Leicester 42 Worcester 16
Any remaining hopes of Worcester garnering anything worthy out of the Powergen Cup were washed away by the deluge at Welford Road where monsoon conditions could not stop a storming performance by the Tigers.
Now John Brain's Warriors can focus on their priority - the Premiership.
Any lingering doubts about the Worcester director of rugby's ambivalence towards this competition were dispelled with a simple look at his teamsheet.
Worcester rested half-adozen senior players and Friday night's Premiership encounter with Leeds Tykes will see them re-emerge.
Still, those that remained and the understudies who filled their boots tried their best to make a game of it against a Leicester side deperate to keep alive their chances of qualifying for the knock-out stages.
"We were better than last week - although that wouldn't have been difficult," Brain said. "We had a good second quarter of the game when we scored one try and made two chances that we didn't take.
"But their two tries after half time were cruel. You have to take your chances.
"The positives were we didn't suffer any more injuries and we can introduce another seven fit and rested on Friday."
Leicester coach Pat Howard afforded his team only "six or seven out of ten" for a victory in which George Chuter, Leon Lloyd, Austin Healey, Harry Ellis and Tom Varndell all touched down to earn the Tigers a valuable bonus point with Ian Humphreys and Andy Goode adding four conversions and three penalties between them.
Healey's score was a first in 14 appearances for the former England utility player.
Worcester, who were killed off by those two quick tries early in the second half, responded with a Ben Hinshelwood try and a conversion and three penalties from Shane Drahm.
Tigers might still find it hard to qualify for the semi finals, though, given that Worcester will have nothing to play for against Newport-Gwent Dragons in December's final round of group games.
Howard added: "I don't think the scoreline was really a fair reflection of the game - they gave us a tough time up front.
"At Newport we didn't play well in the wet but now we've got the chance to build on this performance."
Worcester looked a shadow of the side that rattled Wasps at home a fortnight ago and this defeat makes it impossible for them to reach the semi-finals.
The revamped Powergen Cup has not quite caught the imagination of Leicester's army of fans, with 8,642 only half-filling a ground sold out for every home game last season.
The Tigers, though, made a serious declaration of intent in the wake of last week's roasting from the Dragons by making nine changes to their side.
Healey made a rare start at scrum-half with a new-look midfield outside him in Irish fly-half Ian Humphreys, Sam Vesty and Dan Hipkiss.
The pack was bolstered, though, with the return of two Lions forwards in Ben Kay and Martin Corry.
Worcester's first Powergen Cup outing was a comprehensive defeat against resurgent Northampton and their side had an experimental look to it without the likes of injured skipper Pat Sanderson, hooker Andre van Niekirk and veteran prop Tony Windo up front.
Leicester dominated the opening quarter in familiar fashion with Chuter surging through an undefended gap at the front of a line-out in the seventh minute with Humphreys converting and adding a 15th-minute penalty.
The former Ulster fly-half got his wet-weather tactics spot on with a huge upandunder 23 minutes into the game that was spilled by isolated Worcester full-back Jonny Hylton, allowing Lloyd to dribble the ball under the posts for a second try.
Humphreys converted again and his third penalty opened up a 20-6 lead on the half-hour with Worcester down to 14 men after Thomas Lombard was sin-binned for handling on the ground by referee Ashley Rowden.
But they dug in to force the Tigers on to the back foot for the remainder of the half, led by some solid work in the loose with Saiosi Vaili and lock Tim Collier prominent.
Drahm kept them in touch with penalties in the ninth, 26th and 33rd minutes - the latter after Dan Hipkiss was shown the yellow card for killing the ball to level up the sides.
They built up their momentum with a solid passage of play that stretched Leicester's defence before outnumbering them along the left with Kai Horstmann's floated pass putting Hinshelwood into the corner.
Any flicker of a fightback was snuffed out immediately after the break when Worcester shipped 15 points in as many minutes.
Goode, who replaced Humphreys at the interval, opened up with a penalty before a moment of glory for Healey, forced over in the corner by Corry for Goode to convert.
Healey's strike was followed by the sharpest move of the match with Will Skinner breaking along the right and linking with Lloyd, whose assist gave Harry Ellis the score from his first touch.
Tom Varndell had not been on the field long, either, when he profited from some more slick work along the flanks in the 72nd minute when Geordan Murphy's break set up another straightforward score, Goode converting from the touchline.
