Tiger Woods scrambled to a 74 while Ernie Els struggled to a three-over 75 as they completed their first rounds at the rain-hit Masters.
But neither player was able to even start their second rounds as heavy storms hit Augusta on Friday.
Woods resumed the day on two over on the fourth - his 13th - and, despite two birdies, added two more bogeys to his card.
Els, runner-up last year, remained at three under at the end of his round.
The South African double-bogeyed the fourth in his 75 but it was still far improved on his opening round in 2003 where he carded a 79 before eventually finishing sixth.
"I just couldn't get my yardages right," said Els. "My club selection was way off and it really cost me a lot of shots, probably four or five. I've got to work on that.
"It's such a fine line here. You try to be as aggressive as you can but I've probably been a bit silly.
"Seventy five is not a great score but it's not out of it. It could have been worse."
Of the other so-called "big four", world number one Vijay Singh ended on four under with a 68, picking up two shots on his way home after beginning the day on the 12th.
It was the Fijian's best opening round in 12 appearances at Augusta but it could have been even better after a five-foot birdie miss on the par-five 15th.
Defending champion Phil Mickelson signed for a first-round 70 after resuming on two under through 11 holes.
