At Arizona State, she was the 2008 NCAA Individual Champion in her junior year, winning by making a 25-foot (8 m) putt at the first hole of a playoff against UCLA's Tiffany Joh in Albuquerque, New Mexico. Surgery on her right wrist in January 2009 sidelined her for over a month during her senior year. In May, Muñoz finished fourth at the NCAA Championships in Maryland to lead the Sun Devils to the 2009 NCAA team title. She was the Edith Cummings Munson Award recipient in 2008 & 2009, the only double winner of the award. Muñoz was also 2006–08 NGCA Academic All-American, 2006–09 First-Team All-Pac-10, 2006–07 NGCA Second-Team All-American, 2009 NGCA All-American and 2009 Pac-10 Scholar of the Year.[1] She graduated magna cum laude from ASU in May 2009 with a bachelor's degree in psychology and a minor in business.
In a final summer of amateur play, Muñoz won the match-play British Ladies Amateur in Wales over ASU teammate and compatriot Carlota Ciganda, then won gold medals (individual & team) for Spain at the 2009 Mediterranean Games in Italy. Although the runner-up in 2008, she opted not to participate in the 2009 U.S. Women's Amateur. She played in three professional majors as an amateur in 2009 and placed T-40 twice.
Professional career
2009
Muñoz turned professional in September 2009, two weeks prior to the first stage of the LPGA TourQualifying Tournament in California, in which she finished second and advanced to the final stage in December.
Back in Spain, she received a sponsor's exemption into the 2009Madrid Ladies Masters, and made her professional debut on 1 October on the Ladies European Tour (LET). After shooting a 64 (−9) in the final round, she won the three-round event on the first playoff hole, defeating former ASU teammate Anna Nordqvist with an eagle putt; Muñoz earned €50,000 and a three-year LET exemption.[2]
In her rookie season of 2010, Muñoz made the cut in her first eleven events, and won over $402,000 in LPGA competition with two top ten finishes. She made the top twenty in the three majors she played, was 30th on the money list, and 17th in scoring.[6] Muñoz handily won the competition for LPGA Tour Rookie of the Year with 704 points; the runner-up was compatriot Beatriz Recari with 419.[7][8]
She won an additional €26,380 in five events on the Ladies European Tour (total 2010 LET earnings were €96,633 in seven events, with €70,253 from the two events co-sanctioned by the LPGA).[9] Muñoz ended the year at 41st in the world rankings.[10]
2012
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.[11] The victory in May vaulted Muñoz from 27th to 19th in the world rankings[12] and from tenth to second on the 2012 money list.
