South Africa's Louis de Jager made the most of some "home" comforts to open up a sizeable lead at the halfway stage of the Magical Kenya Open, but Michael Hoey slipped off the pace after a tough second round.
Hoey made a good start on Thursday, finishing on five-under-par in a tie for fourth place after a round of 66.
But the Antrim man's three-over 74 today left him two-under for the tournament, ten shots of the leader at the halfway point.
Another Northern Irishman, Cormac Shavin, sits beside him on the leaderboard. He carded a level-par 71 to safely make the cut.
Tramore's Robin Dawson was not so lucky. The damage was done in a disastrous opening 12-over 83 but he did produce a highly commendable 68 on Friday to take some positives from the tournament.
Gavin Moynihan also missed the cut, signing off on two-over overall.
De Jager added a second round of 66 to his opening 64 at Karen Country Club to reach 12 under par, four shots clear of fellow overnight leader Jack Singh Brar and Spain's Adri Arnaus.
South Africa's Justin Harding, who is seeking back-to-back wins following his victory in Qatar, shots a superb 65 to lie a stroke further back alongside India's Gaganjeet Bhullar and Italy's Guido Migliozzi.
De Jager, who came through the Qualifying School at the sixth attempt last season, carded seven birdies and two bogeys as he enjoyed being back in Africa following events in Oman and Qatar.
"I told the guys when we played a practice round on Tuesday, after the desert you could feel you were in Africa, back in our continent," he said.
"You get used to the feel of the kikuyu (grass) and the ball travels the same as back home in Pretoria, distance-wise, so it really feels like we're back home.
"I had to find my feet a bit at the start of the season but I'm felling comfortable out here, this is where I belong.
"I started off birdie-birdie and it got me in the right mindset for the round. I kept it going, kept it on the fairways, kept hitting the greens and made a few putts."
Singh Brar held the outright lead after an early birdie and picked up another shot on the eighth, but dropped shots on the 12th and 14th before a birdie on the 17th in a round of 70.
