Graeme McDowell finished with three successive bogeys and looked likely to join Seamus Power in missing the cut the rain-delayed Puerto Rico Open.
McDowell is a shot outside the projected three-under-par cut mark after a second successive 71.
But he will be disappointed with his finish having birdied the second, eagled the par-five fourth and then birdied the short sixth to get to five-under-par for the tournament.
When he followed a bogey at the 11th with a birdie at the 12th, there was still time to make a move into the top 20 at Coco Beach Golf & Country Club.
A two-hour rain delay did not help and McDowell finished poorly instead and now looks like joining Power and pal Ian Poulter (69-73) on the plane home.
Poulter is running out of time to keep full status under his major medical extension from a foot injury last year.
He has five starts remaining to earn 117 FedExCup points or $177,729.
Power opened with a bogey-free, three-under 69 but added a four-over 76 on Friday, going out in 35 but coming home in five-over 41 to finish on one-over par.
Bryson DeChambeau (65) shared the lead with D.A. Points and Bill Lunde in the rain-delayed event on 11-under-par when the second round was suspended by darkness.
