Australia's Jason Day is certain of achieving a career-high world ranking after moving into the final of the £5.4million WGC-Accenture Match Play Championship on Sunday.

Day beat American Rickie Fowler 3&2 at Dove Mountain and will climb to sixth in the rankings if he loses this evening's final, or fourth with a victory.

The 26-year-old looked to be cruising to victory when he led by three holes with seven to play, but lost the next two to give Fowler hope of mounting a successful comeback.

However, Fowler then bogeyed the 15th after chipping across the green and into a drainage ditch and the match came to an anti-climactic end as the American three-putted the 16th from six feet.

"I knew Jason was going to be tough," Fowler told Sky Sports. "He made quite a few good putts, he didn't give me a whole lot. He missed a par putt on 12 but other than that he played solid all day.

"On 15 I was in a tough position, I couldn't really make anything of it and 16 was a complete mis-read. Jason played well and he's going to be tough to beat this afternoon."

Day added: "I felt like I had a really good chance of having a shot of winning this week and I am really looking forward to it. I played some nice golf today so hopefully I can keep it going in the final."

Day will face either Ernie Els or Victor Dubuisson in the final, with their semi-final all-square with two to play.
