Tiger Woods has gone more than two years without winning a major tournament and has lost his No. 1 ranking.

ST ANDREWS, Scotland - Vijay Singh has a theory about what ails Tiger Woods’ game: He hasn’t adapted his swing to the changes in his body.

Singh overtook Woods last month as the top-ranked golfer. Ernie Els moved into second place, dropping Woods to No. 3.

“I think his body and his swing do not match like they did some four or five years ago,” Singh said Wednesday on the eve of the Dunhill Links Championship. “So he has to adjust that. I’m sure that once he figures that out, he’ll be OK.”

“When Tiger first came on the scene, he was extremely strong,” Singh added. “I’m not saying he’s not strong now, but you do slow down a bit. So the golf swing has to match your body’s ability. You know, I have adjusted accordingly and for the better and I don’t think Tiger has done that. I don’t think he has progressed that way.”

Singh, 41, has won eight times on the PGA Tour this year, including his last three events. He has won $9.46 million, topping Woods’ record of $9.2 million set in 2000.

Woods, 28, hasn’t won a stroke play event since last year’s Amex Championship, and his only victory this year was in the World Golf Match Play Championship. He got married Tuesday in Barbados to longtime Swedish girlfriend Elin Nordegren.
