'It's a beautiful day,' said Miyazato, the 22-year-old Japanese star seeded 12th in the 64-player event. 'I just had fun. It was a great match.'
Miyazato, a 14-time champion on the Japanese tour, but winless in 42 career LPGA Tour starts, faced No. 22 Seon Hwa Lee (22) in the afternoon final on the hilly, tree-lined Wykagyl Country Club course.
'I need to make birdies,' Miyazato said.
Lee beat No. 10 Mi Hyun Kim 2-up in an all-South Korean semifinal.
'Ai's a really good player,' Lee said. 'I'm just going to try to enjoy it.'
Trying to become the 10th Japanese player to win on the LPGA Tour and the first since Akiko Fukushima in 1999, Miyazato took a 2-up lead with a par on the par-4 11th. After Hjorth cut the lead in half with a birdie on the par-4 12th, Miyazato took the par-4 14th and par-5 16th with pars to close out the tall Swede.
Miyazato got off to fast start, winning the par-4 third and fifth with pars to take a 2-up lead. Hjorth won the par-3 seventh with a par.
After opening victories over No. 53 Becky Morgan (5 and 4) and No. 21 Sherri Steinhauer (4 and 2), Miyazato beat No. 37 Christina Kim (2 and 1) and No. 61 Amy Hung (1-up) on Saturday to reach the semifinals.
The 21-year-old Lee parred the par-4 fifth to pull even with Kim, then moved ahead with a birdie on the par-5 ninth. Lee won the 11th with a par and the 12th with a birdie to take a 3-up lead. After Kim won the par-3 13th and par-5 16th with pars, Lee ended the match with a birdie on the par-5 18th.
'I putted really well on the back nine,' Lee said.
Lee won the final ShopRite LPGA Classic last year in New Jersey for her lone LPGA Tour title, closing with a 63, and was the rookie of the year. She also won a Futures Tour event two years ago in Albany.
The young South Korean reached the quarterfinals with a 3-and-2 victory Saturday over No. 35 Lindsey Wright after beating No. 43 Diana D'Alessio (1-up), No. 54 Janice Moodie (5 and 4) and No. 27 Laura Davies (2 and 1) in the first three rounds.
The champion will receive $500,000 from the $2 million purse. The runner-up will get $300,000, third place is worth $200,000 and fourth $150,000.
