Tony Barnette
After posting a 2.09 ERA and a 1.16 WHIP in 2016, Barnette fell off to a 5.49 ERA and 1.50 WHIP this season. Barnette, who turns 34 in November, was better in the second half. But was he good enough to convince the Rangers to pick up a $4 million option? That might seem to be an uncertain proposition, although the Rangers don't seem to be in position to discard pitching and relievers have a tendency to run hot and cold.
Austin Bibens-Dirkx
He was a great story, finishing 5-2 with a 4.
