Wolff shot his second straight 8-under 64 to move into position for his second PGA Tour victory.
He was at 19-under 197 at Detroit Golf Club.
Armour and Bryson DeChambeau were tied for second after 67s.
Wolff made a 14-foot eagle putt at the 559-yard, par-5 14th to pull into a tie with Armour at 17 under, and added birdies on the par-3 15th and par-5 17th. He finished with the eagle, nine birdies, five pars and three bogeys.
