Gloucester took a firm grip on Pool 4 in the Challenge Cup with a win at Worcester while Grenoble beat Agen in Thursday's European action.
The Sixways result leaves Gloucester nine points clear in their pool while Grenoble move provisionally top of Pool 5 ahead of the weekend.
Worcester 22-34 Gloucester
Gloucester scored five tries in their 34-22 victory against Worcester Warriors as they took a stranglehold in the pool at Sixways Stadium.
The visitors opened the scoring in the ninth minute when scrum-half Greig Laidlaw sent over a penalty goal, but the lead did not last long.
Back came the Warriors and with slick handling seeing the ball moved from left to right where wing Dean Hammond finished well, Worcester claimed a 3-7 advantage after Ryan Lamb had coolly slotted the conversion. It was a well-worked try that increased the volume at Sixways.
Gloucester though silenced the crowd on 34 minutes when Henry Purdy finished strongly down the left wing, this after collecting a lovely cross-kick from inside centre Mark Atkinson. Again Laidlaw was on-target off the tee and suddenly the Cherry and Whites were back ahead.
But Gloucester were denied a half-time lead when ex-player Lamb slotted a drop-goal in added time, which meant it was 10-10 at the break.
The Cherry and Whites moved up a gear in the second stanza as a second try from Purdy and then one from replacement Rob Cook pushed them into a 22-10 lead with an hour played. Worcester were in desperate need of the next score and duly followed a spell of Warriors pressure.
That sustained possession paid off and when replacement Mike Daniels scored from the back of a maul, Lamb's extras cut the gap to 17-22.
But Gloucester hit back with an opportunistic try that was set up by Laidlaw and scored by Steve McColl, which sealed the bonus-point win before replacement Billy Twelvetrees added the gloss. Darren O'Shea's late try for Warriors came only as a consolation for the home side.

Agen 20-40 Grenoble
Ahead of London Irish hosting Edinburgh on Saturday, Grenoble moved top of Pool 5 after beating Agen 40-20 at Stade Armandie on Thursday.
Loosehead prop Sona Taumalolo was the star of the show with a first-half hat-trick as the visitors claimed five points on the night.
Grenoble shot out the blocks against their French rivals as a try in the first minute from wing Xavier Mignot set them on their way. And the lead was doubled to fourteen points four minutes later when the impressive Taumalolo went over, with Gilles Bosch slotting the kick.
Agen managed to finally settle into the game and three points via the boot of fly-half Bautista Guemes pulled the scoreline back to 14-3.
However, Taumalolo was over again before the half-hour mark for his brace and with Bosch's extras suddenly the match looked over at 21-3.
Remarkably the former Chiefs and Racing prop claimed his third try of the half on 34 minutes, as Grenoble went in comfortable at 28-3 up.
Agen though came out for the second-half a different team and with Marc Baget, Marc Barthomeuf and Marius Deguilhem crossing in the 47th, 56th and 61st minute respectively, suddenly there was a match on at Stade Armandie as Grenoble were now only leading by 28 points to 20.
But credit to Grenoble who regrouped in the final quarter of the game as a penalty try and a second from Mignot sealed a high-scoring win.
