Silvis: Brian Harman, who has been knocking at the door with five top-10 finishes this year, takes a one-stroke lead into the final round of the PGA Tour’s John Deere Classic.

The American shot a six-under par 65 in Saturday’s third round to grab a one-stroke lead in the $4.7 million tournament at the Deere Run course.

“I struck the ball beautifully today,” said the 27-year-old Harman, who rolled in two eagles on Saturday.

Harman sits at 17-under par 196 with three-time tournament champion and fellow American Steve Stricker in second on 197.

Harman seeks his first US PGA Tour victory but his winless status is not for lack of effort. In the 24 events he has played this season, his best finish is a share of third at the Northern Trust Open.

Stricker made eight birdies and just one bogey on his way to a seven-under 64.

Scott Brown flirted with a 59, but he settled for one of the best rounds of the year on tour with a 10-under 61 to stand third on 198, two shots adrift. Harman reached the green in two on the par-five second hole then drained a 29 foot putt for the first of his two eagles.

He made another eagle at 17 when he sunk 47-foot putt and that put him at seven-under. A bogey at No. 18 dropped Harman back to 17-under for the tournament.

“I hit 17 greens, I think I only missed a couple fairways,” he said. “It’s good to have the ball-striking under control. Just go play golf tomorrow and see what happens.”

Heading into the last few holes, Brown was gunning for the seventh 59 in Tour history and second at the John Deere Classic (Paul Goydos in 2010).

After a par at No. 16, Brown needed to eagle the par-five 17th and birdie the par-four 18th to shoot a 59. Defending champion Jordan Spieth shot a 67 Saturday and was six shots back on 202.

Meanwhile, Scot Marc Warren is eyeing a home triumph at the Scottish Open but will have to hold off the formidable challenge of the 2013 U.S. Open champion Justin Rose to prevail at Royal Aberdeen.

Warren hit a four-under par 67 on Saturday to reach 10-under for a total of 203 after the third round, good enough to hold first place in a tie with England’s Rose, who went one better with a five-under 66.

Warren last won on the European Tour in 2007, and gave up a three-shot lead with four holes to play at the Scottish Open in 2012, leaving him hungry to taste success in front of his home fans.

“It was a little bit scrappy towards the end there but I’m tied going into tomorrow and playing with a major champion. I’m in a great position, a very exciting position as well,” the 33-year-told the European Tour website.

“For us Scottish guys it doesn’t get much better than this. It’s our fifth major. I’ve been in this situation before, so once the gun goes I’ll be ready to do my job.
