"The season is pretty much over very soon," the 39-year-old added. "But the year's not.
"I still can do things overseas, our next (PGA Tour) season is starting up, I have my tournament down in the Bahamas. There's plenty of golf to be played globally. The season, it is what it is, but calendar year I still have a lot of golf left."
