The Rockies began play as an expansion team for the 1993 season, and played their home games for their first two seasons at Mile High Stadium. Since 1995, they have played at Coors Field, which has earned a reputation as a hitter's park. The Rockies have qualified for the postseason five times, each time as a Wild Card winner. In 2007, the team earned its first (and only) NL pennant after winning 14 of their final 15 games in the regular season to secure a Wild Card position, capping the streak off with a 13 inning 9-8 victory against the San Diego Padres in the tiebreaker game affectionately known as "Game 163" by Rockies fans. The Rockies then proceeded to sweep the Philadelphia Phillies and Arizona Diamondbacks in the NLDS and NLCS respectively and entered the 2007 World Series as winners of 21 of their last 22 games. However, they were swept by the American League (AL) champions Boston Red Sox in four games.
