Victor Letsoalo scored on either side of the break as Bloemfontein Celtic claimed the bragging rights in the Free State Derby.
The victory was enough to see Siwelele move into fourth position on the PSL standings with 19 points from 12 league matches.
It was a clear strategy from the home side which was to press high up the field and shoot from range in order to unsettle their rivals.
Deon Hotto and Lantshene Phalane certainly lived up to that as both players tried their luck from miles out though they were unable to trouble the opposition goal.
Phunya Sele Sele whose midweek match against AmaZulu was called off because of bad weather in KwaZulu-Natal, they were the more energized and enterprising of the two teams in the first period.
In fact, the home side was so much better going forward than their opponents and registered a total of 10 attempts at goal with three hitting the target while Stars only had three shots at goal with none finding the target.
Veselin Jelusic's charges eventually saw their resilience pay off when they opened the scoring in the 30th minute through Letsoalo. A quick one-two between the former Baroka man and Mabena in the Stars 18-yard box saw the latter sell a dummy to the visitors' defence, before laying it off for Letsoalo with a cheeky tap as his snap shot from close range landed in the roof of the net.
Luc Eymael's side came out the better of the two sides in the second half, playing a fast-paced game and soon had a corner kick. Mohammed Anas found himself unmarked in the box but the Ghanaian striker failed to connect his header as the ball sailed over the Celtic crossbar.
The home side turned possession around and pressurized Stars so much that a defensive error almost allowed Celtic the opportunity to double their lead when Sangare latched the ball onto the path of an opposition player, but Ronald Pfumbidzai could only see the Ea Lla Koto shot-stopper recover well to stop his shot which fell into play before been cleared away from danger.
Former Kaizer Chiefs man Lucky Baloyi doubled his side's lead shortly afterwards. The midfielder received the ball on the edge of the Stars box from Letsoalo before unleashing a thunderous shot into the top right corner which Sangare could do nothing about.
Ea Lla Koto fell on the back foot from there on as Jelusic's men dominated proceedings, especially in the middle of the park, thwarting off any danger from the opposition going forward.
Patrick Tignyemb was hardly tested as Celtic kept things tight at the back. As the club's captain, the Cameroon international continued to lead from the back, steering his ship in the right direction with his constant communication.
The final nail in the Stars coffin was completed in the 65th minute when Letsoalo got his second of the match. The pacy forward was played through on goal by Hotto and the 24-year-old made no mistake as he easily wrong-footed Sangare before placing the ball at the near post.
The visitors slipped to 10th on the log with 16 points from 13 league matches after this defeat.
