Cape Town - AmaZulu and Bloemfontein Celtic could not be separated in their rematch after playing out to a goalless draw at the King Zwelithini Stadium on Wednesday.
The hosts came into the game fresh from their victory over SuperSport United last weekend and could have taken the lead within seconds of this Absa Premiership encounter kicking off.
Sadat Ouro-Akoriko's long ball found Camaldine Abraw, whose flick sent Ovidy Karuru through on goal, but the Zimbabwean's half-volley flew over the crossbar.
The KZN outfit wanted a penalty in the 20th minute when Karuru was brought down by Ronald Pfumbidzai in the box, but the referee waved play on.
Usuthu were doing all the attacking but couldn't put together a final ball to unlock the opposition defence.
Augustine Ramphele found space just outside the box in the 35th minute and unleashed a powerful drive, but Tignyemb leapt well to his right to pull of a comfortable save.
Following a disappointing opening half, Siwelele flew out of the blocks after the restart and enjoyed the opening exchanges.
Vusi Shikweni decided to try his luck from long range five minutes into the second half and his swerving strike forced Siyabonga Mbatha into an athletic save.
It looked like a sign of things to come but instead both teams looked happy to settle for a point with goalscoring chances few and far between.
The visitors had an opportunity to steal the three points in added time, but Ndumiso Mabena blazed over from a free-kick just outside the area.
AmaZulu finished with a flurry but Tignyemb was determined to keep his clean sheet. He produced an excellent fingertip save to deny substitute Siyethemba Mnguni, whose low shot almost created some late drama.
