"I don't care to belong to any club that will have me as a member." -- Groucho Marx
Arizona Diamondbacks reliever Jorge De la Rosa and Seattle Mariners starter Felix Hernandez are members of a club they'd rather not have the dubious distinction of belonging to. They are the only active pitchers in the major leagues to have played 13 seasons or more without a single playoff appearance.
The longest playoff drought for any active pitcher (14 seasons) belongs to De La Rosa. The native of Monterey, Mexico, made his big league debut with the Milwaukee Brewers in 2004 and has spent most of his career (2008-16) with the Colorado Rockies.
