It's spelled Nolin in case people can't find him. He's one of our top pitching prospects after all the trades this offseason. I suppose they think he's ready, but then again with the Romero and Ramon Ortiz above him on the pecking order it doesn't really say much that they think he's ready for the show, even if on a brief audition. It would take at least a couple starts before I'd even bother stashing him.
EDIT: Fangraphs article
on Nolin from a few days ago.
