Granada lost to Creamer in last year's quarterfinal at Brooklawn Country Club, but Friday was Granada's revenge.
'It feels good,' said Granada. 'I've hardly thought about it. I'll sure think about it tonight. It was so hard. Every shot counted, every putt counted. It was hard to breathe.'
Granada blew a 2-footer on the first hole to fall 1-down, the first time she has trailed in a match this week. Granada won the second to square the match, then took the eighth and ninth holes with pars to make the turn 2-up.
'The front nine I really didn't think I made her have to play golf,' said Creamer, who was a member of the victorious United States Curtis Cup team this year.
Creamer drew even with a birdie win at the 11th and a Granada bogey at No. 12. They halved the next four holes until Granada won the 16th to go 1-up.
The 17th proved critical as Granada was in for par. She almost conceded Creamer's 2-footer to win the hole, but instead Creamer rimmed the putt out of the hole to remain 1-down.
Once Creamer missed a 20-footer at the 18th, she conceded the match to Granada.
'All I could think about on 18 is 'You idiot. How could you miss that?,'', said Creamer. 'I never did shrug it off. I feel I should have won.'
Park won three holes in a row from the second, but Lu cut the margin to 2-down at the turn. They traded halves until the 15th when Lu three-putted for a bogey.
Lu failed to get on in two at the par-4 16th, while Park was 15 feet from the hole with her drive. Lu conceded and Park was in the final against Granada.
'I'm a little disappointed,' said Lu. 'Jane is a really good player and I didn't expect to win, but I was hoping to play better. But I played many days of good golf here this week and even though today I didn't do as well, I'm happy to have advanced to the semifinals.'
Park, the 2003 U.S. Women's Amateur runner-up, has seen her game improve all week, in anticipation of Saturday's final.
'I was kind of struggling with my game before I came here, but as the week progressed my game got more tidy,' Park said. 'I just told myself, 'If you just keep the ball in play, make the right club choice and have good course management, you'll be fine,' and I did that this whole week.'
