Tiger Woods' niece stepped out of her superstar uncle's shadow on Sunday by winning the biggest tournament of her career at the Australian Ladies ­Masters.

Cheyenne Woods, who is the daughter of Tiger's half brother Earl Dennison Woods, held off a strong challenge by Australian amateur Minjee Lee (278) to card a final-round four-under-par 69 and complete a 16-under 276 total for victory.

"This is a huge accomplishment for me," said the world No.363, adding that she hopes her breakthrough will move the conversation beyond merely her surname.

"I've been pro for two years and, for the majority of it, ­people just think of me as ­Tiger Woods' niece so now I have a game of my own and I have a title now."
