By reaching the semifinals, Tanihara will move into the top 50 in the world ranking next week and qualify for the Masters. Ross Fisher also will get into the top 50 and return to the Masters by reaching the quarterfinals.

Phil Mickelson rallied from 3 down at the turn to win the 10th and 12th holes. But he missed two putts to square the match, Haas made a 4-foot birdie on the 15th hole to go 2 up and close him out on the 17th.

(Golf

Channel); with two late birdies in the morning fourth round, and then he beat Ross Fisher, 4 and 2, to reach the semifinals. Johnson has looked unstoppable all month. Now he’s two victories away from becoming the first player to sweep the four World Golf Championships.

None of Johnson’s five matches has gone beyond the 16th hole. In the fourth round, he beat Zach Johnson, 5 and 4. Noren is the only player to really make him sweat, and that was Johnson’s doing.

Johnson went 3 up at the turn, and then it was gone. He three-putted from 30 feet to lose the 10th hole. His tee shot on the par-3 11th hit the rocks and went into the water. And then he had to settle for par after leaving himself in an awkward spot, only to watch Noren hole a 40-footer to tie the match.

Johnson made a 10-foot birdie putt on the 13th — Noren missed from 8 feet — and then began to pull away with another 10-foot birdie on the 15th.

Also: Stroud leads in Puerto Rico

RIO GRANDE, PUERTO RICO >> Chris Stroud has gone 276 tournaments over the better part of a decade trying to win on the PGA Tour. A birdie on the final hole Saturday in the Puerto Rico Open gave him his first 54-hole lead, and he hopes his experience will keep him calm.

Looking over his shoulder could make that very difficult. Stroud kept a clean card at Coco Beach Golf and Country Club for a 5-under 67, giving him a one-shot lead over Bill Lunde and D.A. Points. What makes the final round more challenging is 10 players were within three shots. CARLSBAD, CALIF. >> Mirim Lee shot a 5-under 67 in the third round of the Kia Classic to go to 13-under and take a one shot lead over Mi Jung Hur, who made a 67-foot putt on No. 18 to card a 66.
