Glendower GC, Gauteng, Johannesburg. Designer: Charles Hugh Allison, 1937; Course Type: Classical, Parkland, Altitude; Par: 72; Length: 7,594 yards; Water Hazards: 11; Fairways: Kikuyu; Rough: Kikuyu; Greens A1/A4 Bentgrass, 12 on the stimpmeter.
Course Overview. Glendower GC is a classical parkland track first opened in 1937 which received a fairly extensive renovation in 2007 with updates predominantly to the green complexes.
At 7,542 yards the layout may look a brute on paper, however being at the altitude of the South African Highveld, which sits around 1,500 metres above sea level, you can scrub around 10% off of those figures and players will tend to convert metres to yards for this type of test, so sub-7,000 yards is a more realistic figure to work with.
The greens are USGA standard and feature relatively speedy A1/A4 bentgrass that the greenkeeping staff are hoping to have around 12 on the stimpmeter by Thursday.
The fairways were narrowed prior to the 2013 South African Open to present a stiffer challenge from off the tee, plus with trees and water awaiting the more errant players this track isn’t a pushover, as was reflected in the scoring when Andy Sullivan won here in 2015 at 11-under courtesy of some tougher conditions from the rough.

Tournament Stats.

For reference, last year’s Jonsson Workwear Open result has also been appended to the data, however this was of course played at Steyn City so should be considered accordingly.

Weather Forecast. The latest weather forecast for the area is here.
A dry start on Thursday is forecast to give way to thundery showers in the afternoon, so some disruption to play is possible. From there on, temperatures will reach around 86 Fahrenheit in the afternoon sunshine and winds will be relatively light at around 10mph after Thursday’s weather has cleared through the area.
Tournament Trends & Key Factors. Basic stats were captured for the South African Open events held here at Glendower back to 2013, plus last year’s Fortress Invitational on the Sunshine Tour, to give us a starting point for this week’s task:
- 2023, Robin Williams (-19). 55.4% fairways (21st), 87.5% greens in regulation (1st), 55.6% scrambling (5th), 1.75 putts per GIR (12th).
- 2018, Chris Paisley (-21). 50% fairways (48th), 77.8% greens in regulation (9th), 81.3% scrambling (2nd), 1.52 putts per GIR (2nd).
- 2017, Graeme Storm (-18). 71.4% fairways (12th), 79.6% greens in regulation (11th), 63.6% scrambling (7th), 1.63 putts per GIR (4th).
- 2016, Brandon Stone (-14). 55.4% fairways (59th), 75.0% greens in regulation (10th), 38.9% scrambling (65th), 1.67 putts per GIR (3rd).
- 2015, Andy Sullivan (-11). 47.6% fairways (41st), 68.5% greens in regulation (31st), 58.8% scrambling (5th), 1.57 putts per GIR (1st).
- 2013, Morten Orum Madsen (-19). 46.4% fairways (32nd), 80.6% greens in regulation (4th), 50% scrambling (28th), 1.71 putts per GIR (16th).
Looking at the winners and their stats above, it’s clear that no common style of play is likely to favoured here, an assertion backed up by 2012 BMG Classic (Sunshine Tour event, played here at Glendower GC) winner Teboho Sefatsa who describes his home track as, “as one of the country’s best courses,” stating that, “The course does not favour the big-hitter or the deft short-game player. You need to bring an all-round game, and you need to play the course gracefully. Simply put, you need to hit straight and then follow up with quality shots.”
The only common factor for the 6 events with data captured has been putting: Madsen was the lowest ranking of the 6 winners at 16th in the field, however Sullivan, Stone, Storm and Paisley all had excellent weeks with the flat stick at this level, and last week’s runner-up Robin Williams ranked 12th for putting on his way to victory here last year on the Sunshine Tour.
Par-5 scoring is another important factor at Glendower and scoring heavily on the long holes is undoubtedly a route to serious contention. Fortress Invitational runner-up Dan Erickson shot an incredible 16-under for the par 5s to eventual winner Robin Williams’ 8-under; 2018 runner-up Branden Grace equalled Erickson’s total when finishing 3 shots shy of Chris Paisley (-10 on the par 5s).
In 2017 Graeme Storm was 9-under for the par 5s with his closest challengers Rory McIlroy and Jordan Smith both producing 13-under totals on the long holes for the week. In 2016 Brandon Stone was -10 for the par 5s and a total of 15 players reached that mark or better for the long holes over the course of the week. In 2013 Madsen was -13 for the week on the par 5s, Kruger was -11, Otto -9, Crespi -11 and Schwartzel -10 which tells a similar story; in tougher, far wetter conditions from the rough in 2015 this was far less important though with eventual winner Andy Sullivan scoring -6 over the week on the par 5s and runner-up Charl Schwartzel one shot better at -7.
Incoming Form: In terms of incoming form, the winners here at Glendower had all shown some signs of life before their victory.
Fortress Invitational winner Robin Williams had won on the Big Easy Tour 2 months earlier and seemed to be rounding into some form before taking the trophy here at Glendower, whereas 2020 Sunshine Tour Championship winner Daniel van Tonder arrived off the back of 6 straight top-10 finishes before winning here at Glendower.
With regards the South African Open events prior to those two results detailed above, Morten Madsen had produced a 66-64 weekend at the Dunhill Links 3 events prior to secure his hitherto biggest cheque of the season at the back end of 2013; Andy Sullivan had also bagged his biggest earning week 3 events earlier by finishing 4th in Turkey; Brandon Stone had secured his first professional title (Lion of Africa Cape Town Open) 2 events prior to winning here in 2016, and Graeme Storm had produced his best effort of the calendar year by finishing 4th at Leopard Creek 2 events before winning here in 2017.
Chris Paisley was making his year’s debut when winning here in 2018, however he’d flashed a little form with a 23rd place finish before Christmas at the Hong Kong Open, including an eye-catching Saturday round of 65:
- Robin Williams: 8/17/37/MC/MC/1/26/6/MC/27/12/22
- Daniel van Tonder: 36/3/8/6/33/MC/5/9/7/6/10/9
- Chris Paisley: MC/55/5/3/MC/12/MC/MC/58/MC/23/MC
- Graeme Storm: 17/7/71/36/62/MC/MC/25/MC/22/4/MC
- Brandon Stone: 7/35/2/9/6/12/MC/23/MC/6/1/18
- Andy Sullivan: MC/52/11/MC/3/17/51/47/67/4/21/MC
- Morten Orum Madsen: 28/58/38/24/MC/14/MC/MC/16/12/51/63
Course Form: Course form doesn’t look overly relevant this week although that assertion can be tempered by the fact that opportunities to play here at Glendower have been fairly few and far between for all but the Sunshine Tour regulars, and even Daniel van Tonder with all of his course experience had only mustered a single top 10 finish here from 8 starts prior to victory in 2020:
- Robin Williams: Debut
- Daniel van Tonder: MC/MC/41/7/55/MC/55/34
- Chris Paisley: 41/MC
- Graeme Storm: MC/32
- Brandon Stone: MC/MC
- Andy Sullivan: 12
- Morten Orum Madsen: Debut
Altitude will negate some of the yardage on the scorecard, and with the prospect of rain softening the turf coupled with relatively light winds, this could be a relatively low-scoring renewal and one where players with a hot putter could well triumph.
My selections are as follows:
