MARANA, Ariz. -- In 11 attempts, Lee Westwood has never advanced beyond the second round of the World Golf Championships-Accenture Match Play Championship. As he said Tuesday, "It's not quite happened for me in this tournament."

Of course, it's not like he's been blown out ... well, at least not in recent years. Since losing to Davis Love III 7 and 6 in 2005, Westwood has lost six matches that went at least 17 holes. In fact, three of those losses required extra holes, including a 26-hole match to Scott Verplank in 2006 and a 23-hole match to Stewart Cink in 2009.

"I can't put my finger on it," Westwood said when asked about his struggles in this event. "I've played well in individual rounds. I had bad luck a couple of times."

The Englishman enters this week as the No. 1 seed in the Sam Snead bracket, but his first-round match will not be easy. He'll face big-hitting Belgian Nicolas Colsaerts on Wednesday.

Colsaerts reached the semifinals last year at the Volvo World Match Play Championships. Westwood has seen Colsaerts' match-play ability up close. At the Vivendi Seve Trophy last September, Westwood and teammate David Horsey beat Colsaerts and teammate Raphael Jacquelin 4 and 3 in Saturday foursomes.

Colsaerts is making his first appearance in the Accenture Match Play, but Westwood doesn't think it will take long for the Belgian to feel comfortable at Dove Mountain.

"He's got a game suited to this course and this format," Westwood said, "so it will be a tough match."
