Former U.S. Women’s Open champion Creamer was not put off by the heat in France, as she kept her cool with seven birdies in a bogey-free round.
Creamer claimed the Evian Masters title aged 18 in 2005, though she has not led in a major since the 2010 U.S. Women’s Open at Oakmont, and a wrist injury sustained in this competition in 2017 has seen her form drop, meaning she is now ranked 156 in the world.
Her lead is a slim one, however, with seven-time major winner Inbee Park - who is yet to triumph at Evian - among four players to have carded 65.
Ko Jin-young is one of those tied for second, and she looked in sharp form after winning the ANA Inspiration in April - a victory which saw her move to number one in the world rankings for 12 weeks.
Ko made eight birdies but bogeys on the second and 13th cost her the lead.
