Winning the 1989 Conn Smythe Trophy as the Stanley Cup Playoffs MVP, Al MacInnis played a crucial role in leading the Calgary Flames to their first Stanley Cup championship. As a defenseman, MacInnis demonstrated his powerful shot and playmaking abilities, amassing 31 points in 22 games, the most of any player that year. In Game 4 of the Clarence Campbell Conference Finals, on the road in Chicago, MacInnis scored the overtime winner with a powerful slapshot past Alain Chevrier, giving Calgary a 3-1 series lead. The Flames then closed out the series in the next game, advancing to the Stanley Cup Final against the Montreal Canadiens. During Game 4 of the Stanley Cup Final, with the Flames down two games to one, MacInnis skated the puck end-to-end before unleashing another big slapshot that beat Patrick Roy. This late third-period goal proved to be the game-winner, evening the series with the Canadiens. In the following game, MacInnis scored yet another crucial goal with a power-play slapshot in the final minute of the first period. This goal, his seventh of the playoffs, was also a game-winner. The dominant performance by MacInnis at both ends of the ice was pivotal in the Flames’ successful postseason run, cementing his legacy as a key contributor to their historic championship victory.
