De La Rosa will start the Diamondbacks' fourth game of the regular season, Steve Gilbert of MLB.com reports.
As expected, De La Rosa will follow Zack Greinke, Shelby Miller and Patrick Corbin in the rotation. Robbie Ray, Zack Godley and Archie Bradley are competing for the fifth spot. De La Rosa will need to improve on last year's 4.67 ERA and 1.36 WHIP to be fantasy relevant in 2016.
