There is way too much hope that Thornburg regains his 2016 form IMO. If he isn't dominant, this bullpen is worrisome. Kelly and Barnes are more of 6/7 inning guys and shouldn't be pitching in such high leverage situations. They are very shaky and completely lose the zone at times.
Do you really want him diving for a ball he likely doesn't catch, and have it result in a walk off inside the park home run? You don't risk that there.
He was solid as always, only run scored on a bloop double that Mookie easily catches if he's out there, but JD Martinez misplayed an out into an XBH. Like all of our starters, Cora pulled him early (5 innings, 92 pitches).
