Woods still a doubt for Augusta.
The 14-time major champion is struggling with a back injury and there are doubts about his participation at Augusta.
The tournament starts on April 10 and Woods was not ruling anything in or out when asked about his odds of playing.
He said: "For Augusta, it's still a little too soon (to know), to be honest with you.
"That's kind of the frustrating thing about this. I had a couple weeks off, was getting treatment and trying to get ready for Augusta.
"As of right now, it's still too soon. As I said, that's very frustrating."
BOXING: Amir Khan has pledged to return "better, more skilled and smarter" when he ends what will be a 13-month absence from the ring on Floyd Mayweather's undercard on May 3. Khan has not fought since a poor points win over Julio Diaz in Sheffield last April but will be back in action when he makes his welterweight debut against American Luis Collazo in Las Vegas.
The 27-year-old said: "Being out of the ring for so long has helped me work on a lot of different things that you usually wouldn't get the time to focus on.
"It has come at the right time for my move up in weight, and it is going to make a massive difference. You'll see a different fighter - better, more skilled, patient and smarter. I can't wait."
