A second-half penalty was enough to see AmaZulu claim all three points at Sisa Dukashe Stadium on Wednesday as they beat Chippa United 1-0 in the DStv Premiership.
The Chilli Boys came close to opening the scoring early in the game as they found a weakness to exploit. Mokhele Maloisane unleashed the shot and struck the post.
Usuthu responded and built a promising attack which found Mulenga in a good position to score, but his attempt was blocked.
The hosts put AmaZulu under some pressure when they won a free kick in an advanced position. Riaan Hanamub whipped in the set-piece and Augustine Kwem headed straight at goalkeeper Veli Mothwa.
Kwem was once again on the attack as he attempted to penetrate the AmaZulu defence to find Bienvenu Eva Nga. The defence maintained their composure and cleared the danger.
The travelers carved out a chance of their own after Siphelele Mthembu and Thembela Sikhakhane fed Lehlohonolo Majoro who sent in a cross for Siyethemba Sithebe, but his shot lacked conviction.
The breakthrough arrived in the 56th minute when Tapelo Nyongo slotted a penalty to put AmaZulu in the lead 1-0.
Chippa came close to grabbing a last-ditch equaliser as a headed effort was directed goalwards where Mothwa was on hand to make the save and secure all three points for the KwaZulu-Natal outfit.
