The 1989 Toronto Blue Jays season was the franchise's 13th season of Major League Baseball. It resulted in the Blue Jays finishing first in the American League East with a record of 89 wins and 73 losses. The Blue Jays' ace pitcher Dave Stieb led the staff with 17 victories, and the team was offensively buoyed by the league's home run king Fred McGriff. Toronto won the AL East pennant in the final weekend of the season against the favored Baltimore Orioles. The Blue Jays lost the ALCS in five games to the eventual World Series champion Oakland Athletics. It was the team's last season at Exhibition Stadium, before moving to SkyDome halfway into the season. The Blue Jays hit eight grand slams, the most in MLB in 1989.

Regular season

The regular season would represent a turning point for the Blue Jays in many different ways. The Blue Jays started the 1989 season in Kansas City against the Royals. Behind the pitching of Jimmy Key, the Jays won the first game of the season 4–3. The rest of the month would result in a losing record for the Jays. After the first month of the season, the Blue Jays had 10 wins and 20 losses and sat 6.5 games behind the Baltimore Orioles in the standings. The result was that Pat Gillick made his first trade in 605 days. On April 30, Gillick sent Jesse Barfield to the New York Yankees in exchange for Al Leiter. The reason for the deal was that management was convinced that Rob Ducey was ready to be an everyday outfielder. The spot eventually went to the surprising Junior Felix that year, and Ducey never became the everyday player the Jays imagined him to be. The Blue Jays had never fired a manager in the middle of the season. After the Jays were swept by the Minnesota Twins in a three-game series, including a 13–1 loss in the final game of the series, the Jays had 12 wins and 24 losses. The Jays had also lost 15 of their last 19 games. Gillick decided that a change was needed. On Monday, May 15, Jimy Williams had become the first Jays manager to be fired in mid-season. Williams would be replaced by Cito Gaston, the first black manager in the history of the franchise. The Blue Jays' last game at Exhibition Stadium was against the first team they played there, the Chicago White Sox. From there, the Blue Jays opened the new Skydome with a loss to the Milwaukee Brewers. On September 30, they clinched the American League East division title at the new ballpark.
