk from Philadelphia to Pittsburgh.
- October 9 - After 43 years on the air, NBC concludes its run as the number one over-the-air television broadcaster for Major League Baseball games.
- October 17 - Game 3 of the World Series is postponed due to the Loma Prieta earthquake, which struck immediately before the game was set to begin. It would be rescheduled for ten days later, October 27.
