Yes she has played well so far this year. She also finished 3rd, 24th 7th, and 11th in her last 4 tournaments last year.
As strange and unusual that putting stance is, it is working. Michelle finished #113 on the LPGA in Putts per greens in regulation in 2012. She improved to 25th last year.
As far as the people here that say she does not want it bad enough, I disagree.
Michelle has finally found a peaceful place. She no longer has the pressure of having to live up to that 13 year girl she was. She now is comfortable just being a very good player that will contend most weeks and win once in a while.
