Ryan Armour and Webb Simpson finished Friday's second round of the 2017 Wyndham Championship at Sedgefield Country Club in Greensboro, North Carolina, tied for first place at 13-under.
Armour enjoyed the round of the day by firing a nine-under 61, while Simpson supplemented his excellent first round with a six-under 64 on Friday.
Here is a look at the top of the leaderboard through two rounds:
With the weekend left to play, 11 golfers are within four shots of the lead shared by Armour and Simpson.
Armour played nearly flawless golf Friday, as he ended his round with nine birdies and no bogeys on the scorecard.
He played the back nine first and birdied five holes on his opening nine before going on a dominant run near the end of the round.
Armour birdied four in a row from No. 5 through No. 8, concluding with this smooth putting stroke for birdie on the par-four eighth, courtesy of PGA Tour on Twitter:
While Armour has been a lower-end PGA Tour player for much of his career, he has started to come into his own in recent years.
In 2016, Armour won his first-ever Web.com Tour event, and now he is in search of his first PGA Tour triumph.
Per Justin Ray of GolfChannel.com, Armour is no stranger to being on a big stage against some of the world's best golfers:
Armour has momentum on his side after shooting a 61, but no player has been better at the Wyndham Championship in recent years than Simpson.
He was a model of consistency in his first two rounds with a 63 and 64 respectively, and aside from consecutive bogeys on No. 8 and No. 9, Simpson was locked in Friday.
It was apparent on the first hole of the day that Simpson was in for a great round, as he nailed a long, winding birdie putt:
Simpson won the Wyndham in 2011, and he almost always finds himself in the mix when he enters the tournament.
According to Ray, no golfer has come close to Simpson's penchant for carding low rounds in the Wyndham Championship over the past nine years:
Both Armour and Simpson have one of the world's truly elite golfers nipping at their heels in the form of Henrik Stenson.
The Swede is currently in third place at 12-under after having supplemented his 62 on Thursday with a second-round 66.
Stenson has had somewhat of a down year after breaking out with an Open Championship win in 2016, but his skill set is undeniable.
It was on full display Friday, especially on this amazing approach shot on the 17th hole:
Davis Love III is 53 years of age, but he is in a familiar spot at the Wyndham Championship in sixth place at 10-under.
Love shot a four-under 66 on Friday, and he is very much in the hunt for his fourth career Wyndham title.
Unlike Love, Matt Every failed to build upon a hot start Thursday, as he settled for a two-over 72 in the second round after shooting a first-round 61.
Every is six shots off the pace at seven-under, although a repeat of his first-round performance could get him back in the mix.
