Louis Oosthuizen

In December 2019, Oosthuizen played on the International team at the 2019 Presidents Cup at Royal Melbourne Golf Club in Australia. The U.S. team won 16–14. Oosthuizen went 2–1–1 and lost a 3 up lead to halve his Sunday singles match against Matt Kuchar.

On 9 December 2018, Oosthuizen won the South African Open. This event was co-sanctioned by the European Tour, Sunshine Tour and the Asian Tour.

On 13 August 2017, Oosthuizen finished joint runner-up at the PGA Championship, finishing a career "second-place" Grand Slam.

Oosthuizen finished as a joint runner-up in the 2015 Open Championship at St Andrews after losing in a four-hole aggregate playoff during a Monday finish to the event. He was in the final group tied for the 54-hole co-lead but needed to birdie the 18th hole during his final round to tie the lead at 15-under and join Zach Johnson and Marc Leishman in the playoff. In the four-hole playoff, he birdied the first hole alongside Johnson, but could not convert his birdie putt on the second hole, giving Johnson a one-stroke advantage. All three players bogeyed the third hole and after Johnson missed his birdie putt on the final hole, Oosthuizen had a 15 footer to extend the playoff to sudden death. However his putt caught the lip on the low side and he finished at even-par, one stroke behind Johnson. This was Oosthuizen's second consecutive runner-up placing in a major championship, following the 2015 U.S. Open.

In January 2014, he retained the Volvo Golf Champions title by one shot over Branden Grace.

Oosthuizen became the fourth man from South Africa to win the Claret Jug – following Bobby Locke, Gary Player, and Ernie Els – and moved to 15th in the Official World Golf Ranking, leapfrogging fellow South African Retief Goosen in 16th position.

On 13 January 2013, he won the Volvo Golf Champions, shooting a six-under-par 66 final round to win the title by one stroke.

He played on the European Challenge Tour in 2003 and has been a member of the European Tour since 2004. In 2009, he finished 31st on the Race to Dubai. On 10 September 2012 he reached the top 10 of the Official World Golf Ranking for the first time in his career.

On Sunday, Casey closed the gap to three shots on the 8th hole, before Oosthuizen drove the 9th green and made a long putt for eagle. On the 12th hole, Oosthuizen made birdie, while Casey hit his drive into a gorse bush, and wound up making triple bogey to give Oosthuizen an eight-shot lead. In the end, Oosthuizen shot 71 on Sunday, and 16-under-par 272 for the championship, to win by seven strokes. His 272 was the second lowest in St Andrews history. Casey eventually finished third with Lee Westwood taking second.

Oosthuizen was runner-up at the 2012 Masters Tournament. In the final round, he scored an albatross on the second hole of Augusta National Golf Club. This was only the fourth ever albatross in Masters history, and the first to be televised, as well as the first ever on that hole. Oosthuizen took the outright lead of the tournament with this exceptional shot, and maintained the lead until caught on the 16th hole, by Bubba Watson. He was eventually defeated by Watson on the second hole of a sudden-death playoff. He won his fifth European Tour title at the Maybank Malaysian Open the following week.

In the second event of the 2012 PGA Tour FedEx Cup Playoffs, the Deutsche Bank Championship, Oosthuizen held the 54-hole lead by three strokes and came close to his first victory on US soil, finishing second to Rory McIlroy by one shot.

On 10 September 2012, he reached the top 10 of the Official World Golf Ranking for the first time in his career. He finished the season ranked third on the Race to Dubai.

In March 2010, he won his first European Tour event at the Open de Andalucia de Golf. He also won the 2010 Masters Par 3 Contest.

Oosthuizen entered the 2010 Open Championship at St Andrews ranked 54th in the Official World Golf Ranking, and only having made one cut in eight major championship appearances. He shot a 65 on the first day, placing him in second place, behind a 63 shot by Rory McIlroy.

Oosthuizen finished the 2010 season in 10th place on the Race to Dubai, posting three further top-10s after his major win. In January 2011, he claimed his third European Tour title, and his sixth in his home country, winning the Africa Open in a playoff. In 2012, Oosthuizen successfully defended his title at the Africa Open with a two stroke victory over Tjaart van der Walt. His success was helped by a second round 62, which took Oosthuizen to the top of the leaderboard at the halfway stage and from there he held on for victory.
