Thomas Waldrom and Olly Woodburn scored hat-tricks as second-placed Exeter Chiefs thrashed Worcester Warriors 50-12 in Saturday's Premiership clash at Sandy Park, while Leicester Tigers produced a stunning fightback to beat Gloucester.
The Chiefs went down 36-18 at Saracens in a battle between the top two last weekend, but put that setback behind them by easing to a bonus-point victory over lowly Worcester.
Waldrom has been key to Exeter's success this season and the inspirational number eight starred yet again by claiming three of eight tries in an emphatic display from Rob Baxter's men.
Wing Woodburn also helped himself to a treble as the Warriors' four-game winning run came to a shuddering halt and the Chiefs cut the gap to defending champions Sarries to three points.
Worcester only trailed 17-12 at half-time, but the Chiefs ran riot in a second half in which they ran in 33 unanswered points.
Leicester looked to be heading for a third defeat in four matches which would have dealt a blow to their play-off hopes, but Richard Cockerill's men rallied in the second half to win a thriller 35-30.
Tries from Steve McColl, Henry Trinder and Paddy McAllister and 12 points from the trusty boot of Greig Laidlaw gave Gloucester a 27-13 half-time lead at Welford Road.
But England centre Manu Tuilagi scored his second try of the game early in the second half and Peter Betham also touched down, before Vereniki Goneva crossed seven minutes from time to complete the comeback and move Leicester above Northampton Saints into fourth.
Danny Cipriani scored 20 points as Sale Sharks consigned bottom side London Irish to a 30-15 home defeat, while Harlequins eased to a 46-25 victory against second-bottom Newcastle Falcons at The Stoop.
