His share of 18th at the Omega European Masters at Crans-sur-Sierre Golf Club in the Swiss Alps comes after a run of less than impressive results that included four consecutive missed cuts.
After suffering an ankle break while surfing in Bali last year, Coetzee has struggled to regain the form and comfort that saw him reach a career-best 41st in the Official World Golf Ranking.
Although Coetzee has won on the Sunshine Tour this year, at the Dimension Data Pro-Am, he has only recorded one top-10 and two other top-20 finishes on the European Tour, some unpleasant reading for the three-time European Tour winner.
Thanks to back-to-back eagles on Sunday, Coetzee flew up the leaderboard at Crans-sur-Sierre Golf Club to earn some valuable points in the Race to Dubai and he will need to build on that finish if he is to qualify for the top-60 that make it into the DP World Tour Championship.
Currently, Coetzee sits in 94th spot, while his South African compatriots Louis Oosthuizen and Branden Grace challenge at the top in fifth and sixth places respectively.
Charl Schwartzel and Brandon Stone are in the mix at 22nd and 35th place, while Haydn Porteous teeters on the bubble at 60th place, one spot ahead of Thomas Aiken. Jaco van Zyl sits 44th in the rankings thanks to four top-10 finishes this season, including a tie-seventh finish at the BMW PGA Championship.
