SHEBOYGEN, Wis. — Tiger Woods is perhaps one day away from completing the worst season of his professional career.

A 75 on Thursday during the opening round of the PGA Championship at Whistling Straits leaves him fighting to make the cut on Friday and puts him in danger of missing three consecutive cuts in major championships.

A poor putting day also left Woods looking at the possibility that his 2014-15 season will end with no top-10 finishes in just 11 starts. Next week’s Wyndham Championship is the last regular-season event on the PGA Tour, and Woods has not qualified for the FedEx Cup playoffs.

Woods is tied for 86th after the first round of the PGA Championship; the top 70 and ties advance for the final 36 holes.

“Season or year? Because the season is pretty much over very soon,” Woods said. “But the year’s not. I still can do things overseas . . . I have my tournament down in the Bahamas [the Hero World Challenge]. There’s plenty of golf to be played globally. So the season . . . is what it is, but [in the] calendar year, I still have a lot of golf left.”

Woods is 186th in the FedEx Cup standings and needs to be among the top 125 after next week’s Wyndham Championship in Greensboro, North Carolina. He had hinted two weeks ago that he might consider adding the event if he could qualify for the playoffs, but a missed cut this week would mean he’d all but have to win in Greensboro.

The deadline for committing to the tournament is Friday after play concludes.

Woods is looking at missing the FedEx Cup playoffs for the third time in five years. He also failed to qualify in 2011 and 2014.

Where he plays next is unclear, although it is likely that his next event would be the Frys.com Open, which runs Oct. 15-18. That is the 2015-16 season opener. Woods might also consider playing overseas, and he also has his Hero World Challenge event in early December.

“If I play well, I play well and I’ll play more events,” Woods said Tuesday. “If I don’t, then I have more time to practice and get ready for the following events, for the next season and obviously some of the things I do on a global level.”
