Jason Day has moved into the WGC Match Play semi-finals for the second straight year with a win over Louis Oosthuizen in Arizona.

Jason Day says he’s had enough of the near misses and is determined to win the WGC Match Play Championship at Dove Mountain in Arizona.

The 26-year-old stormed into the semi-finals for the second straight year after taking out South African Louis Oosthuizen 2 and 1 in the quarter-finals, setting up a final-four showdown with American Rickie Fowler.

World No.11 Day, who would jump to a career high No.4 if he wins the trophy, knows his time is now if he is to clinch his first victory in the United States since 2010.

While Day won the individual section of the World Cup at Royal Melbourne last November, he hasn’t claimed a US PGA tour win since his only one at the Byron Nelson Championship almost four years ago.

Since then he has 26 top 10 finishes, including five runner-ups and three thirds with three of the seconds and a third coming in major championships.

He was also third in this event last year after losing his semi final to eventual champion Matt Kuchar.

A WGC win would be a huge boost to his resume – and his bank balance with a $US1.53 million ($A1.70 million) cheque – as they are thought of as the next rung below the majors.

“I am just sick and tired of finishing second, third and fourth and things like that,” Day told AAP.

“I am just determined to find a way to win.

“I think last year I was mentally and physically done by Sunday with how the weather was but this year is a different story.

“I feel a lot fitter. I’m ready to go out there and play 36 holes and I’m very excited to have a chance to win.

“Hopefully I can do a little better this year.”

Fowler, at just 25 years old, beat veteran American Jim Furyk 1-up and although they are friends, Day said he’ll be ready to rumble.

“Obviously he’s playing great golf right now because he’s through to the semis and it’s going to be interesting because we are really good mates,” Day said.

“But I’ll probably just get in my own little world again and just try to find a way to beat him.”

Fowler, at No.56 in the world, will be the underdog but isn’t fazed.

“It’s going to be fun tomorrow. He’s a great match play player, as well as just a great player in general,” Fowler said.

“Hopefully both of us can play well tomorrow and whoever makes more putts is going to win.”

South African veteran Ernie Els, 44, will play 23-year-old Frenchman Victor Dubuisson in the other semi.

Els beat Jordan Spieth 4 and 2 and Dubuisson beat Graeme McDowell 1-up.
