Muñoz notched her first LPGA Tour victory at the Sybase Match Play Championship in Gladstone, New Jersey with a 2 and 1 victory over Candie Kung.
In the semifinal round of match play against Morgan Pressel, Muñoz trailed by two through 11 holes. Pressel appeared to have won the 12th hole, which would have given her a three-hole lead over Muñoz, but a slow-play penalty was ruled against Pressel.
Muñoz ended up winning the semifinal match against Pressel, 2 and 1. The victory in May vaulted Muñoz from 27th to 19th in the world rankings and from tenth to second on the 2012 money list.
