Cameron Spencer/Getty Images Waratahs coach Rob Penney is under immense pressure to retain his job after another defeat to the Western Force. The Waratahs fell 20-16 to the Force at Bankwest Stadium on Friday night, earning the unwanted tag of being the first team to lose to the Force since they returned to Super Rugby. It’s the first time the Force have won a Super Rugby match in 1329 days. The four-point loss wasn’t an embarrassment but given the visitors played with just 14 men for the final 15 minutes after Andrew Ready punched Hugh Sinclair in the head in a post-ruck scuffle, the match was there to be won.
