Trying to figure out how many '100 mph arms' the Astros have in the system (MLB and MiLB). They don't have to sit at 100 mph, rather, just touch 100 on occasion (even on rare occasion). Rhiner Cruz can get there, as can Lance McCullers, Jr. I think there are one or two more, but can't recall who...
Via twitter: appears Folty and Cosart get there occasionally...
