Yeah, even if he's coming in as a long-man, it's gotta mean Marcum is out for an extended period of time. They seemed set to go with Fiers in that role. Maybe it means Fiers is sticking in the rotation, and Hernandez is long-man. Vice-versa wouldn't make sense, they'd just go with Thornburg if that was the case. They'd probably rather have Hernandez in the pen, and Thornburg starting in AAA, which actually would make sense.
