Jon Heyman just tweeted that Pence remains at the top of the Phillies' list, with Carlos Quentin in second place, and that right fielder Dom Brown - who would immediately be slotted in Pence's place should this happen - may not be untouchable, anymore.
This makes perfect sense, because with Pence, the Phillies will have a right fielder for the next 2+ years. I don't understand why Brown would have been a sticking point, anyway.
