'It was just one of those weeks where everything was good from tee to green,' Ochoa told the cheering crowd, some waving Mexican flags, as she stood on the 18th green and struggled to lift the outsized two-handled silver mug trophy.
'It's like a soccer trophy. I like it.'
Creamer finished with a 68.
'I gave myself a ton of chances out there and that's all you can ask for on Sunday. I tried my hardest,' Creamer said.
Shi Hyun Ahn (66) was third at 10 under, and Brittany Lang (67) and Laura Diaz (72) followed at 9 under.
Alena Sharp was the top Canadian, closing with a 69 to tie for 10th -- the Hamilton, Ontario, player's highest tour finish -- at 6 under.
'This is definitely going to give me more confidence. I know I can be one of the best players out here,' Sharp said. 'I hit some great shots today. I had a couple of tap-in birdies and that always helps.'
U.S. Women's Open champion Cristie Kerr, the winner last year at London Hunt in Ontario, shot a 75 to tie for 50th at 1 over.
'You're not going to defend any golf tournament playing like this,' Kerr said. 'I didn't hit it good today and my putting woes continued. It would have been funny if I just chucked my putter in the lake after the round because I'm not using it anymore.'
