Becky Morgan finished joint 25th at the State Farm Classic as South Korea's Ji Young Oh claimed her first LPGA title following a sudden death play-off with Yani Tseng at Panther Creek Country Club in Illinois.
Morgan, the only British player to make the cut, closed with a 71 and finished in a tie for 25th on 10 under par.
Oh beat Tseng with a birdie at the first hole of their play-off but the Taiwanese woman, who won her first title at the McDonald's LPGA Championship, led by two shots going into the final round and was one ahead with one to play.
But she bogeyed the 18th for a disappointing 72 and finished tied on 18-under par 270 with Oh, who made her move with a three-under 69.
In the play-off, Ji clinched the Ј125,000 prize when she hit from the rough to tap-in range for a birdie three at the par four 18th.
South Korea's Na Yeon Choi finished in third place on 17 under after a 68, and China's rookie, Shanshan Feng, had a best of day 63 to record her second successive tie for fourth place on 16 under alongside American Stacy Prammanasudh (69) and South Korea's Hee Won Han (71).
The tournament was rather overshadowed by Michelle Wie's disqualification yesterday - the 18-year-old thought she was in second place after a third-round 66, but was then disqualified for failing to sign her scorecard when she was in the recorder's tent on Friday.
She did eventually sign it after a volunteer ran after her - but that was too late, and the infringement only came to light after she had teed off on in the third round.
But Ji was a worthy winner, with a six birdie final round and she will now head to Europe for this week's Evian Masters in France and next week's Ricoh Women's British Open at Sunningdale.
Wie, for the first time since 2005, will be missing from both European tournaments.
Canada number one Alena Sharp had gone into the final day tied for 15th, but she could only manage a one-over-par 73 and dropped to joint 34th on nine under par.
The 27-year-old bogeyed the first and 14th before finally making a solitary birdie at the 18th.
Lorie Kane, the second Canadian to make the cut, closed with a 70, but it still left her outside the top 50 on five under par.
