MARANA, Ariz. - Ian Poulter made short work of Sergio Garcia, then retreated to his room at the Ritz-Carlton and started posting on Twitter as he waited to find out who his opponent would be in the final of the Match Play Championship.

Paul Casey and Camilo Villegas are making him wait longer than he imagined.

They exchanged a series of great shots and clutch putts through 23 holes Saturday until twilight in the high desert made it too dark to continue. Casey and Villegas were to return Sunday morning to continue the longest match of the week at Dove Mountain.

“who is going to finish this match off, i want to get into a hot bath, come on guys someone hole a put please,” said one of Poulter’s tweet.

The hot bath couldn’t wait. Before long, Poulter was getting a massage.

Poulter had finished nearly three hours earlier after equaling the shortest match of the tournament with a 7-and-6 victory.

The final stroke of a long day belonged to Villegas. The 28-year-old Colombian had a 3-foot par putt at No. 14 to win the match, but in shocking fashion, he pushed it badly to the right and gave Casey an unlikely reprieve.

“I should have made that putt,” Villegas said.

Neither of them had gone the distance in any of their previous four matches. In the semifinals, they couldn’t finish.

“laying on the massage table having some treatment getting ready for tomorrow, cant believe they are still out there,” came another tweet from Poulter.

The match went overtime when Casey, who didn’t take his first lead until the 15th hole, missed an 8-foot par putt on the 18th hole. They gave each other 4-foot par putts on No. 10, and Villegas escaped trouble on the par-5 11th when he blasted out of a desert bush, hammered a fairway metal onto the green and halved the hole with par.

On the 22nd hole, No. 13, Villegas hit a tough bunker shot from 50 yards that stopped 2 feet from the hole for a conceded birdie, only for Casey to knock in a 6-foot birdie to extend the match.

They will resume the match at No. 10 in the morning.

“If I had to get up early, I wanted to be in the final. I didn’t want to be continuing a semifinal,” said Casey, who reached the championship match last year only to lose to Geoff Ogilvy. “One of us has to be in the final. And both of us want to be there.”

It was only the second time in the 12-year history of this tournament that a semifinal match went into overtime. The other time was in 2004, when Davis Love III defeated Darren Clarke.

Casey is trying to give this World Golf Championship its first All-England final.

Earlier in the day, Casey built an early lead and defeated British Open champion Stewart Cink, 5 and 4. It was the fourth time in as many matches that Casey had closed out his opponent by that score.

Cink’s loss meant no Americans reached the semifinals for the first time in tournament history.

The morning chill turned worse as gray clouds moved in, and rain began falling as the quarterfinals were ending. The rain came down so hard that play was halted for 10 minutes early in the semifinal matches.

The golf was as miserable as the weather.

Garcia took five shots to reach the first green before conceding the hole. Casey topped a tee shot so badly on the 209-yard third hole that it traveled barely 100 yards and didn’t even reach the water hazard.

“It was just nice that rain did back off so we could actually play some sensible golf,” Poulter said. “It certainly wasn’t enjoyable. The golf would have been terrible to watch.”

Poulter had a blast when the weather improved, winning four straight holes to build a big lead, then effectively closing out the match with four straight birdies.

Poulter won seven holes in an eight-hole stretch, but it was the one he lost — to a par by Garcia — that caused some consternation.

Garcia was 75 feet away for birdie on No. 7, while Poulter went over the green and into the desert, his ball stuck behind a bush. He asked for relief from a television tower and was denied. Poulter protested that he was capable of hitting through the bush and over the tower, a shot he would only consider in match play.

Calling in the chief referee, he won his appeal. But when he realized that his free drop would be in a thicker bush, he opted not to take relief, then played away from the tower. Poulter made bogey, forcing Garcia to nervously knock in a 6-footer for par.

After the match, Garcia was asked if he felt Poulter should have played the shot he intended when asking for relief.

“Well, probably,” Garcia said. “That’s what I would have done after trying to get relief. But he did what he thought was right, and he’s the one who has to live with it, so he’ll be fine.”

That phrase — “he’s the one who has to live with it” — can suggest that Poulter did something wrong.

Poulter said he wasn’t put off and stood my his decision.

“It’s my prerogative,” he said. “Do I want to give Sergio the hole if it doesn’t come off? I want to see him putt, and I’ve got every right to see him putt.”

Poulter had a far more difficult time reaching the semifinals.

Thongchai Jaidee of Thailand, the No. 48 seed, had never trailed in 59 holes until Poulter won the 17th hole with a par to go 1 up. Poulter won on the 18th when Thongchai’s 15-foot birdie hung on the lip.

In the other quarterfinal matches, Garcia pulled away late over Oliver Wilson of England, 4 and 3; and Villegas built a 4-up lead at the turn and beat Retief Goosen, 4 and 3.
