(CNN) -- Michelle Wie's long wait for her first LPGA Tour title is finally over after the Korean-American secured a two-shot triumph at the Lorena Ochoa Invitational tournament in Guadalajara, Mexico.
The 20-year-old, who turned professional at a precocious 16, fired a three-under- par 69 to finish ahead of Paula Creamer.
Wie finished with a flourish, blasting out of a greenside bunker to six inches at 18 and tapping in for birdie.
"It's definitely off by my back now," Wie, who experienced at an early age the pressure of massive expectations, told reporters.
"I think that hopefully life will be a lot better, but I still have a lot of work to do."
Wie won with a 13-under par total of 275 after starting the day tied for the lead with compatriot Cristie Kerr.
Creamer closed with a 70 to take second on 277. Morgan Pressel (67), Korean Jiyai Shin (71) and Kerr (72) were three shots off the lead on 278.
The victory was a long-awaited milestone for Wie, who shot to prominence when she qualified for a US Golf Association event at the age of 10 and played an LPGA tournament when she was 12.
She suffered through highly public struggles with her game as well as a debilitating wrist injury in 2007, but finally earned her LPGA Tour card in qualifying school last December.
