Gray (abdomen) has been activated off the 15-day disabled list and he will get the start Friday against the Dodgers, Nick Groke of the Denver Post reports.

It was announced Thursday that Gray would get the start for the Rockies' series opener against Los Angeles, but the club hadn't made it official until it activated him from the DL. Gray will take the roster spot of Miguel Castro, who was placed on the disabled list due to right shoulder inflammation. Friday marks Gray's first start of the season, and he'll be put to the test right off the bat as he'll be facing an explosive Dodgers lineup.
