Romain Wattel of France shares the lead with Scottish pair Richie Ramsay and Andrew McArthur on 7-under par heading into the final round of the Trophee Hassan II.
McArthur and Wattel shot 5-under 67s on Saturday while overnight co-leader Ramsey had to be content with a 71 after hitting five birdies and four bogeys.
South African George Coetzee, who needs to win in order to secure a place at the Masters in two weeks, remains in the mix after a superb back nine at the Golf du Palais Royal. Coetzee is among seven players lying just one shot off the leaders, along with former champion David Horsey.
The tournament remains wide open with only four shots separating the top 29 players.
