  Regular season

• Joe Carter set a club record for most RBIs in a season.
• July 12, 1990: Jack McKeon, holding the dual positions of general manager and field manager of the Padres, turns over the managing portfolio to one of his coaches, Greg Riddoch, during the All-Star break. The Padres are 37–43 and in fourth place in the NL West at the time of McKeon's resignation.
• July 25, 1990: Roseanne Barr performed a controversial rendition of the "Star Spangled Banner" before a game against the Cincinnati Reds. As she later reported, she was initially having trouble hearing herself over the public-address system, so she was singing as loudly as possible, and her rendition of the song sounded "screechy". Following her rendition, she mimicked the often-seen actions of players by spitting and grabbing her crotch as if adjusting a protective cup. Barr claimed she had been encouraged by baseball officials to "bring humor to the song". The song and the closing routine offended many in the audience, and it was replayed frequently on television, drawing further attention to it.
• September 23, 1990: Ten weeks after stepping down as field manager, McKeon is fired from his general manager position by the Padres' new ownership group. He had led the San Diego front office since July 1980 and had acquired many of the players who led the team to its 1984 National League pennant. He is replaced by New York Mets executive Joe McIlvaine.
