Which player produced the round of the year in 2017? We take a look at some of the contenders…
Justin Thomas - Sony Open, opening round, 59 (-11)
A week on from winning the Tournament of Champions, Thomas became just the seventh player in PGA Tour history to shoot a sub-60 round to set him on his way to a wire-to-wire victory in Hawaii.
Beginning on the back nine, Thomas pitched in to eagle the 10th and responded to a blemish at the next by birdieing seven of his next eight holes around the turn to top the leaderboard.
A five-foot gain at the fourth was followed by a run of pars along the closing stretch, only for Thomas to roll in a 15-foot eagle at the par-five ninth - his final hole - to card a round of 59.
Adam Hadwin, CareerBuilder Challenge, third round, 59 (-13)
The Canadian joined the '59 club' with 13 birdies on a blemish-free scorecard seeing him take a one-shot lead into the final round at La Quinta.
Hadwin struck six consecutive birdies from the second and added another at the ninth to reach the turn in 29, before surging into contention with five gains in a row from the 11th.
A penultimate-hole birdie left Hadwin needing a three at the par-four last to post the first round of 14 under in PGA Tour history, only for him to miss the green and get up-and-down for par.
Sergio Garcia v Justin Rose, Masters, final round
Garcia snatched Masters victory in his 74th major appearance after edging past his Ryder Cup team-mate in a final-round tussle at Augusta.
The Spaniard saw a three-shot lead turn into a two-shot deficit with seven holes to play, only to birdie the 14th and eagle the 15th to take the contest to extra holes.
Both players missed birdie chances on the 72nd hole but Garcia made no mistake in sudden death, holing a 12-foot birdie to claim a maiden major title.
Alex Noren - BMW PGA Championship, final round, 62 (-10)
Noren equalled the Wentworth course record to come back from seven strokes behind to snatch an unlikely two-stroke victory, in the inaugural event of the European Tour's Rolex Series.
The Swede, out early on Sunday morning, birdied his first two holes and added gains at the fourth and seventh on his way to reaching the turn in 31.
A hat-trick of gains from the 12th were followed by a birdie-three at the 16th to give Noren a share of the lead, with a stunning approach and six-foot eagle at the last setting a clubhouse target which could not be beaten.
Justin Thomas, US Open third round, 63 (-9)
A final-hole eagle at Erin Hills saw Thomas set a new US Open record and equal the lowest round in major history.
Thomas opened with back-to-back birdies and cancelled out a blemish at the fourth with four gains over his next five holes.
The future major champion would bounce back from a bogey at the 10th to card three more birdies over the back nine, before holing an eight-footer at the last to shoot 63 and break the lowest round in relation to par ever seen in the tournament's history.
Tommy Fleetwood - Open de France, final round, 66 (-5)
Fleetwood secured a second win of the season and reached his highest-ever world ranking with a narrow one-shot victory at Le Golf National.
The Englishman almost aced the par-three second and made a two-putt birdie at the next, with further gains at the ninth, 13th and 14th briefly putting Fleetwood four clear.
As Peter Uihlein went on a back-nine birdie run to close the gap at the top of the leaderboard, Fleetwood holed a number of par-save putts to hold on to his blemish-free card and top spot.
Branden Grace - The Open, third round, 62 (-8)
Twenty-nine players in history had posted a 63 in a major, only for Grace to go one better at Royal Birkdale by becoming the first player to shoot a round of 62.
The South African took advantage of the par-70 layout by holing a 15-footer at the first and following back-to-back gains at the fourth with two more from the eighth, seeing him reach the turn in 29.
Grace drained a 35-footer at the 14th and holed another long birdie at the 16th, with a two-putt gain at the 17th and par at the last closing out a history-making round blemish-free.
Hideki Matsuyama, WGC-Bridgestone Invitational, final round, 61 (-9)
Matsuyama produced a ball-striking masterclass to equal the course record at Firestone and claim a sixth win in 20 worldwide starts.
The Japanese star was two off the lead heading in to the final round but surged up the leaderboard with an eagle-three at the second and three further birdies on his way to a front-nine 30.
A birdie-three at the 13th was followed by gains over his last three holes to complete a bogey-free 61, giving Matsuyama a five-stroke victory with a winning score of 16 under par.
Paul Dunne - British Masters, final round, 61 (-9)
The Irishman held off the challenge of world No 6 Rory McIlroy by firing a blemish-free 61 to claim his maiden European Tour title at Close House.
Dunne pulled level with overnight leader Robert Karlsson with a pitch-in birdie at the first and raced clear by following back-to-back gains from the fourth with an eagle-three at the sixth.
He capitalised on a lucky bounce off a sprinkler head to birdie the 11th and posted further gains at the 13th and 17th, before sealing victory with a chip-in from the rough at the last.
Ross Fisher - Alfred Dunhill Links Championship, final round, 61 (-11)
Fisher narrowly missed out on posting the first "59 round" in European Tour history on his way to setting a course record at St. Andrews.
The Englishman struck 11 birdies in a bogey-free display to finish runner-up in the event, with seven gains in a seven-hole stretch from the second lifting him up the leaderboard.
Four more birdies from the 12th left Fisher requiring an eagle at the driveable par-four last for a sub-60 round, but three-putted from just off the green for a closing par.
