Not to drag this too much into a Milone discussion, but I'll be really curious to watch how he does on the road this year. I think he is a great fit for the Oakland Mausoleum and perhaps Safeco but I want to see him in less flyball-friendly environments. Rosenbaum, if he is a true GB pitcher, might have an act that can play in more places.
He looks like another guy advanced stats may not like. His ERA is around 1.67 and his SIERA is 5.28 this year (OK, it's only 16.2 innings). Probably has to do with more walks than Ks, a lot of contact, and abnormally low BABIP. Last year, not so much a split. Check his stats at Minor League Central in the helpful links for the Farm.http://www.minorleaguecentral.com/player?pid=572095
