1981 National League Championship Series

Los Angeles won the series, 3–2.

Tuesday, October 13, 1981, at Dodger Stadium in Los Angeles, California

The Dodgers took the first game of the series behind the strong pitching of starter Burt Hooton. For the first seven innings the game stayed close, with the only scoring coming in the second inning when the Dodgers got two runs on an RBI double by Ron Cey and a squeeze bunt by Bill Russell. Hooton and reliever Bob Welch made the 2–0 lead stand up until the eighth when the Dodgers broke the game open with three more runs on back-to-back homers by Pedro Guerrero and Mike Scioscia. The Expos got one run back in the ninth when Larry Parrish doubled home Gary Carter. But reliever Steve Howe came on for the Dodgers and got the final three outs to preserve Los Angeles' victory.

Montreal's Ray Burris helped even the series with a masterful complete game shutout in Game 2. The Dodgers managed only five singles against Burris, and their only real threats, in the sixth and ninth, were foiled by double plays. Typically in what would be a very low-scoring series, the Expos didn't do much more hitting against Dodger starter Fernando Valenzuela. But Montreal did manage to push across two runs in the second on RBI hits by Warren Cromartie and Tim Raines. Montreal added another run in the sixth, aided by Dusty Baker's error in left. Burris did the rest to notch his 3–0 victory.

Friday, October 16, 1981, at Olympic Stadium in Montreal, Quebec

Montreal got another superb pitching performance in Game 3, this time from Steve Rogers, to take a 2–1 lead in the series. Rogers allowed only a single run on a Ron Cey groundout after singles by Dusty Baker and Steve Garvey in the fourth. For a while it looked like Dodger starter Jerry Reuss might make that 1–0 score hold up. But Montreal finally rallied for four runs in the sixth on a run-scoring single by Larry Parrish and a three-run homer by Jerry White. Rogers easily preserved the 4–1 lead over the final three innings, and Montreal was now only one victory away from the World Series.

Saturday, October 17, 1981, at Olympic Stadium in Montreal, Quebec

For the first seven innings Game 4 followed the usual pattern of the series, with dominant performances from both starting pitchers. Montreal's Bill Gullickson allowed an unearned run in the third, after Bill Russell reached on Larry Parrish's error and scored on Dusty Baker's double. Los Angeles' Burt Hooton gave up the game-tying run in the fourth on another unearned tally, when Gary Carter reached on Ron Cey's error and scored on a single by Warren Cromartie. The starters yielded nothing more until the eighth, when Steve Garvey's two-run homer put the Dodgers up 3–1 and chased Gullickson. The Dodgers blew the game open with four more runs in the ninth, highlighted by Baker's two-run single. Hooton finally tired in the eighth but the Dodger bullpen got the last five outs and the series was even.

Monday, October 19, 1981, at Olympic Stadium in Montreal, Quebec

After a rainout (actually a snow/cold out) on Sunday, October 18, Olympic Stadium was only two-thirds full for Game 5 on a cold and drizzly Monday afternoon, which turned out to be the series' most dramatic contest. As usual in the series, the starting pitchers dominated, with the Dodgers' Fernando Valenzuela and the Expos' Ray Burris. Montreal broke on top with a single run in the first when Tim Raines led off with a double and eventually scored on a double play. The Dodgers tied the game in the fifth after Rick Monday singled, went to third on a Pedro Guerrero single, and scored on a groundout. Burris finally left the game in the eighth when the Expos pinch-hit for him. Montreal brought on their ace Steve Rogers to pitch the ninth, and with two out in the inning, he gave up a homer to Monday on a 3–1 count to put the Dodgers up 2–1. The Expos got a couple of two-out walks in the bottom of the ninth off Valenzuela, but Bob Welch came on to get the final out and send the Dodgers to the World Series. It would be the final postseason game played in Montreal and it would take another 31 seasons until the franchise returned to the postseason again as the Washington Nationals.

The date came to be known as "Blue Monday" by Expos' fans.[6][7] Expos' broadcaster Dave Van Horne described the loss as one of the lowest points in team history.[8]
