by Brendan Bradford - The Waratahs have pulled off another last gasp victory with a 28-22 defeat of the Brumbies at ANZ Stadium in Sydney on Saturday night. Showing grit, determination and confidence in their own ability to rebound in the face of adversity, the Tahs – who trailed for large parts of what was a battle of attrition – were boosted by the second half introduction of Berrick Barnes and snatched a famous win with a try to winger Peter Betham with six minutes to play.  “Berrick changed the shape of the game for us, he gave Foley a bit more room to manoeuvre as well, so we could attack from both sides of the field when we got to centre field,” said Waratahs coach Michael Cheika.
