Graeme McDowell has risen one place to seventh in the world rankings after his win at the Volvo World Match Play Championship in Bulgaria.
The Portrush man saw off Thailand's Thongchai Jaidee, ranked 49th, to win what was his second title in his last three events.
And after winning one tournament synonymous with Wentworth, McDowell has now turned his attention to improving his record in the event still held at the European Tour's headquarters.
McDowell claimed his second victory in three tournaments yesterday, winning the Volvo World Match Play Championship at Thracian Cliffs in Bulgaria to add to his RBC Heritage win last month.
The top seed beat Thailand's Thongchai Jaidee 2&1 in a hard-fought final, taking the lead for the first time on the 14th and then making a birdie on the next as he became the first Irish winner of a tournament dating back to 1964.
Arnold Palmer won the inaugural event and the likes of Jack Nicklaus, Seve Ballesteros, Nick Faldo, Greg Norman and Ernie Els all triumphed at Wentworth before the tournament moved to Finca Cortesin in Spain in 2009.
McDowell believes the gamble of taking the 24-man event to Bulgaria paid off despite admitting the field needs to be stronger and that the spectacular course on the edge of the Black Sea has one or two "funky" holes.
And the former US Open champion will now be hoping to maintain his superb form at the BMW PGA Championship which gets under way at Wentworth on Thursday, an event in which he has missed the cut for the last two years and has just one top-15 finish in 10 attempts.
"We have been talking all week about how prestigious this event is. I can't say how excited I am to win it and add my name to that list of legends," McDowell said of his Match Play triumph, with the winner's cheque of €800,000 taking him top of the Race to Dubai.
"It was not quite the salubrious golf of this morning (when he was eight under in beating Branden Grace 3&2 in the semi-final). It was a little more tentative, there was a lot on the line.
"I played strongly coming in and I sensed Thongchai was a little fatigued. I really tried to feed off that and show him I was really up for it. He made his first mistake on the 14th and the 15th has been kind to me all week."
Slight headache this morning but definitely worth it! Thanks for all the messages and support this weekend. Felt good to win that! #volvo— Graeme McDowell (@Graeme_McDowell) May 20, 2013
