Merged our two SP threads since they'll be talking about filling the same roles. I've been trying to think through some buy-low style acquisitions, the idea being that there's some reason to hope they'll be worthwhile, and would have a cheap enough acquisition cost to allow for the best possible offseason elsewhere(spending on Darvish, creating a super bullpen, etc). One theme with all of these options is that they continue with the Cubs' philosophy of wanting to control the strike zone. We know Bosio was canned at least in part for the inability for the relievers to throw strikes, all of the Cubs rotation stalwarts had sub-8% BB%, and I'd guess that's a big reason why they don't commit to Montgomery as a rotation option. Chris Tillman ++ Tillman is only a year removed from 4 consecutive years of average pitching. He was horrifically bad this year, but his stuff didn't really deteriorate, and finally getting him away from Baltimore's pitching environment with the AL to NL bump too could help. He's a FA so he's certainly available and he won't be expensive. -- Tillman was a nightmare in 2016 so you're taking a pretty huge gamble on him. His vertical release point has been in slow decline for a while and he missed some time with a shoulder injury this year, although you aren't hoping that Tillman is any sort of long term answer anyway. Kendall Graveman ++ Graveman has been a pretty average pitcher on the mound the last couple years. Even in his best case scenario he's not really someone you anticipate starting a playoff game, so he's not likely to be super expensive in trade. He's under team control for 3 years and would get a lift from moving from AL to NL. -- Graveman missed a big chunk of this year with a shoulder injury and his vertical release point looked the part too. The 3 years of team control don't mean much if he's about to go under the knife. He's super reliant on his defense because he doesn't strike out anyone even in this environment. Jeremy Hellickson ++ Hellickson was a 3 win pitcher just a year ago, and there aren't any huge indicators that his stuff is falling off. He has the Maddon/Hickey connection from his work as a mostly average pitcher in Tampa. He has always done a good job of BABIP suppression, and he's a FA and not likely to be an expensive one. -- Hellickson was terrible this year, his K rate fell, his HR rate spiked, and his ground ball rate fell. An optimist might see that as something mechanical that's fixable by working with old friend Hickey, a pessimist might see decline coming early for Hellickson since he's never had overwhelming stuff. Jordan Zimmermann ++ Zimmermann is presumably still the same human being that put up 19 fWAR in 5 years for Washington. He's still only 31, and his 2017 was pretty fluky from a BABIP perspective considering his stuff wasn't any worse than it was in 2016. Getting back to the NL and possibly working with Hickey who might be able to get more out of his 4 seamer may help. Detroit would love to be out from his contract so the player cost would be basically nil. -- Zimmermann's stuff isn't worse than it was in 2016, but it's definitely lost a tick from his Washington days, so even with the bad luck, you're talking about being similar to his 2016 which is still solidly below average even after considering AL/NL. His contract is also a huge albatross(3/74, 22M per towards luxury tax), so you'd have to make that more palatable in some way by getting another player of interest, getting money from Detroit, or trading Heyward/Zobrist. Erasmo Ramirez ++ Ramirez was turned around with Hickey in Tampa and put in a solid 2016. His decline seems related to dropping his 4 seamer, which would also seem to correlate to some divergence in approach between Tampa and Hickey's preference. He has 3 years of team control, would get the AL to NL bump, and while he wasn't terrible in Seattle, he wasn't really above average and Jerry DiPoto loves his trades. He's also capably served as a swing man in the case he gets supplanted in the rotation -- Ramirez hasn't held up to a full year's workload, which isn't the worst thing in a speculative 5th starter, but worth considering. He hasn't been super valuable, but the Mariners need pitching more than anything so getting rid of Ramirez probably isn't at the top of the todo list and might not be exorbitantly cheap.
