WINTER GARDEN, Fla. – On one corner of the range at sprawling Orange County National, Lexi Thompson grabbed a Cobra driver, plugged her tee into the turf and put on a dazzling display of power. Attendees at Demo Day – the exclusive equipment-testing event at the PGA Merchandise Show – were treated to quite an exhibition by Thompson, the 15-year-old phenom who many predict will win on the LPGA in 2011. After her appearance, Thompson answered a few questions from Golfweek.com assistant editor D.J. Piehowski. And check out our exclusive photo gallery, with plenty of Lexi mixed in, by clicking here.
