Rory McIlroy carded his lowest moving day score in more than 17 months after coming from out of nowhere to contend at the Dubai Desert Classic.
But by the time McIlroy finished his round he held the outright lead after posting a 9-under 63.
America's Young later carded a 1-under 71 to regain the lead at 14-under heading into the final day.
He is two clear of McIlroy and Poland's Adrian Meronk.
The Hojgaard brothers, Haotong Li, Thorbjorn Olesen, Tommy Fleetwood and Alex Fitzptrick are also inside the top-10 but appear too far back to mount a charge.
As for McIlroy, his third round was absolutely flawless.
He began with a birdie and picked up more strokes at 3, 7, 8 and 9. He birdied the 10th and 12th at Emirates Golf Club before signing off with an eagle at the final hole.
