A three-time All-Star with the Rockies, Brian Fuentes would find his niche when he became the team’s closer in 2005.  He would have three seasons where he would have over 30 Saves and would have 115 in total for the team.  As of this writing, he is definitely the best closer in franchise history.  

He signed with the Angels in 2009 and had his best season with an American League leading 48 Saves.
