Take a look at this post from 3 years ago where I argued that the JLPGA attracted more talent via its Q-School than the LPGA did.
First point: boy, was I ever right. New JLPGA members (at the time) Shanshan Feng, Hee Young Park, and Bo-Mee Lee turned out to be world-class talents, Shiho Oyama, Teresa Lu, Soo-Yun Kang, Onnarin Sattayabanphot, Kaori Ohe, and Kumiko Kaneda have proven themselves to be among the best on the tour, and several others maintained their membership for years. Yes, Jessica Korda, Pornanong Phatlum, and Tiffany Joh have had varying degrees of LPGA success, and I still have fairly high hopes for Belen Mozo, Pernilla Lindberg, Dewi Claire Schreefel, and Paola Moreno, but the rest haven't established themselves as LPGA regulars.
Second point: oh, how the times have changed! Compare LPGA Q-School and the rookie class of 2014 to the JLPGA's and LET's Q-School results and you'll notice that no prominent or even struggling LPGAers sought out dual membership for 2014 (with Harukyo Nomura giving up her JLPGA membership, there are only 4 dual LPGA-JLPGA members in 2014, Shanshan Feng, Ji-Yai Shin, Momoko Ueda, and Teresa Lu). The LPGA attracted the KLPGA's Mi Rim Lee, the LET's Lee-Anne Pace, Ashleigh Simon, Maria Hernandez, Line Vedel, Joanna Klatten, and Xiyu Lin, and the ALPG's Kristie Smith. Even putting aside Lydia Ko and Giulia Molinaro, who got to the LPGA by other means, the LPGA's '14ers are more impressive than either other tour's. I'd put youngsters Jaye Marie Green, Yueer Cindy Feng, Xiyu Lin, Amy Anderson, Erica Popson, Lindy Duncan, and Natalie Sheary up against the JLPGA's Hikari Fujita and Haruna Taguchi or the LET's Sally Watson, Nobuhle Dalimi, Karolin Lampert, and Nina Muehl with great confidence. And the caliber of the LPGA's returning players--from Lorie Kane to Silvia Cavalleri to Seon Hwa Lee to Lee-Anne Pace to Ashleigh Simon and beyond--is way higher than either other tour's (although I am excited about Na Zhang's comeback on the JLPGA and happy for LET medalist Caroline Martens, who's bouncing back from serious injuries to both her shoulders earlier this season).
Yup, the LPGA is the place to be once again. Even though the JLPGA is attracting more KLPGAers, that's its only advantage over the LPGA now. And you can make an argument that the LET is catching up to the JLPGA in terms of attracting new (but not returning) talent, although that might just mean that it's tougher to break into the JLPGA because it's a stronger tour (in terms of talent and schedule) than the LET.
So congratulations are in order to LPGA commissioner Mike Whan and his leadership team, but even more to the LPGA members who have set such a high standard for the rest of the world and made most of the top players on the planet eager to compete against them. We're going to have to wait awhile for the likes of Sun-Ju Ahn, Bo-Mee Lee, Ha Na Jang, Hyo Joo Kim, Ha Neul Kim, Ariya Jutanugarn, Rikako Morita, Mamiko Higa, and Charley Hull to make it to the LPGA, but it's hard to doubt that most of them will be coming soon. I wouldn't have had such confidence about similar-caliber non-LPGAers in 2010.
