Nice to avoid the sweep
I would hang onto Edwards .. he had a good year and is young and cheap (by baseball standards) ... he can bounce back.
Duensing is decent enough, Strop is good,
Davis is a FA, so they need to sign him. I think they are going to try to sign shorter term pitchers given Baez, Russell, Bryant, Contreras are all going to be arbitration eligible soon and they will command some big contracts. Though Montero, Jake, and Lackey go off the books after this year, Zorbrist has one more year to go on his contract, so that will help.
Harper has one more season, then he is a FA
Montgomery was okay when he started this year ... he could be a decent enough 5th starter if the top 4 is good, which it should be with Hendricks, Lester, and Q. I am guessing they will try for someone like Lackey )not Lackey, but a vet who will sign a 1 or 2 year deal) to be the #4 ... then there are guys like Butler and Tseng at Iowa who maybe get a shot at #5 .. not sure either of them are better than Montgomery though
