Starting the day seven shots off the pace, Siphayi hit the hot streak after making the turn at two-under, rattling off six birdies, including four in a row on from the 12th to reach six-under for the tournament.
Overnight leader Bryn Flanagan settled for a level-par 72 that left him solo second on five-under, two ahead of England’s Craig Hinton and Pieter Kruger of South Africa.
Talented South African amateur David Meyers was a further shot back in a six-man group on two under as four shots separated the top 10 ahead of the final round.
Siphayi wielded a hot putter on a cold day to take centre-stage, making an improvement of a whopping 10 shots on his first-round.
“I just wanted to get back to level or maybe get a bit lower after shooting a 74 in the first round. I played really well on Monday, but just didn’t make any putts,” said Siphayi, who was placed tied 28th overnight.

“I just worked on the putting and, I guess, I just started dropping them. I started well on the first nine – it was actually quite funny because my golf shoe ripped on the eighth hole and I had to run in and buy some shoes. Maybe it was the new shoes that gave me the six under back nine.
“I made some nice long putts and it just got the momentum going. After the birdie on the 10th it just got better and better. I placed myself really well off the tee box. And yeah, we’ll have to see how it goes in the final round.
“Tomorrow, I’ll have the same game plan. I’ll get here and do my warm-up, get onto the course and like I said, get the lines right so you get one or two putts in and then hopefully shoot really low.”
The cut was made at four-over 148 with 53 players making it to the final round.
An initiative of the Shaikh Maktoum Golf Foundation, the MENA Golf Tour was created in 2011 with the aim of developing golf in the region.
