NORTON, Mass. — The victories keep piling up for Justin Thomas, and all that does is make him want more.
In a Labor Day finish that was harder than the final margin suggested, Thomas kept his patience when Jordan Spieth took a brief lead and Marc Leishman built a two-shot lead at the turn. Keeping his mistakes to a minimum, Thomas outlasted them both by closing with 5-under 66 for a three-shot victory in the Dell Technologies Championship (scores, 2C).
He started the PGA Tour season at No. 34 in the world with all of one PGA Tour victory. He won for the fifth time Monday and is now No. 4 in the world. Barring Spieth running the table for the rest of the FedEx Cup playoffs, Thomas seems to be a lock to be voted PGA Tour player of the year.
"I have two events left. I have two more opportunities to win," said Thomas, who finished at 17-under 267 overall. "And I'd love to make it six or seven wins."
Spieth wasted a birdie-eagle-birdie-birdie start by missing the 14th green with a 5-iron for bogey. Needing eagle to stay in it on the par-5 18th, Spieth pushed a 4-iron into a tough lie in the bunker, blasted over the green and made bogey for 67. He still moved to No. 1 in the FedEx Cup with one more event before the $10 million prize is decided at the Tour Championship.
Leishman, who went into the round tied for the lead with Thomas, shot 70 and finished four strokes back.
