The 5-foot-7 Seo, whose nickname from her time on the KLPGA is Supermodel of the Fairways, was an elite swimmer from age 4-9. But she had to quit swimming due to chronic sinus infections. She then turned her focus to golf, picking up the sport in the fourth grade. Seo started competing on the KLPGA in 2006 but she didn't pick up her first win on the Tour until 2008.
On the KLPGA Tour, there is one-month break during the summer because of the rainy season. During that break in 2008, Seo trained with Jiyai Shin and has credited Shin with helping to improve the mental part of her game as she started winning on the KLPGA shortly after. Shin was in Seo's group for the third and final rounds of this U.S. Women's Open championship.
Now with a few players chasing her as they have a few holes remaining in their rounds, Seo will have to wait overnight to find out if she will become a Rolex First-Time winner at this U.S. Women's Open. Seo was asked if it will be difficult to sleep knowing that it's possible she could capture her first official win on the LPGA Tour and her first major championship on Monday.
"Nobody knows what's going to happen tomorrow," Seo said. "I think they're going to have no wind in the morning, so I will just pray and wait."
"I did my best and I did all my things, so even if I could not be winner, I don't mind," she said. "I just did my best, and that's all."
