The world's No. 1 golfer stands at 4-under-par through 16 holes of his second round, two strokes off the projected cut line of minus-6. He is in danger of not making the cut for only the third time in his career.
Woods, who also missed the cut at the Byron Nelson Classic in May to snap a record-long streak of 142 consecutive cuts made, collected six birdies in his second round but also posted a triple bogey, a double bogey and one more bogey to finish 16 holes Friday at even-par.
The 46-time PGA Tour winner will likely need birdies on his final two holes to make the cut. But he will also need help at the par-4 17th, where his tee shot landed under a tree before the horn sounded ahead of the bad weather at around 5:00 p.m. local time.
Woods' struggles on Friday came at the Walt Disney World Resort's Magnolia Course -- the event is using two courses for the first two rounds -- but another top player also sputtered.
World No. 2 Vijay Singh will likely have a rare weekend off after he managed just a 1-under 71 at the Palm Course to finish two rounds at 4-under-par 140.
Singh has finished worse than 13th just once in his last 11 starts since missing the cut at the Memorial during the first week of June. Those 11 starts included eight top-10 placements and a victory at the Buick Open.
The prospect of Woods and Singh not making the cut stole the focus from players who scored -- or are scoring -- well during the first two rounds of a tournament which normally yields plenty of low scores.
Clubhouse leader Tom Pernice Jr. fired a 10-under 62 on Friday to reach 15- under-par 129 for the tournament, which is good enough for a one-stroke lead over Geoff Ogilvy, who is in the clubhouse at minus-14 after a 6-under 66 in his second round.
'I made some putts today. To shoot a 62 you obviously have to,' said Pernice, who collected 10 birdies in his bogey-free round while playing alongside Singh at the Palm Course.
'I didn't know how many under par I was, to be honest with you,' Pernice claimed. 'I knew it was going well...I was just playing golf.'
Carl Pettersson is tied with Pernice at 15 under through 15 holes in his second round. He will have an opportunity to pass the clubhouse leader when the second round resumes at 7:45 a.m. (ET).
Brandt Jobe equaled Pernice's 62 at the Palm Course and is two strokes off his pace at 13-under-par 131 through two rounds. Kent Jones is also at minus-13, but he has two holes to complete in his second round.
