Professional career
2001
Pettersen turned professional in September 2000 at age 19 and gained her Ladies European Tour card with an 11th-place finish at the 2001 LET Qualifying School. [2] In her 2001 rookie season, she played in ten events without missing a cut. In her second start as a professional, Pettersen won the Open de France Dames in a playoff over Becky Morgan. [9] She finished second on the Order of Merit and was named LET Rookie of the Year. [10]
2003
In 2003, Pettersen played in five events on the LET, missing no cuts and finished runner-up to Sophie Gustafson at the HP Open. [16] She played a full rookie season on the LPGA, with her best finish a third place at the Chick-fil-A Charity Championship. [5] Pettersen was a captain's pick for the 2003 Solheim Cup and recorded a 4–1–0 record as a member of the victorious European Team. [17]
2004
In 2004, Pettersen played in just four events on the LET, with a best finish of T9 at the Evian Masters. On the LPGA, she began her season late after recuperating from elbow surgery. Pettersen recorded four top-10 finishes including a season-best tie for fifth at the State Farm Classic. [2]
2005
In 2005, Pettersen played in only three events on the LET and nine events on the LPGA because of a debilitating back injury. When she returned, her best LPGA finish was a sixth at the John Q. Hammons Hotel Classic, and she finished tied for second at the Ladies Finnish Masters on the LET. [2] [5] Pettersen registered a 2–0–2 record as a captain's pick on the European Solheim Cup Team, and played for the International team at the inaugural Lexus Cup. [18] [19] [20]
2007
At the start of 2007, Pettersen was selected to represent Norway at the Women's World Cup of Golf but withdrew due to illness before the event started. [22] At the Safeway International she recorded her then-best finish on the LPGA Tour, second place, two strokes behind Lorena Ochoa. A late collapse at the Kraft Nabisco saw her equal that finish, her second best at a major. [10] [23] Pettersen became the first Norwegian LPGA winner at the 2007 Michelob ULTRA Open at Kingsmill, beating Jee Young Lee in a playoff. [24] Pettersen followed up this win by capturing the second major championship of 2007, the LPGA Championship, by one stroke over Karrie Webb, which moved her up to fourth in the Women's World Golf Rankings. On the Ladies European Tour she won the SAS Masters in her native Norway. [25] In October at the Longs Drugs Challenge, Pettersen won her third LPGA victory, beating Lorena Ochoa in a playoff and then claimed wins number four and five in Korea and Thailand. [26] [27] On 31 December 2007, she reached the number two position in the Women's World Golf Rankings, surpassing Karrie Webb and Annika Sörenstam, trailing only Lorena Ochoa.
2008
In January 2008, Pettersen signed a multi-year agreement with Nike Golf to represent Nike in clubs, balls, footwear, glove and bag. [28] Her first win of 2008 came at the rain-shortened Deutsche Bank Ladies Swiss Open. [29]
2010
Pettersen was a runner-up six times on the LPGA Tour in 2010, but did not record a victory.
2011
Pettersen broke her 20-month victory drought in May, when she captured the Sybase Match Play Championship at Hamilton Farm Golf Club in New Jersey. Playing in cool, rainy conditions, she won all six of her 18-hole matches over four days, and defeated, among others, then-world number one Yani Tseng in the quarter-finals, and Cristie Kerr in the finals. In early August, Pettersen won the Ladies Irish Open on the LET with a 198 (-18), six shots clear of the field. It was Pettersen's first victory on the LET in 3 years, her last was the same tournament in 2008, played at Portmarnock Links. In her next start two weeks later, Pettersen won again on the LPGA Tour at the Safeway Classic in Oregon. She came from nine shots back at the start of the final round and shot a 64 (-7) to force a playoff against second round leader Na Yeon Choi. Pettersen won on the first extra hole with a par after Choi put her approach shot in the water to double bogey. The victory moved her world ranking up to No. 2, ahead of Cristie Kerr and behind only Yani Tseng.
2012
Pettersen won twice in October on the LPGA Tour 2012, both in Asia.
2015
Pettersen was involved in a controversy at the 2015 Solheim Cup match in St. Leon-Rot, Baden-Württemberg, Germany, in the second day afternoon four-ball match between Pettersen and Charley Hull for Europe against Alison Lee and Brittany Lincicome, United States. On the 17th green, with the match all square, Lee missed a putt to win the hole. Taking for granted that the next 18-inch putt was conceded, Lee picked up her ball. However, Pettersen pointed out that it was not conceded, and the Europeans won the hole. The European team captain Carin Koch and vice captain Annika Sörenstam tried to convince Pettersen to change her mind and concede the putt, but as it was a fact that Lee had picked up her ball without the putt being given to her, it wasn't a possibility within the rules of golf, for the players to agree on the outcome of the hole and change the sequence of events afterwards. Pettersen/Hull eventually won the match and Europe took a 10–6 lead going into singles. However, United States won the Solheim Cup after a strong come back during the singles play the last day of the match.
2019
Pettersen was picked for the 2019 Solheim Cup European team by captain Catriona Matthew, who was criticized for choosing a player who had been away from golf for nearly two years on maternity leave. Pettersen had played only two events before Matthew chose her and missed the cut in both. At the time, Pettersen was ranked 620th in the world. That pick proved to be astute, as, on 15 September 2019, Pettersen holed her birdie putt on the 18th in her singles match at Gleneagles PGA Centenary Course to defeat Marina Alex, 1 up, to win the Solheim Cup for Europe.
Almost immediately after making the putt, the 38-year-old Pettersen announced that she'd no longer play professional golf. "I think this is a perfect closure," Pettersen said. "A nice 'the end' for [my] professional career. It doesn't get any better." Pettersen retired having won 15 times on the LPGA Tour, including two majors: the 2007 Women's PGA Championship and the 2013 Evian Championship. "Life's changed so much for me over the last year," Pettersen said. "He's [son Herman] obviously the biggest thing that's ever happened for me. But now I know what it feels like to win as a mom. I'm going to leave it like that." [31]
2021
On 29 November 2021, Pettersen was announced as the 2023 European Solheim Cup captain. [32]
