March 31 (Reuters) - Azahara Munoz burst out of a form slump at an opportune time and Ai Miyazato's renaissance continued at the ANA Inspiration on Thursday as the pair shared the opening round lead in the first women's major of the year.
Spain's Munoz and Japanese Miyazato each carded rounds of five-under-67 at Mission Hills Country Club in Rancho Mirage, California to share top spot, one clear of Scotland's Catriona Matthew, South African Lee-Anne Pace and Japan's Shiho Oyama.
Munoz, who has failed to finish higher than 33rd this season and has not recorded an LPGA top 10 since August last year, carded six birdies but dropped back with a bogey on her final hole.
