Diaz Big Part of Louisville Bullpen

30 year-old Jumbo Diaz is a classic example of a minor league journeyman. He's now in his twelve season and working in his fifth organization. Previously the most memorable thing about his was his physique which was often well north of 300#. He lost a lot of weigh coming into this season and throwing a high-90's fastball that is worthy of attention.
