19 Year old Wins a Major

Image via WikipediaYani Tseng moved one step closer to LPGA Rookie of the Year honors when she won the McDonald's LPGA Championship today. The Taiwanese youngster survived a 4 hole playoff against veteran Maria Hjorth to capture her first LPGA win with a clinching 6 foot putt on the fourth playoff hole.
Yani became the second youngest winner of a women's major and looked extremely cool in the process.
So why is it that the winners on the LPGA Tour are getting younger. Seems like the same phenomenon as occurred in women's tennis in the 80's.
Is it because girls mature earlier or because the talent pool is smaller? Whatever the reason it's a great win for Yani and a big boost for golf in Taiwan.
