The Sharks recorded their sixth straight win as Mark Taylor and Magnus Lund when over the whitewash while Daniel Larrechea added three penalties and Valentin Courrent waded in with a conversion and a penalty of his own.
Leicester had to settle for three Ross Broadfoot penalties and scored their only try in the 74th minute when Sale were reduced to 13-men. Andy Goode converted Matt Cornwell’s try.
Leicester were in trouble from the start when flanker Tom Croft was yellow carded in the fifth minute for punching and Larrachea stroked over the first penalty.
Larrachea added two more in a scrappy opening quarter as both heavyweights sized each other up.
Leicester finally put together a solid attack only for a last ditch tackle from Dean Schofield to deny Dan Hipkiss.
Sale No.8 Nathan Bonner-Evans and centre Robert Todd were full of running and the Leicester defence was tested as the game started to liven up.
Broadfoot narrowed the gap to three points with two penalties but winger Tom Varndell, who gets better with each game, was denied a try when Oriol Ripol and Larrachea double bagged him into touch.
Five minutes before the interval Taylor finished off a break from Todd. The Welsh star had been at the centre of a club-versus-country row, after a clause in his contract gave the club priority over Wales who wanted him for their clash against South Africa, but he put all that aside to slay some Tigers rather than Springboks.
Courrent added the conversion to take Sale into the break 16-9 up after Broadfoot had added his third penalty just before the whistle.
Lund’s try at the start of the second half put Sale firmly into the driving seat. Ripol took advantage of a solid Epi Taione run up the centre and Lund was in support for the final pass to dive over.
Courrent missed the conversion but added a penalty in the 56th minute as Sale began to dominate proceedings in the forward battle.Bonner-Evans was sent to the sin-bin for the final 10 minutes for slowing down the ball but still Leicester could not take advantage until it was too late.
Leicester’s only try came in injury time when substitute Cornwell barged over underneath the posts moments after Barry Stewart had become the second home player to be sent to the sin-bin.
