Burns' boot ticked the scoreboard over, and his try before half-time gave Bath a lead they never surrendered.

Will Chudley extended that lead after the interval and Nathan Catt looked to have settled the game, only for his score to be ruled out by the TMO.

Wasps gave themselves hope through Thomas Young's try but too many errors hindered their attempted rescue act.

It leaves Wasps with only one victory from their past 12 matches, but they hold on to fourth place before facing Harlequins at Twickenham on Saturday.

The boot of fly-half Billy Searle put the hosts into a first-half lead but they began to lose the forward battle as Bath asserted control.

Burns scored the opening try, exploiting space on the left wing to dart through a hole and slide in for his third of the season before a long series of pick and drives after half-time saw Chudley finally touch down against the post.

Another forward rumble almost ended with Bath's third try but, although it was ruled out, their lead was healthy enough and their excellent defence closed out a fourth Premiership win of the campaign.

Wasps director of rugby Dai Young told BBC Coventry and Warwickshire:

"I can't pretend we deserved to win that game because we didn't.

"We gave momentum back to Bath every time we had the ball and never gave ourselves a chance.

"I don't think there was any area where we were on top.

"There were far too many turnovers, discipline wasn't good enough, the set-piece creaked and we gave away easy points."

Bath attack coach Girvan Dempsey told BBC Radio Bristol:

"I'm really proud of the boys; there was some excellent stuff out there.

"We put them under huge defensive pressure and to come out and deny them a losing bonus point as well is really pleasing in the context of the league.

"Everyone had a really clear plan of what we needed to beat Wasps and we executed that really well."
