The flanker, who only turns 19 later this month, was in the thick of the action throughout and popped up with a late try - his fifth try in seven league games this season - that his work rate and all-action display fully deserved.
Head Coach Richard Hill lavished praise on the young forward after the game and said: "Matt was pretty faultless. He has been away and I have seen one or two of the England Under-20 boys come back from the Grand Slam and their heads are still in the clouds.
"Matt has delighted me because right from the word go at the start of the week his head has been on this club and making sure we win this game. As a result he played exceptionally well."
Kvesic was keeping his feet on the floor after the game, though, and insisted just keeping his spot in the back row and Worcester on the road to the promotion was all the motivation he needed.
"There were things we wanted to work on from last week against Nottingham and today was a better team performance and the boys are happy to get the tries," he said.
"We knew it was going to be a physical game after last week, they wanted to come out and prove a point and we stood up to it well and got a good margin of victory.
"It has not been a problem for me coming back into the club after the England spell. I've had a bit of stick from the boys, but they have been really good on my return and I have learnt the new things quickly.
"It is good to be back and playing for Worcester. Now I just want to cement a place going into the rest of the play-offs.
"It's pretty non-stop at the moment but I am enjoying it. We have a camp in May after the play-offs and then we are into the Junior World Championships. Hopefully I will be selected for that."
Kvesic scored the fifth try of the game - and celebrated in some style (pictured) - as Worcester now turn their attention to London Welsh in a week's time.
"My try was about good build-up from the boys and Tom Arscott beating his man - I was just poaching on the inside and there was not a lot to do except run it in. It's always nice to get on the score sheet," he added.
"It is a shame for Pat (Sanderson) and JC (James Collins) that they are out injured, but hopefully I can step up and fill their boots. When they are back fit I want to keep hold of the jersey.
"The play-offs and the pressure of these games are going to help me develop as a player. We are getting the ball rolling and starting to get going, come the semi-finals - which we have now booked - we will be flying.
"I'm enjoying it and it's brilliant to have guys like Kai (Horstmann) and Besty (Neil Best) around me. It makes me feel good to have those guys alongside me and they help give me the confidence to play my own game.
"It's massive to now perform next week and London Welsh will be going for it. They will be tough and it is very easy to go to their place. But a good week of preparation and we will be ready to get stuck in."
