When it was all over, Creamer had a wild round of 2-under-par 69, good enough to finish at 143, just three strokes out of the lead.
``Anything can happen out there, and I'm a prime example of it,'' she said.
The 18-year-old Californian, who won at Q-school last year to earn her tour card, has more than fit in in this, her first year as a pro. She has one win, one second and a pair of third-place finishes, including one at the LPGA Championship two weeks ago.
Nothing, however, compared to her round Friday. After starting with a bogey and a double, she looked to her caddie and said she was hitting the ball too well to be scoring so poorly.
Then, she proved it -- making six birdies and an eagle over the next nine holes -- the eagle came when she holed an 8-iron from 132 yards on No. 10 -- to get a share of the lead.
She couldn't enjoy it much, though, because of a wrenching stomach ache she got from gulping down some Gatorade.
``I was trying not to get sick on the golf course,'' she said. ``And it was great'' because the longest putt she faced during the stretch was only 10 feet.
A 45-minute rain delay gave her time to head to the bathroom and throw up, but it also stifled her momentum. She made three bogeys after the delay, then, in a fitting finish to the roller-coaster round, closed with a 20-foot putt to save par on No. 18.
``Just knowing that I made a lot of birdies and I am under par for my day was enough for me,'' she said, ``because now I know going into the weekend that I can do it.''
Laura Davies reached into her bag and pulled out the driver, drawing cheers from the gallery.
Though she said early in the week that there was no point in hitting driver on Cherry Hills' opening hole, Davies took a lash at the 313-yard par 4 anyway. With no hope of making the cut and little chance of cracking 80 for the second straight day, Davies figured it was worth a shot.
'Absolutely. I was hitting driver on every hole except 7,' Davies said.
Arnold Palmer made No. 1 famous by driving the green in 1960, using his birdie there to overcome a seven-shot deficit and win the U.S. Open. Davies' shot wasn't nearly as miraculous, landing about 70 yards short and left in the thick rough next to a tree. She punched through a small opening and landed on the green, but three-putted from 30 feet for bogey.
The hole typified Davies' two days at Cherry Hills.
She was 7 over in the first round Thursday when play was suspended due to weather, then closed it out Friday morning with a triple bogey, double bogey and bogey to shoot 13-over 84 -- her worst score in 66 U.S. Open rounds.
Davies opened the second round with a birdie on No. 10, then went back to making bogeys. She closed out the back 9 with a triple bogey on the par-4 18th to make the turn in 8-over 44, then had bogeys on three of her next four holes.
Davies has always been a fast player, but once things got really bad she played as if she needed to catch a flight. She hit her shots just seconds after playing partners Michelle Wie and Brittany Lincicome, and hit putts in succession as if they were playing by continuous putting rules.
And she kept hitting that driver.
'This afternoon was irrelevant. I needed to shoot 66 and that wasn't going to happen,' Davies said. 'I'd rather miss the cut by 10 than by one.'
As for the rest of the tournament, don't expect Davies to be tuning in.
'I don't care who wins,' she said. 'They run a great tournament, but I'm not part of it. I'll be out of here as fast as I can.'
Jill McGill grew up playing Cherry Hills and the local knowledge seemed to help her in the first round.
It didn't make much difference in the second.
After opening with a 1-over 72 on Thursday, McGill struggled with just about every aspect of her game for a 79 on Friday. She finished at 9-over par and when leader Nicole Perrot made a 4-foot putt to save par and finish at 2 under, McGill had missed the cut -- done for the weekend.
'It had nothing to do with knowing the golf course, it had to do with hitting bad shots,' she said. 'Whether you know a golf course or not, if you can't hit it straight you're going to score poorly.'
McGill's biggest problem was with the greens. After getting around in 27 putts in the first round, she needed 35 in the second, including three three-putts.
'My speed was way better yesterday and today I just didn't have a clue,' McGill said.
Among those joining McGill on the sidelines for the weekend were 2003 champion Hilary Lunke, Carin Koch, Kelli Kuehne, Beth Daniel and Davies.
On a day when scores climbed and big numbers dotted the scoreboard, Rachel Hetherington matched her best score in 24 rounds at the U.S. Open.
She started with a bogey on the par-4 first hole, but had four birdies on the front 9 to turn in even-par 35 and had three more on the back to shoot a 2-under 69. Hetherington, who also had a 69 in the second round of last year's Open, is at 1-over 143 through two rounds.
'Even when I was making bogeys, I actually hit good shots, just a little too long or a little too short,' she said. 'I am very happy with it.'
Cherry Hills' finishing hole was still giving players fits in the second round. The hole played 0.679 strokes above par and 21 players made double bogey or worse. That included Sophie Gustafson, who made a quintuple-bogey 9. Three players did, however, make birdie on the hole after a first round that didn't yield a single one. ... Brittany Lincicome had never played with Laura Davies before this week, but the two had crossed paths before. Lincicome was a standard bearer for Davies' group several years at JC Penney Classic in the Tampa Bay area.
