LOS ANGELES (AFP) — Canadian Nick Taylor held a one stroke lead over American Sahith Theegala when darkness halted play in the third round of the PGA Tour's weather-disrupted Phoenix Open on Saturday.

The pair had completed six holes of the third round at TPC Scottsdale after getting through their second rounds earlier in the day.

Doug Ghim and Andrew Novak were both two shots off the lead while three-times major winner Jordan Spieth reached the turn at two-under for his round, moving him three behind Taylor.

The leaders will have 30 holes to get through on Sunday with organizers hoping the risk of frost in the morning does not add any further delays to the schedule.

A 3 1/2-hour rain delay on Thursday put the tournament behind schedule and frost on Friday added to the disruption.

Theegala had fired a seven under-par 64 to top the leaderboard after the second round but then returned to bogey the first two holes of his third round.

A birdie at the par-3 fourth, steadied him but Taylor took advantage to edge back in front, draining a 48 foot putt for birdie on the par-4 fifth.

Taylor had equalled the course record on Friday with his 11-under-par 60 and while he wasn't able to recapture that form in his second round, making bogey on the first hole, he recovered with birdies on the 10th and 17th to shoot 70.

The Canadian finished second in this event last year, missing out to Scottie Scheffler by two shots, before going on to win the Canadian Open in June.

"I feel like I just have good vibes here after last year. I played great last year and just got beat I felt like," he said.

"I wasn't probably expecting to shoot a 60 or something crazy low the first day, but I figure I have good energy here now, and a lot of years in a row I didn't.

"I wouldn't say it's unfinished business, but I'm definitely in good position to try to finish it off," he added.
