Quicken Loans National 2016: Saturday Leaderboard Scores and Highlights

Just 18 holes remain at the Quicken Loans National at Congressional Country Club in Bethesda, Maryland, and Billy Hurley III holds a two-stroke lead after shooting a four-under 67 on Saturday to sink to 15 under overall for the tournament.

He's opened up a bit of a cushion at the top of the leaderboard, as only two golfers are within three strokes of him.

Here's a look at the leaderboard:

Hurley began the day tied for first with rookie debutant Jon Rahm at 11 under. While Rahm didn't have a bad day, going one under, Hurley took advantage of the scoring conditions at Congressional and put together another clean round.

It wasn't a busy day for Hurley, but three birdies on the front nine and one more on the back were more than enough to ensure that he stayed atop the leaderboard.

He was again accurate in the longer aspects of the game, posting a 71.43 percent driving success rate while hitting 77.78 percent of his greens in regulation Saturday.

But the biggest day belonged to Ernie Els, who shot a six-under 65 to sink to 13 under for the tournament. 

His day began unassumingly enough, with five straight pars, but then Els reeled off three straight birdies on Nos. 6, 7 and 8.

Tied for third at 10 under, Els catapulted into second with an eagle at No. 12, which he holed out from 160 yards away, as the PGA Tour showed:

He added a birdie on No. 14 to put the icing on a stellar round and put himself in position to break a four-year drought. The last time he has won an event on tour was in 2012, when he won the British Open.

Els is one stroke ahead of Rahm, who despite a tough day is still in the conversation. 

Four birdies on the front nine were canceled by bogeys on Nos. 3, 4, 11 and 13. Rahm's final bogey of the day began with a shank on his first shot, via the PGA Tour:

His day could have been worse had it not been for his superior putting, as he gained 2.393 strokes on the day. But if he wants to work his way back up to first, he will need to hit more than 68.52 percent of his greens in regulation, which is no more than the field average this week.

Hurley's advantage isn't secure, given the way golfers have been able to play an aggressive style and lower their scores. While Hurley doesn't have to be aggressive to close the tournament out, he will have to be just as accurate as he's been over the first three days. 

With a seasoned veteran like Els hot on his trail, there is little disputing that Hurley's lead will be under pressure Sunday.
