Robbie Ray: Robbie Ray developed into a second ace behind Zack Greinke this year. The electric southpaw had the kind of year that might make Greinke and his large contract expendable this winter. A payment of $4.2 million for a guy of his value is a great bargain for Hazen and company.
Jake Lamb: Lamb had a poor second half, and he still has trouble hitting lefties. But, Lamb finished seventh in the NL in RBI (105), he hit 30 home runs and was one of two third baseman with 85+ runs and 85+ walks. There is no chance the D-backs will let Lamb go, but his second half performance could push his arbitration projection below $4.7 million.
David Peralta: David Peralta cemented his value with his production in the leadoff spot. He is the table setter that kept the D-backs high powered lineup going. The D-backs were 30-24 when he hit leadoff.
Patrick Corbin: Corbin struggled in the first half, but he cemented his value in the second half and a place in the 2018 rotation. In 15 starts after the All-Star break, he was 8-4 with a 3.26 ERA, a .252 opponents average and 83 strikeouts. Corbin was tied for first with eight wins and sixth in innings (88.1).
Taijuan Walker: Walker finished with a career-best 3.49 ERA, and his .247 opponents average tied a career high. The right hander struck out 146 batters, the second-most of his career and eight of his nine wins came against the NL West.
