DORAL, Fla. (AP) — The speculation at the start of the year was when Tiger Woods would win.

Now it’s when he can play again.

The sequence Sunday at Doral was troubling. Woods hobbled. He changed his shoes at the turn. He began lifting his left leg to try to flex his ankle. He limped. And after one last powerful swing that produced a 321-yard drive on the 12th hole, he winced and walked over to Webb Simpson to tell him he was done for the day.

“He just shook my hand and said, ‘I’ve got to go in.’ You could tell he was hurting,” Simpson said.

To what degree, only Woods knows. And when he does, it becomes a matter of how much information he will share.

He started Monday night with Twitter, limited to only 140 characters: “Got good news from doc tonight. Only mild strain of left Achilles. Can resume hitting balls late in week and hopeful for next week.”

Woods said his left Achilles tendon felt tight as he warmed up on the practice range before the final round of the Cadillac Championship, and it got worse from there. Still unanswered is how the tendon flared up without notice. Perhaps the more important question is whether — or when — it might happen again.

Remember, it’s the same Achilles tendon that caused him to miss two majors last year.

The Masters starts in 24 days.

This is the one major he has never missed. Augusta National is where so many expected him to resume pursuit of the 18 majors won by Jack Nicklaus, the only record that really ever mattered to Woods, who has been stuck on 14 since the 2008 U.S. Open.

Beyond that benchmark, however, comes another question that no longer seems as ludicrous as the injuries keep piling up.

Will Woods ever win again?

Until Sunday, he was making big strides in that direction. Woods ended last year with an unofficial win in his Chevron World Challenge against an 18-man field, with birdies on the last two holes. He started this year tied for the 54-hole lead in Abu Dhabi and finished two shots behind Robert Rock. Only a week ago, he shot his lowest final round ever — a 62 that was punctuated with a 5-iron over the water to 8 feet for an eagle that put a brief scare into Rory McIlroy.

But he’s not winning.

Worse yet, he’s not giving himself as many chances as he once did.

Woods has played only 32 tournaments since returning, at the 2010 Masters, from the scandal in his personal life. He has missed the cut twice. He has withdrawn three times. And he has 21 finishes out of the top 10 — that’s as many times out of the top 10 from the 2004 U.S. Open to his last official win at the 2009 Australian Masters.

Woods has not played a complete season since 2009, and that one didn’t get started until the Match Play Championship when he returned from reconstructive knee surgery.

He’s not the same player he was. That much is clear.

He might not ever be.

Woods turned 36 at the end of last year, but he’s an old 36.

Woods already has had four surgeries on his left knee dating to when he was at Stanford. He first mentioned his left Achilles after the Masters last year, saying he injured it in the third round at Augusta while trying to play a shot from an awkward stance under Eisenhower’s Tree on the 17th hole.

He tried to return too early at The Players Championship and quit after nine holes and 42 shots, then sat out for three months until he was convinced his left leg was strong as ever. That enabled him to work on his new swing, to resume physical training, to get stronger.

There was no indication of an Achilles problem until early in the final round. And that can only lead to speculation that perhaps his Achilles really is his Achilles, more than the knee.
