by Brendan Bradford - Another slow start left the Waratahs with everything to do against the Rebels at Allianz Stadium on Friday, but a great second-half performance staved off another Australian derby defeat as the Tahs claimed a 31-26 victory. After trading early penalties, the Rebels dominated the territory and possession stats as a disorganised Tahs defence gave away penalty after penalty before referee Rohan Hoffman finally issued a caution when Tom Carter took out Scott Higginbotham in the air. Two minutes later, the Tahs were down to 14 men when Tatafu Polota-Nau was caught on the wrong side of the ruck. They were quickly down 13-3 on the scoreboard too as Rebels hooker Ged Robinson scored a try from a lineout play off the resulting penalty. [caption id="at
