The World No. 143, who also opened with 68, will play out of the fifth-to-last twosome on Saturday with countryman Garrick Higgo. He’s chasing his second worldwide win in the calendar year, joining the Dimension Data Pro-Am five weeks ago, which is a co-sanctioned event by the Challenge Tour and South African Sunshine Tour. The South African also owns three top 10s on the European Tour in 33 events, including a best of runner-up at the 2020 Joburg Open last November, and led that tour in Driving Distance in 2020 (340.7 yards). On nine (of 14) fairways and 12 greens in regulation, he lost 0.090 strokes off-the-tee but gained 2.226 approaching and 2.035 around-the-green. The 21-year-old squared four bogeys at 10, 16 (lost tee ball), 7 (3-putt from 60'9") and 8, camouflaged by five circles at 11, 13, 1, 2 and 9, and a hole-out eagle-2 at 3 from 75'5" away from a waste bunker. He posted 0.856 SG: Putting with 27 total putts, including a par-save at 15 from 14'7", his longest putt made on the lap. At the halfway point, Nienaber ranks 16th in SG: OTT (2.402), 21st in SG: Approach (2.748), 33rd in SG: Around (0.944), 18th in SG: Putting (2.793), and No. 1 in Driving Distance (measured drives) at 361.1 yards. Post-round: “It makes me really excited (being in the mix). I’m really pleased with what I did the last two days. Growing up watching the PGA TOUR, is where I want to be, and it’s really nice to start off like I did.”
