a rash of significant injuries to key players. After dropping seven games behind the Atlanta Braves on July 21, Philadelphia finished with an MLB-best record of 97–65. The streak included a 20–5 record in September, the Phillies' best September since winning 22 games that month in 1983, and an 11–0 run in the middle of the month. The acquisition of pitcher Roy Oswalt in early August was a key step, as Oswalt won seven consecutive games in just over five weeks from August 11 through September 17. The Phillies clinched the division on September 27, behind a two-hit shutout by Halladay. In Game 1 of the 2010 National League Division Series, Halladay threw the second no-hitter in Major League Baseball postseason history, leading the Phillies over the Cincinnati Reds, 4–0. (The first was New York Yankees pitcher Don Larsen's perfect game in the 1956 World Series.) Halladay's no-hitter was the fifth time a pitcher has thrown two no-hitters in the same season, and was also the first time that one of the two occurred in the postseason. The Phillies went on to sweep the Reds in three straight games. In the 2010 National League Championship Series, the Phillies fell to the eventual World Series champion San Francisco Giants in six games. Halladay was named the 2010 NL Cy Young Award winner. Before the start of the 2011 season, the Phillies signed pitcher Cliff Lee to a five-year deal, bringing him back to the team and forming a formidable rotation of Halladay, Lee, Hamels, Oswalt, and Blanton. Including Vance Worley, who replaced Joe Blanton due to injury. The rotation combined for a win–loss record of 71–38, and an earned run average of 2.86, the best in the majors that year. Commentators called it one of the best rotations ever assembled. Halladay, Oswalt, Lee, and Hamels were dubbed two nicknames by fans and media: the "Phantastic Phour" and "The Four Aces". On September 17, 2011, the Phillies won their fifth consecutive East Division championship, and on September 28, during the final game of the season, the team set a franchise record for victories in a season with 102 by beating the Atlanta Braves in 13 innings, denying their division rivals a potential wild card berth. Yet the Phillies lost in the NLDS to the St. Louis Cardinals—the team that won the National League Wild Card as a result of the Phillies beating
