Sergio Garcia put together a 6-under 65 on Sunday to extend his lead to two shots after three rounds of the Deutsche Bank Championship.
Garcia, an 8-time winner on the PGA Tour, ended 54 holes at 19-under-par 194. He matched the tournament's 54-hole scoring record that Louis Oosthuizen set last year.
Henrik Stenson carded a 66 to move into second place at minus-17. Steve Stricker and Graham DeLaet had two of the best rounds of the day, which helped them soar into a share of third.
Stricker eagled the last for an 8-under 63, while DeLaet birdied five of the last seven for a 9-under 62. They are tied at 16-under 197 at TPC Boston.
PGA Championship winner Jason Dufner (66) and Roberto Castro (68) share fifth place at minus-15.
The round was completed in near darkness after a lengthy weather delay earlier in the day. Some players had started their third rounds, but the long stoppage forced officials to erase that play and have players go out in threesomes of split tees.
Otherwise, the round would not have finished on Sunday. And with more bad weather forecast for Monday, final round tee times have been moved up in an effort to beat that inclement weather.
Garcia pitched his third at the par-5 second to 10 feet and he converted that for his first birdie of the day. After a pair of pars, he rolled in an 8- footer for birdie on No. 5.
The Spaniard parred four straight from the sixth. Garcia stuffed his approach at the 10th within three feet and knocked that in for his third birdie of the day.
Garcia birdied the 12th and 13th from four and eight feet out respectively. He found sand with his second shot at the par-4 14th. Garcia blasted to 11 feet, but 2-putted for bogey.
That dropped him into a share of the lead at minus-17 with Stenson. Garcia bounced back with an 8-foot birdie putt at the 15th to regain the lead. He reached the par-5 18th in two shots and 2-putted for birdie from 39 feet out to push his lead to two.
"Obviously, I'm very happy with the way it went. I felt like I played pretty good for pretty much most of the day. It got a little bit dark on the last hole," Garcia stated. "But I'm happy to be able to finish it off and finish it off with a birdie, obviously."
Stenson started his round with a 9-foot birdie putt at one and a 2-putt birdie at the second. He made his third birdie of the day at the fourth, he got up and down from just short of the green at the drivable par-4.
The Swede ran off six consecutive pars from the fifth. Stenson ended that run with a 17-footer for birdie at the 11th. He moved to 17-under with a 15-foot birdie effort at the 16th.
Stenson came up short at the 17th, but pitched to five feet. He missed the par-saving putt though. Stenson atoned for that mistake with a 6-foot birdie putt at the last to end two back.
"I gave myself lots of chances and rolled in a nice one there at the last. It was important for me to get up and down at the last to stay within two," Stenson said. "There are heaps of low scores out there. You've got to keep on making birdies if you want anything to do with this tournament."
NOTES: The first seven groups started before the weather delay hit, then their scores were wiped out and the round started fresh at 12:15 p.m. (ET) ... Garcia has won just three of the previous 10 times in which he owned at least a share of the 54-hole lead ... DeLeat tied his career low round with his 62 ... Tiger Woods tripped to a 1-over 73, which was his seventh above par score in 35 rounds in this tournament.
