PHOENIX - Stacy Lewis won the LPGA Founders Cup to jump to No. 1 in the world, taking advantage of Ai Miyazato's collapse on the 16th hole.
A day after Lewis was penalized two strokes for her caddie's blunder on the short par 4, the American took a two-stroke lead with a birdie on the hole after Miyazato made a double bogey following an errant approach shot that left her with an unplayable lie in a desert bush.
Lewis closed with an 8-under 64 at Desert Ridge to finish with a tournament-record 23-under 265 total on the cactus-lined Wildfire layout. She won the 2011 Kraft Nabisco for her first tour title and has won six times in her last 23 events.
Coming off a victory two weeks ago in Singapore, the 28-year-old Lewis won for the seventh time in her LPGA Tour career to end Yani Tseng's 109-week run at No. 1.
