The European Tour’s Joburg Open is the second event in the season-long Open Qualifying Series, which consists of 14 tournaments in nine countries on five continents.
The leading three players not otherwise exempt who finish inside the top 10 there earned a berth in the year’s third major.
Coetzee won the Joburg Open, at 19 under par, to clinch his spot. Jeong and Walters finished in a tie for second, along with Tyrrell Hatton (No. 276), but Jeong (235) and Walters (207) got the bids because they had a better world ranking at the start of the week.
Coetzee will be making his fourth career start at the Open. His best career finish was a 15th-place showing in 2011. Jeong tied for 14th as an amateur in 2010, while Walters will be making his first career appearance.
These three players joined John Senden, Bryden Macpherson and Rhein Gibson, each of whom qualified for this year’s Open at Royal Liverpool by virtue of their top-5 finish at the Australian Open.
The next event in the Series is the March 6-7 qualifier in Thailand.
