Yes, I'd make that deal. You upgrade at SP, which you could use, without taking a huge hit to your OF. And you also sworn from Axford, who is going to be sharing saves with KRod, to Putz, who has the job to himself. Incarnation and Wiggs are incidental. Do it.
One hesitation is that you're losing your only real source of steals in Bourn. You could get SOME Of that back in Bonifacio, though, so I think Bourn/Axford for Hamels/Putz is fair. Is Hernandez on the wire? You might want to snag him to handcuff Putz, who's no spring chicken.
My only concern would be the loss of SB. If you can carry on without Bourn, make the trade. While I disagree that Axford will lose many save opportunities (I actually think he will get more), it isn't something to fret about.
Your team is not built around speed so I wouldn't be too concerned. You are likely in the middle or bottom of the pack in steals is my guess. No question you take this deal. Basically squares up to being Bourn for Hamels and that's a no brainer IMO
