Premiership leaders Bristol made light of their injury problems with a long-awaited 37-20 win over Wasps on Friday as they moved 11 points clear at the summit of English club rugby. It was the first time since September 2006 that southwest side Bristol had defeated Wasps, with this win extending their lead over second-placed reigning champions Exeter, who face Harlequins on Saturday. But with the champions decided by play-off matches involving the top four at the end of the regular season, the destiny of the title remains uncertain. Wasps took an early 10-point lead thanks to a Sione Vailanu try but Bristol hit back through Piers O'Conor's try and three penalties from fourth-choice fly-half Tiff Eden. Joe Joyce powered his way over for another Bristol try on the hour mark before Niyi Adeolokun crossed in the corner to put the Bears further ahead. Josh Bassett's try reduced Wasps' deficit but Chris Vui earned Bristol a last-gasp bonus point. jdg/dmc
