Young will be called up from Triple-A Reno to start Thursday against the Giants, Julia Stumbaugh and Nick Piecoro of the Arizona Republic report.
Diamondbacks manager Torey Lovullo confirmed the left-handed Young will be ticketed for the big-league rotation for the series finale. Young has made eight starts in the Pacific Coast League this season, posting a 5.79 ERA with 39 strikeouts in 32.2 innings. Arizona is desperate for starting pitching, and Thursday's outing will present an opportunity for the 25-year-old Young to be part of the rotation going forward until Luke Weaver (forearm) is ready to return.
