6 years agoTampa Bay Rays relief pitcher Diego Castillo was added to the major league roster Tuesday. Castillo's call-up came as Chris Archer was placed on the disabled list. Castillo has been lights-out at Triple-A this season. In 26 1/3 innings, he has 32 strikeouts, seven walks, an ERA of just 1.03 and four saves to his name. At this stage, his role or time frame with the Rays is unknown. However, if Castillo pitches well, he could have a shot at getting saves in the majors, as the Rays have still not settled on a closer after trading Alex Colome. For now, Castillo's value is in AL-only leagues, but if he gets off to a hot start, he could creep into mixed league relevance.--Ben Rolfe
