Exeter Chiefs produced a second-half surge as the Premiership leaders claimed a 32-22 win at Sale Sharks.
The Chiefs trailed 14-10 at the break at AJ Bell Stadium on Friday but ran in three second-half tries to claim a bonus-point victory.
Jacques Vermeulen, Stuart Hogg and Luke Cowan-Dickie all crossed as they maintained an eight-point lead over Bristol Bears.
Second-placed Bristol earned a 33-24 derby triumph over Gloucester, scoring 26 of their points in the first half.
The Bears had three tries in 17 minutes through Max Malins, Henry Purdy and Harry Thacker, with the clinical Semi Radradra’s try sandwiched by efforts from Fraser Balmain and Chris Harris for Gloucester.
Billy Twelvetrees’ penalty shortly after the second-half restart narrowed the gap to nine points but loan signing Ben Earl crossed for Bristol’s fifth try to render Stephen Varney’s score nine minutes from time a mere consolation.
Wasps leapfrogged Sale into third place as they scored 19 second-half points to overturn a 17-13 half-time deficit and defeat Worcester Warriors 32-17.
The boot of Rob Miller kept Wasps in touch in the opening 40 minutes and Gabriel Oghre, Alfie Barbeary Tom Cruse went over in a dominant second period.
