But she hit more than two-thirds of her fairways and 83-percent of greens. Thompson&#39;s bugaboo this early in her career has often been putting, but when she has a decent week with the putter she&#39;s always a threat to win.

Her ability to handle the success and disappointment inherent to this game testifies to a level of maturity that I believe makes her capable of handling the emotional rigors of professional golf at the highest level. Therefore, effective at the start of our 2012 season, Lexi will officially become a member of the LPGA Tour.&#34;<br/><br/>Whan had previously granted Thompson a waiver of the minimum age so that she could take part in this year&#39;s 2011 <a href="https://www.thoughtco.com/lpga-tour-qualifying-school-q-school-format-and-past-winners-1565818" data-component="link" data-source="inlineLink" data-type="internalLink" data-ordinal="1">LPGA Q-School</a>.
