Justin Rose wins as Dustin Johnson collapses

There's no snugger place in the world than the clubhouse when you know you've posted a target after a stunning final day, and you're watching the overnight leaders fall apart all over the place.

Queue Justin Rose, whose final round 67 was enough  to earn him a two shot victory at the World Golf Championship HSBC in Shanghai.

The Olympic champion overturned a whopping eight-stroke deficit at Sheshan International Golf Club for a most welcome first victory of 2017.

This was Rosey the night before, summing up his 'chances' for the final day. And, drinking a cup of Rosey...

DJ had a six shot lead going into the final round, but missed out on the chance of becoming the first player to win three World Golf Championship titles in a calendar year after crashing to a bogey-laden 77.

The world No 1 ended up in a share of second place at -12 alongside Henrik Stenson and Brooks Koepka.

It started badly for DJ as he bogeyed his first hole, and then it got worse as he lost his ball on the next. Koepka was closing in at this stage but quickly declared his own problems with back to back bogeys at 3 and 4. 

DJ gave the chasing pack more encouragement when he dropped a shot at the 12th, allowing Koepka to close the gap to just one shot with a birdie at the par-five 13th.

Far down the course, Rose was doing his best work at this stage, birdying three holes from the 11th to 14th, getting to just twp shots from the lead which was then held by Henrik Stenson.  

When DJ bogeyed the 15th, where Koepka also obligingly racked up a double-bogey, Rose was in sperlative form, bagging birdies at the 16th and the 17th. Suddenly, he has aone shot lead.

A two-putt at the last set the clubhouse target for Rose, while Stenson and DJ's trials and tribulations on the back nine meant they both needed eagle at the last to force a play off. 

Stenson went left off the tee and was forced to lay up on the par-five, as Johnson found water with his approach to guarantee Rose his first victory since last year's Rio Olympics.

Good. Work. Fella.
