2019 depends on what 2018 looks like. But the Twins would be foolish not to try to keep him around, he is still a .370 OBP guy who should have 3.0-3.4 WAR this year. Plenty of value IMO, esp considering Vargas is nothing special at all thus far, and no other real DH in the system. Sano should be at 3B for next couple years as well. I'd guess, if he replicates 2017 next year , that he signs a 2 year contract (I can't see him wanting to go year to year) for about 5-6 mil a year. Worth it IMO
