MARANA, Ariz. — The stars are gone from the Match Play Championship. Still alive are Ian Poulter and Hunter Mahan, the best in match play over the last few years.

Poulter added to his reputation as one tough customer Saturday when he beat Steve Stricker with one big putt after another, raising his record in this fickle format to 19-3-2 over the last four years.

Mahan outlasted U.S. Open champion Webb Simpson in 18 holes, leaving him two wins away from joining Tiger Woods as the only repeat winners of this World Golf Championship.

Mahan hasn’t lost a match in two years, and even more impressive than his 11 straight wins is that he has gone 151 holes at Dove Mountain without trailing.

Poulter and Mahan meet Sunday morning in the semifinals.

Matt Kuchar had no trouble against Robert Garrigus, building a 4-up lead through 10 holes and hanging on for a 3-and-2 win to reach the quarterfinals for the third straight year.

He faces Jason Day of Australia, who won a tight match against Graeme McDowell in 18 holes.
