PHOENIX (AP) - Stacy Lewis won the LPGA Founders Cup on Sunday 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.
Coming off a victory two weeks ago in Singapore, Lewis won for the seventh time in her LPGA Tour career to end Yani Tseng's 109-week run at No. 1.
Lewis closed with an 8-under 64 in perfect conditions at Desert Ridge to finish with a tournament-record 23-under 265 total on the cactus-lined Wildfire layout.
Miyazato was second, three strokes back after a 71. The Japanese star took a four-stroke lead over Lewis and Jee Young Lee into the final round when Lewis was penalized after play Saturday when it was ruled that caddie Travis Wilson tested the sand before Lewis played out of a bunker on No. 16.
