The 2005 San Diego Padres season was the 36th season for the San Diego Padres. The 2005 team is noted as having the weakest record among division champions, finishing 82-80, the worst ever in a non-strike year. The NL West was weak in 2005, with all teams finishing below the .500 mark except the San Diego Padres, who only finished 2 games above the .500 mark. The closest team, the Arizona Diamondbacks, were 5 games back. Three teams in the Eastern Division finished with better records than San Diego but failed to qualify for the playoffs, such as the Phillies, who won 88 games and all swept the season series with the Padres. There had been some speculation that the Padres would be the first team in MLB history to win a division and finish below .500, but their victory over the Los Angeles Dodgers on September 30 gave them their 81st victory, guaranteeing a split record. They would be swept by the St. Louis Cardinals in the 2005 NLDS.
