There's still some pretty interesting bullpen guys out there who should come at a reasonable price, along with some intriguing wildcards.
Will Harris, McHugh (if the elbow is okay), Kintzler, Rondon, Cingrani all seem like pretty good targets.
Guys with worse peripherals but consistently good results include relievers like Cishek and Buchter.
Wildcard guys include relievers like Cody Allen (who, reading between the lines, is on a driveline/weighted ball program this offseason) and Holland. I'm sure I'm missing some.
I like our offseason so far, but we still need to fill a few holes.
