Leopards pulled a goal back in the 43rd minute when Sikhwivhilu scored with a volley after Onyango failed to clear the ball.
The Supersport goalkeeper Denis Onyango scored in the 86th minute when he hammered the ball up field and caught the Leopards’ keeper Mashudu Mamphitha off his line to score his side’s third goal.
The win lifts United near the top of the table on 27 points while Leopards are near the bottom on 14 points.
