Manager Chip Hale said Monday that Ray will be Arizona's fifth starter in the rotation, Nick Piecoro of The Arizona Republic reports.
Ray was the favorite for the last spot in the rotation and Hale's proclamation Monday only cements it. The 24-year-old started in 23 games last season, accruing a 5-12 record with an ERA of 3.52, although he could be supplanted by top prospects Braden Shipley or Archie Bradley at some point in the summer.
