I don't know how I feel about Shields, honestly. He does have a track record in the AL East, but his HR proneness is highly concerning, especially since he's now in the NL West pitcher's dream division and he's still giving up HR's.
I'd rather target Quackenbush if we're going for a pen arm, honestly. I don't wanna give up that much for a big name, even if it is Kimbrel. Osuna is fine.
