Rory McIlroy will begin the final round of the Abu Dhabi HSBC Championship one shot behind co-leaders Thomas Pieters and Ross Fisher after producing a sensational 65 on Saturday.

Playing in his first event since calling an early end to his injury-plagued and winless season in October last year, four-time major champion McIlroy came into the third round three shots behind Ryder Cup partner Pieters after following up Thursday's 69 with a sparkling 66 on Friday.

And the Northern Irishman continued to make big strides up the leaderboard on day three, carding eight birdies and a solitary bogey to get to 16-under par and close the gap to a single stroke.

After his round, McIlroy told Sky Sports Golf: "I putted really well and hit the ball very well. So all in all, it was another great round and another really good confidence builder -- not just for this week but for the rest of the season, as well."

McIlroy has an impressive record at Abu Dhabi Golf Club, with four second-placed finishes to his name and added that he would love to go one better this year.

"It would mean a lot. I've had a lot of close calls here, I think about six top threes or something like that. I've never won my first start back out. I was close last year in South Africa, Stormy [Graeme Storm] beat me in a playoff. I'm excited to get back on the horse and give myself another chance tomorrow."

After firing five birdies and no bogeys in his first 17 holes, Pieters produced a good par save at the last to remain at the summit and Fisher joined the Belgian on 17 under after closing his 7-under-par 65 with a birdie at the 18th.

Defending champion Tommy Fleetwood and fellow Englishman Matthew Fitzpatrick were in a tie for fourth place on 15 under.

Fitzpatrick produced the lowest round of the day, carding 10 birdies and one bogey in his superb 63.
