The LA Angels success from 2002-2009 which saw them win a World Series and five AL West titles was due to many things, but the one constant was the Angels bullpen. Names like Troy Percival, Scot Shields, Francisco Rodriguez, Brendan Donnelly were key contributors to the Angels success.
However, since 2010 the Angels bullpen has had its ups and downs which has been one of the reasons the team has not been nearly as successful since then. With Joe Smith gone and Huston Street showing signs of age the Angels bullpen is in dire need of a facelift.
