Ray appears to be locking down the No. 5 spot in the Diamondbacks' rotation, the team's official site reports.
Ray entered camp the favorite to win the job, and his performance is backing that up. He has a 1.86 spring ERA, while top competitors Archie Bradley and Zack Godley are at 9.00 and 11.88, respectively. Diamondbacks manager Chip Hale said a decision hasn't been made but added that Ray is "pitching well enough to have that job."
