The biggest stories from day four in Austin

Only four players remain at the WGC – Dell Technologies Match Play after a thrilling day of knockout golf.

Here, we take a look at the three biggest stories from day four.

Springtime for Bubba

The snow has melted, the nights are getting lighter and Bubba Watson is finding form – Spring must be on the way.

Of Watson’s ten wins on the US PGA Tour, seven of them have come between January 30 and May 1, including his two Masters Tournament triumphs.

He is once again feeling the joys of Spring, taking his exhilarating style all the way to the last four in Texas with wins over Brian Harman and Kiradech Aphibarnrat on Saturday as he peaks at just the right time.

Watson will, however, be missing a flight out of the country tomorrow. After his quarter-final win, he said: “Well, my wife’s cell phone is off right now, and I’m supposed to be on a flight at 9am tomorrow to go out of the country on vacation. I’m going to have to tell her that we ain’t making it.”

Thomas looking out for number one 

Justin Thomas has swept all before him so far this week, winning all three of his Group 2 matches before seeing off Si Woo Kim and Kyle Stanley on Saturday.

And there is a big prize on offer if the American can carry on winning tomorrow.

Thomas needs to beat Watson in Sunday’s semi-final to take over from Dustin Johnson as World Number One – and if his performances so far this week are anything to go by, he has every chance.

He said: “I don’t care when it happens I just hope it happens and it happens for a while.

“But I’m just worried about trying to beat Bubba Watson tomorrow.”

Noren into the final four

The only thing that could stop Alex Noren from reaching the semi-finals at this event last year was Dustin Johnson as he powered to victory.

But nobody has even come close to halting the Swede’s progress this time.

Many would have expected Noren to face resistence against American Ryder Cup star Patrick Reed but he cruised to a 5 and 3 win to set up a quarter-final with Cameron Smith.

And despite struggling at times against the Australian, he emerged victorious and will battle it out with Kevin Kisner for a place in the final.
