CARLSBAD, Calif. — The only drama during the last day of the Match Play Championship was in the consolation match.

There certainly wasn’t any in the championship round. Not the way David Toms wrapped up an incredible run at La Costa on Sunday.

Toms had Chris DiMarco whipped even before lunchtime.

Toms got so far ahead at one point that they almost didn’t have to make the turn onto the back nine of the 36-hole final. His mind began wandering toward what he would say at the trophy presentation, and he actually whacked himself on the head to stop the idle thoughts.

When he sank an 8-foot birdie on the 13th hole, he wrapped up a 6-and-5 victory that earned him $1.3 million. It was his 11th career PGA Tour victory, and first World Golf Championship title.

‘‘It just felt easy at times for me, I guess,’’ Toms said. ‘‘Not easy to beat my opponent, but the golf in front of me, as far as the shots and everything. I really felt comfortable.’’

Toms won a tournament that lacked a weekend buzz after top seeds Vijay Singh, Tiger Woods and Phil Mickelson were eliminated Friday.

The highest-seeded player still left playing on the weekend was Retief Goosen, who lost his semifinal match Saturday to DiMarco, but came back Sunday and beat Ian Poulter in 20 holes in the consolation match.

Toms merely delivered the most dominant performance in the seven-year history of this fickle tournament, winning eight out of nine holes to put away DiMarco before lunch, then pouring it on in the afternoon.

Toms was 9 up at one point and had a chance to end the match on the 27th hole. Tournament officials trailed Toms over the final four holes with the Walter Hagen Trophy and a podium in the cart, waiting to set up the trophy presentation when the drubbing was over.

‘‘That’s the worst beating I’ve taken for sure,’’ DiMarco said.

DiMarco played some of his best golf when it no longer mattered. He saved par from thick rough behind the ninth green, then made three straight birdies.

It was his 11th career victory on the PGA Tour and moved Toms up to No. 9 in the world ranking.

‘‘I’ve won a few tournaments along the way, but I never felt this at ease on the golf course,’’ Toms said. ‘‘Not that it was easy. I just felt I could hit the shot no matter what it was. I have no idea how to explain it.’’

He never gave DiMarco any hope.

‘‘They got a good champion,’’ said DiMarco, whose $750,000 runner-up check was the largest of his career.

The match was even through nine holes until Toms went on another tear, making birdie on five of the next six holes to take a 6-up lead after the morning round, the largest ever.

By then, the sparse gallery at La Costa knew this was over. At times, it looked as though DiMarco knew, too.

After winning on the 18th hole in the first two rounds, Toms simply had no match the rest of the week — not Mickelson, not Scott, not anyone.

He was awesome against Poulter in the semifinal, going birdie-eagle-eagle to seize control and hitting every approach over his final eight holes to within 12 feet.

DiMarco saw highlights Saturday night, then saw firsthand just how good Toms was playing.

‘‘I think those are probably two of the best back-to-back rounds you can see,’’ DiMarco said.

Toms felt exactly how Woods has during some of his big wins.

‘‘When Tiger played his best golf and the way he made birdies and dominated fields and made it look easy at times, I guess maybe that’s what it feels like,’’ Toms said. ‘‘I could certainly get used to that.’’
