In his first season as the full-time closer for the Dodgers, Broxton was selected to the National League All-Star team. However, he was unable to play in the Game due to injury. His final regular season record was 7–2 with a 2.61 ERA, 36 saves and 114 strikeouts. Despite his accomplished season, he suffered a costly blown save in Game 4 of the 2009 National League Championship Series against the Philadelphia Phillies when he walked Matt Stairs, hit Carlos Ruiz with a pitch and then allowed a two out/two run walk off hit by Jimmy Rollins.
