If - as mentioned plenty of times in separate places - the consensus targets are (not necessarily in order) a pen arm, a veteran starter, and a "big bat", there are going to be a ton of ways for AA to approach things...
Pen Arm - would be nice to have someone with closing experience from the right side (even though it's probably not entirely necessary with Martin around).
1.) You've got plenty of big-name targets, but with $20 million already committed to Smith and Martin, it's awfully tough to see AA making a play for someone like Colome, Treinen, Giles, Yates, or Hendriks IMO.
2) Given his age (and the market) it's tough to imagine many teams offering multiple years to Melancon - considering he's had a big payday, he might be open to taking a little less to stay put if most teams are going to tighten their belts as much as we think. If you could bring him back on a $5-$8 million deal, that would make the pen scary deep again. I don't see bringing Greene back as plausible unless his market collapses for some reason no one sees coming - he likely gets a multi-year offer from SOMEBODY.
3.) Almost impossible to imagine Oakland can hang onto all their guys - Hendriks is the sexy name, but both Soria and Petit are older guys who probably get 1 year deals. Either of them could probably be had in that $5 million range. Ian Kennedy probably represents another older option who probably doesn't get multiple years either.
4.) If another multi-year deal would be considered, I think Kela might be a nice, sneaky signing.
With Smith and Minter pretty much locked-in as the top two LHs and Matzek, Dayton, Newk, and Davidson as potential options as well (and the possibility they break Muller in in a pen role) it's just really hard to see them targeting a LH reliever.
Preference - re-sign Melancon and watch to see if one of the older guys like Soria, Kennedy, Greg Holland, Petit, Tommy Hunter, or Blake Parker slips through the cracks with everyone looking to get younger and pinch pennies.
Veteran SP - HAS to be someone on a 1 year deal, doesn't it?
1.) All but impossible to imagine AA's in a position to bid on Bauer whether he takes a 1 year deal or not. Gausman, Odorizzi, Stroman, Paxton, and Garrett Richards probably get multi-year deals even if they're not particularly expensive.
2.) Hang onto Folty - he isn't likely going to get much of a raise (if at all), and our people have gotten the look at him that no one else has.
3.) If Archer proves he's healthy he's probably the upside play on a 1 year deal. Another name that's not so sexy that I'd look at is Mike Leake - has always been a solid innings-eater. Mike Fiers might fit as that type too.
Preference - Leake on an $8-$10 million (or less) deal to chew up innings and buy that much more time for Newk/Touki/Wilson/Davidson/Muller. Keep an eye on Wood in the event his market tanks as another potential LH option if he'll sign a split deal.
Bat - probably as short-term as possible.
1.) Just can't see Ozuna coming back. Hope I'm wrong, but if bringing him back causes AA to have to go really cheap on the pen and rotation arms he's probably much better off spreading whatever money he can spend evenly. Freddie, Acuna, d'Arnaud, and Ozzie are going to make you dangerous enough without spending big. Springer would be "nice", but someone's probably going to give him a contract they'll regret too.
2.) Turner will be out there, but Riley's done enough to make you think there's no real reason to sign him and add another RH bat. Marte kinda gets in the way of Pache and Waters since he'll get a multi-year deal.
3.) Pay whatever raises Duvall and Dansby get in arbitration to give you the lineup flexibility you've had this year. While not ideal, Ozzie can hit in the middle of the order to break up a run of RH bats if he needs to.
Preference - sign Brantley to balance the lineup. He's already shown he can produce as an everyday DH, and while he may not hit 35 or 40 bombs like Ozuna or Springer he's still a *elluva hitter. He won't exactly be "cheap", but probably doesn't get the type of deal Ozuna does. You're going to shave off big chunks of payroll if you re-sign Melancon for half of what he's making, let Greene, Flowers, Markakis, Jackson, and Camargo walk, and replace Hamels with a much cheaper SP. Give him a 2 year deal with an option - that buys you the time you need to find out what you have in Waters. If he's as good as hoped, you can let Duvall walk after next season.
