DALLAS • Jason Day made the most of a frantic moving day at the AT&T Byron Nelson golf tournament on Saturday by firing a seven-under 63 in the third round to move within two shots of leader James Hahn at TPC Las Colinas in Texas.

The world No. 4 Day began nine shots off the pace but made a run of five birdies in a row from the seventh hole and crowned a brilliant round with a 60-foot birdie putt at the par-three 17th hole to reach 200 for the tournament.

Hahn made three birdies on each nine in a bogey-free 64 to grab the 54-hole lead at 198 in his quest for a third PGA Tour victory.

"I played well out there. Overall it was a good day," said Hahn.

"It is really close. One putt here or there. You need good breaks to happen to keep the momentum going and I did that today."

Regarding his lead, Hahn also said he would not have a sleepless night, even though there were a dozen players within five strokes.

"Tell me what my tee time is tomorrow and I'll just show up," he said.

"There's a lot on the line but I feel like when I'm on the golf course there's a different animal that comes out and I get very competitive."

Billy Horschel, the 2014 FedExCup champion, was alone in second place one shot back at 199 after birdies at the last three holes, including a holeout from the greenside bunker at the 17th hole for his 66.

Second-round leader Jason Kokrak, who led by five strokes after firing a 62 on Friday, moved in the wrong direction - shooting a two-over 72 marked by a triple-bogey six at the par-three fifth hole.

Kokrak was tied for third with Day on 200 at the Four Seasons Resort in Irving, Texas.

Reigning US Masters champion and defending champion Sergio Garcia of Spain fired a 64 to finish on 202 and share sixth place with former Byron Nelson champion Jason Dufner (65) and Bud Cauley (68).

In Williamsburg, Virginia, Lexi Thompson, seeking her first win of the season, fired a two-under 69 on Saturday to maintain her lead after the third round of the LPGA Kingsmill Championship.

The American stands on 199 for a three-stroke lead over a crowded leaderboard of elite women golfers.

South Korea's Chun In Gee is second after shooting a 67 to reach 202.

Thompson had three birdies and made bogey on the par-three 17th hole for the second time this week.

"I am going to focus on my own game. Hopefully that brings me to where I need to be," she said.

World No. 1 Lydia Ko of New Zealand fired a 70 to join Australian Lee Min Jee (67) and South Korea's Kim Sei Young (66) in third, five shots adrift of Thompson.

Sweden's Madelene Sagstrom (68), China's Feng Shanshan (70) and American Danielle Kang (69) shared sixth at 206. REUTERS,
