Regular season

 * Willie Upshaw became the first Blue Jay to get over 100 RBIs with 104.
 * On August 4, 1983, New York Yankee Dave Winfield, while warming up before the 5th inning of a game at Toronto's Exhibition Stadium, accidentally killed a seagull with a thrown ball. He doffed his cap in mock sorrow. Fans responded by hurling obscenities and improvised missiles. After the game, he was brought to the Ontario Provincial Police station on charges of cruelty to animals and was forced to post a $500 bond before being released. Quipped Yankees manager Billy Martin, "It's the first time he's hit the cutoff man." The charges were dropped the following day. For years afterward Winfield's appearances in Toronto were greeted with loud choruses of boos, but he later became a fan favorite when he joined the team in 1992.
 * During an August 24, 1983 game, Baltimore Orioles pitcher Tippy Martinez picked off three Toronto Blue Jays baserunners in one inning. The baserunners were Barry Bonnell, Dave Collins and Willie Upshaw.
