Masters Tournament 2017: Mobile Updates for Friday Leaderboard Scores

The withdrawal of world No. 1 and pre-tournament favourite Dustin Johnson ahead of his opening round made for a dramatic start to the 2017 Masters on Thursday.

What then followed was a remarkable first day of action in which 40-year-old American Charley Hoffman defied tough conditions to post a spectacular round of 65 and take a four-shot lead. 

William McGirt carded the only other sub-70 round to place second on three-under after 18 holes, while former world No. 1 Lee Westwood finished the day alone in third after a round of 70.

None of the world's top-10 ranked players were able to shoot under par on Thursday, and the likes of Rory McIlroy, Jordan Spieth and Jason Day have some catching up to do during Friday's play.

McIlroy is the best placed of the hot pre-tournament favourites after he battled back from a frustrating front nine to card a respectable level-par round on Thursday.

He has the momentum with him having cancelled out bogeys on the first, third and eighth with a late flurry of birdies on 13, 15 and 16.

McIlroy admitted to being stunned by Hoffman's 65 given the conditions but said he was delighted with his round and believes he remains in contention, per Neil McLeman of The Mirror:

"

I thought if anyone broke 70 today that would be an unbelievable score and then to see what he did over the last six or seven holes was incredible golf.

I'm walking off there after my start ecstatic with a 72 and he is walking off with a 65, but as they say they don't give green jackets out on Thursdays and there is no winning post there.

I think I'm in a good position with three rounds to go and we will see how it goes.

"

As alluded to by McIlroy, a good opening score can end up meaning nothing come Sunday, but Hoffman's round was remarkable—he birdied seven of the final 11 holes—and he has made himself the man to beat.

The PGA Tour provided highlights of his round:

All eyes will be on the world No. 52 on Friday to see if he can repeat his first-round heroics.

Spieth knows how to go low around Augusta having tied for second in 2016 and 2014 and won his first green jacket in 2015.

His round of 75 on Thursday included a quadruple-bogey nine on the par-five 15th, without which he would have shot under par.

It is not the first time Spieth has endured a horror hole at Augusta. His seven at the par-three 12th in the final round last year ended his chances of back-to-back Masters wins as Danny Willet came from behind to claim the green jacket.

This year, though, Spieth has three more rounds, not six holes, to rectify his mistake, and he will be looking to shoot in the 60s to get back on track on Friday, and he is more than capable of such a feat.
