Wasps completed a late, narrow victory against Worcester at Sixways thanks to an injury time try by Jake Cooper-Woolley which was converted by ex-Worcester fly-half Andy Goode.
The Warriors, whose last home victory in the Premiership was against Wasps last year, looked set for a first victory of the season after Sam Betty's second half try had sent them into an 8-6 lead, before Ryan Lamb's penalty gave the hosts a five-point cushion.
But it was heartbreak for them, as Dai Young's Wasps crossed in the last minute to level things up before Goode sealed the heartbreak with a successful conversion.
Chris Pennell had put Worcester ahead with an early penalty, before Goode kicked two to give Wasps a 6-3 lead after a scrappy first-half.
Betty's try was very controversial: in the build-up, it looked as though the ball had gone into touch, although the try stood.
Wasps then spent the rest of the game camped in Worcester's half, desperately trying to cross before the 80 minutes were up.
Despite not having won all season in the Premiership under Dean Ryan, Worcester knew that victory would have sent them off to 11th-placed Newcastle next Sunday knowing that another win at Kingston Park could put them within touching distance of the Falcons with four games left.
However, after Cooper-Woolley's score, his side were left with just a losing bonus point, their sixth of the campaign.
Worcester Warriors boss Dean Ryan:
"It hurts. We can't hide. It is painful. Sport doesn't necessarily give you everything you think you deserve."
"But I am not going to let us feel sorry for ourselves. I am going to let us get a bit angry, and spend the weekend feeling a little bit tied up with it, and then come back in on Monday."
"We still think we have got a chance in this. It is a pretty tight group - we just don't get the rosy bits at the end sometimes."
"I am really pleased that we found a way to win, really. But in saying that, I don't think we deserved to win the game."
"We defended well and I don't think we were under undue pressure, but with the ball we just looked really nervous. We were edgy, which didn't really allow us to put many phases together and put Worcester under a lot of pressure."
"Sometimes the result is more important than the performance and that was probably a night tonight when it was."
