Chiefs and Exiles bag famous wins
Exeter and London Irish enjoyed notable successes in the Aviva Premiership on Saturday with wins over Northampton and Harlequins respectively.
Jonathan Joseph inspired London Irish as they destroyed Northampton's unbeaten record at the Madejski Stadium with a 39-17 victory.
The England centre touched down for the opening try and he played a key role in scores by David Paice and Topsy Ojo as London Irish turned the Premiership table on its head.
Jamie Gibson wrapped up the Exiles' first bonus point of the season with their fourth try to cap another outstanding individual display.
By the time Ken Pisi and then Phil Dowson scored late consolation tries for Northampton, the Saints already trailed 33-3 and their goose had been well and truly cooked.
Exeter Chiefs celebrated their 50th Aviva Premiership match with a try-scoring bonus point victory at Sandy Park as the reigning champions Harlequins missed the opportunity to go back to the top of the table losing 42-28.
Two second-half Jason Shoemark tries in five minutes helped Exeter to victory.
Brett Sturgess's try put the hosts ahead, but last season's champions hit back to lead 18-16 at half-time with scores from Ugo Monye and Nick Evans.
Shoemark's double was added to by tries from Ben White and Sireli Naqelevuki, while Gareth Steenson took his tally to 17 points with the boot.
Karl Dickson went over for the visitors but Exeter claimed a famous win.
Gloucester fought back from an alarming early deficit to make it five Premiership games unbeaten with a 16-10 win over Bath.
Bath made a powerful start in pursuit of a first win on Gloucester soil since 2006 after fly-half Stephen Donald converted his own first-minute try and then kicked a penalty.
But Gloucester responded from 10-0 adrift through two Freddie Burns penalties, before he added the extras to full-back Rob Cook's 50th-minute touchdown and then slotted a late drop-goal.
