Justin Thomas hit a remarkable shot to save par on the first hole of his final round at the WCG Bridgestone Invitational on Sunday.The 25-year-old American, who led going into the final round, found himself in the bunker after his tee shot and was faced with a series of trees between himself and the hole.He then pulled off an incredible shot, drawing the ball around the trees with it eventually settling just in front of the green.The former world No. 1 never looked back after this as he stormed to victory in Akron, Ohio, eventually finishing -1 for the round and 15 under for the tournament, four ahead of fellow American Kyle Stanley, and Thorbjørn Olesen and Dustin Johnson, who finished tied for third place on 10 under."I take a lot of pride in how I played today," Thomas told reporters."I was very nervous going in. With a three-shot lead I knew I needed to play well but I had a little bit of wiggle room.”The day took on special meaning for Thomas as his grandparents were in the crowd to see him win.His grandfather Paul Thomas played in the 1960 PGA Championship at Firestone.

"They don't get to come out very often any more. This is my first PGA Tour win with them here, so it's pretty cool."

Brits Rory McIlroy and Ian Poulter finished off the pace. McIlroy carded 73 on the final round to finish seven behind the winner, whilst Poulter finished on eight under having hit four bogeys in the first seven holes.

The win was the American’s ninth in total on the PGA Tour, and his third of the year. Only Dustin Johnson and Bubba Watson have won as many in 2018.

It sets Thomas up well going into the PGA Championship which begins on Thursday 9.
