This will be the 12th tiebreaker in the history of the majors.
1946 - The Dodgers and Cardinals were tied with two games left in the season. They both won on the last Saturday of the season and then both won on the final Sunday to force the first tiebreaker playoff. The Cardinals won 2games to none.
1948 - Cleveland led both the Yankees and Red Sox by one game with two to play. On the final Saturday (October 2), the Red Sox beat the Yankees 5-1 to eliminated New York as Cleveland won. Boston forced a tie on the final Sunday with a 10-5 win over the Yankees and Cleveland lost to Detroit 7-1. Cleveland won the one game playoff at Fenway, 8-3.
1951 - Branca pitched to one batter in the 9th
1959 - In a weird and wild pennant race, the Dodgers and Braves both passed up the Giants in the final week. The Braves caught the Dodgers on the final Saturday (September 26), and both teams won on Sunday, with the Dodgers beating the Cubs 7-1 at Wrigley and the Braves beat the Phillies, 5-2 in Milwaukee. The Dodgers won the playoff in twogames.
1962 - The Dodgers led the Giants by 1 1/2 games with two to play. The Dodgers lose both games (to the Cardinals) while the Giants won three games, including a doubleheader sweep, against Houston. Giants win the playoff in three games. Three very, very, very trying games.
1978 - HR: Dent (5,7th inning off Torrez 2 on 2 out);
1980 - The Dodgers come into the final weekend down three games to Houston with three to play against the Astros at Dodger Stadium. The Dodgers win all three in dramatic fashion. And then lose the tiebreaker on Monday in incredibly undramatic fashion.
1995 - The Mariners lead the Angels by two games with two left and lose both to Texas while the Angels win two against Oakland. The tiebreaker is ... not exciting.
1998 - The Cubs and Giants are tied on the final day. The Cubs lose in Houston, 4-3, in 11 innings. The Giants blow a chance at a playoff spot when Robb Nen gives up a game-ending home run to Neifi Perez at Coors Field. The Rockies win 9-8. The next day, the Cubs survive a 3-run ninth by the Giants in a 5-3 victory.
1999 - On the final day, the Astros lead the Reds by one game in the Central. The Reds are tied with the Mets for the wild card. Houston beats the Dodgers 9-1 to win the Central. The Mets beat the Pirates 2-1 on a game-ending wild pitch by Brad Clontz. The Reds wait out a lengthy rain delay in Milwaukee to win 7-1. Al Leiter of the Mets throws a 2-hitter against the Reds at Cinergy Field in a 5-0 win.
2007 - The Rockies are in first place for only one day, April 6. They don't move into a tie for playoff position until the last day of the season, September 30, when they catch the Padres. The Rockies outlast the Padres, 9-8, in 13 innings at Coors Field. The Rockies use 10 pitchers in the game, with Ramon Ortiz getting the win, the only win he ever had as a Rockie.
