Sebastian Munoz shot a 2-under-par 68 on Saturday to maintain a two-stroke lead over Robert Streb after the third round of The Greenbrier Classic, keeping the PGA Tour rookie in position to become the tournament’s first wire-to-wire winner.

The 24-year-old Colombian was at 14-under 196 at Old White TPC in White Sulphur Springs, Va. Streb shot a 65.

Rookie Xander Schauffele and Jamie Lovemark were 11 under after 66s.

Davis Love III was at 10 under after a 68. At 53, he’s trying to become the oldest winner on the PGA Tour.

Kelly Kraft (67) and Russell Henley (68) also were 10 under.

While his birdie pace slowed to a trickle, Munoz overcame several miscues to stay atop the leaderboard. He saved par on the ninth hole after driving under a tree, regained the lead with a 26-foot birdie putt on the par-4 13th after driving into the rough, and added a 36-footer for birdie on the par-4 15th.

Streb, five strokes behind Munoz entering the day, birdied the 490-yard 11th and hit his 231-yard approach shot next to the flag and made eagle at the par-5 12th.

He'd like to do a little better than in 2015 at the tournament, when he lost in a four-man playoff won by Danny Lee.

That year, Streb broke his putter on the ninth hole in the final round when he tossed it at his bag next to the green. He made five birdie putts on the back nine with a 56-degree wedge. He was able to put a new putter in his bag for the playoff but was eliminated on the first extra without ever getting to use it.

Streb’s only top-10 finish this season was a tie for ninth at the Farmers Insurance Open. Munoz is still looking to crack the top 10. At the St. Jude Classic last month, Munoz was tied for the lead through 36 holes, but he played the final two rounds in 11 over and tied for 60th.

Love is among those trying to earn a spot in the British Open in two weeks. The leading four players not already exempt from the top 12 finishers will earn spots. Henley is the only player in the top 10 who has already qualified.

Age record-holder Sam Snead won the last of his eight titles at Greensboro in 1965 at 52 years, 10 months, 8 days. Love will try to break the mark at Snead’s former playground. Snead was the longtime head pro and pro emeritus at The Greenbrier resort. He died in 2002.

Kraft was tied for the lead with Munoz until making a double bogey at No. 13 and bogey at No. 14. Schauffele, another PGA Tour rookie, shot onto the leaderboard with a 60-foot eagle putt at No. 12.

LPGA — Katherine Kirk shot a 7-under 65 to open a four-stroke lead in the Thornberry Creek LPGA Classic in Oneida, Wis., and move into position to challenge the tour’s 72-hole record.

Coming off a career-best 63 on Friday, the 35-year-old Australian reached 20-under 196 in the first year event at Thornberry Creek — the Oneida Nation-owned resort near Green Bay.

The LPGA Tour record for 72 holes is 27 under, set by Annika Sorenstam in the 2001 Standard Register Ping in Phoenix and matched by Sei Young Kim last year in the Founders Cup, also in Phoenix. Sorenstam shot a record 59 in the second round.

Kirk played the first five holes in 1 over with a birdie on No. 1 and bogeys on Nos. 3 and 5. She rebounded with a birdied on No. 6, ran off four straight on Nos. 8-11, and added birdies on 13, 15, and 17. On the par-4 18th, she saved par with a 15-footer after finding the right fairway bunker and hitting her approach well left. Kirk won the last of her two tour titles in 2010.

South Africa’s Ashleigh Buhai was second after a 65.

European — Jan Rahm shot a second straight 5-under 67 at the Irish Open in Portstewart and moved into a share of the lead with Daniel Im in the third round.

On a day of good scoring over the links at Portstewart Golf Club, the 11th-ranked Rahm moved to 17 under overall after making four consecutive birdies from No. 11 and parring his way home.

Im, who was tied for the lead with Benjamin Hebert after the first two rounds, birdied five of his opening 14 holes and scrambled superbly at the end to shoot a 68 and stay alongside Rahm.

Hebert is a stroke behind after shooting 69.

Rahm, one of golf’s hottest talents, tied for 10th at the French Open last week in the Spaniard’s first appearance on the European Tour and looks in good shape to collect his second victory of 2017, after the Farmers Insurance Open at Torrey Pines on the PGA Tour in January.

Having turned professional only a little over a year ago, Rahm also finished third and second in his first two World Golf Championship events.

‘‘I've never led going into the final round so I am a little inexperienced in that sense,’’ said Rahm, who was persuaded to play the event by tournament host Rory McIlroy.

‘‘But I know what I did at Torrey Pines, both good and bad. Hopefully I won’t need two eagles in the last five holes again to win tomorrow.

‘‘I have exceeded my expectations massively. My putting and short game has never been my best ally on links courses, but this week has been the opposite.

“I'm not used to making this many putts and it feels great.’’
