This did not usher in a prolonged period of success for the Padres, who failed to achieve a second postseason appearance until 1996, and after a disappointing 1997 they rebounded again with a franchise-best 98 wins and reached the World Series only to face another exceptionally formidable opponent in the late-1990s Yankees dynasty. The Padres yet again faltered, but achieved four consecutive winning seasons for the only time in franchise history between 2004 and 2007 without winning more than one playoff game. The Padres have not played in the postseason since 2006 despite only the fourth 90-win season in franchise history during 2010.

Based on this passage, when was the last time the padres went to the playoffs? Let's think fast. Stream of consciousness:
To answer the question, consider the following: The Padres have not played in the postseason since 2006 despite only the fourth 90-win season in franchise history during 2010. So the final answer is 2006.
