I wouldn't even be opposed to a bigger retool. There are some tasty trade options with 1-2 years of team control after this year.
For sure you could sell - Civale, Cortes, Woodruff, Quintana, Hoskins, Bauers (if he is still hitting)
Could potentially sell - Payamps (if he continues to pitch how he has the last 2 weeks), Megill, Mears
Could sell if you're feeling like a 1-2 year retool - Peralta and Contreras
