Mark Cueto marked his first Sale start for two months with a try for the Guinness Premiership champions but his effort proved in vain as Wasps, trailing 10-0 after only 18 minutes, hit back to secure victory, with fly-half Alex King kicking 16 points.
Sale had opened up their 10-point lead when fly-half Rhys Jones landed a long-range penalty and added the conversion after flanker Chris Jones put Cueto over in the right-hand corner after 18 minutes following a sustained spell of pressure.
But Wasps, with the pace of discarded England winger Tom Voyce proving a constant threat, hit back. Voyce had a try disallowed when the video replay showed he had not touched down properly after squeezing between Lund and Sale scrum-half Richard Wigglesworth.
But he sparked the second try with the break which enabled centre Jeremy Staunton to quickly move the ball on for Tom Rees – one of the England replacements in Dublin – to score in the corner. King converted and kicked two penalties, and Rhys Jones made one for Sale, as Wasps levelled at 13-13 three minutes into the second half.
King’s third penalty, after Cueto had been punished for a high tackle on Voyce, put the home side 16-13 ahead in the 57th minute and he kicked another eight minutes later. Wasps stretched their lead with a 70th-minute try from Staunton, converted by King.
And even though Sale hit back with a 79th-minute try from centre Chris Bell, Rhys Jones missed the conversion and then a penalty which would have secured his side a consolation bonus point.
