Stacy Lewis made seven consecutive birdies in tying the Evian Masters record with a 9-under 63 in the opening round on Thursday.

Her birdie flurry from holes 5-11, plus two more on 17 and 18, helped Lewis to a two-shot lead over Hee Young Park of South Korea.

Lewis matched three-time champion Helen Alfredsson's round of 63, set by the Swede in 2008.

Park, who used a belly putter for the first time in her career, made five straight birdies on the front nine.

South Korea's Ilhee Lee is three shots behind Lewis in third place.
