Belgium’s Thomas Detry shot 6-under-par 65 on Saturday to extend his lead through three rounds of the WM Phoenix Open in Scottsdale, Ariz.

Detry is at 18 under with a five-shot edge on four others going into Sunday’s final round. Daniel Berger (66), Jordan Spieth (67), Michael Kim (68) and Denmark’s Rasmus Hojgaard (65) share second place.

Detry, a 32-year-old seeking his first PGA Tour victory, had birdies on four of the first five holes of the TPC Scottsdale Stadium course and tallied three more to override his one bogey. His strong third round followed a 66 and 64 during the first two days of the tournament.

Hojgaard began the round on the back nine and drew closer to the lead after an eagle on the par-5 13th. He washed that away with a double-bogey on the par-5 15th but recovered to birdie his final two holes.

Maverick McNealy made a big move with a 63 — the best round of the day — to hold sixth place at 12 under.

World No. 1 Scottie Scheffler (68) is tied for 10th place at 10 under.
