In another blow for Sale, prop WillGriff John was forced off at half time after failing a head injury assessment, ruling him out of Wales’ Six Nations’ opener against France next week.
They hade been more than competitive in the first half, despite losing five of their first-choice pack to England call-ups, as they sought to extend an 11-match winning streak in their northern fortress.
The forwards powered the ball to within a metre of the posts and when Rob du Preez slung a long pass over the top, Reed showed his finishing ability by stepping inside the cover to score.
Du Preez added a penalty but after Louis Schreuder forced an error at the breakdown, Bath went onto the attack and McConnochie sprinted over out wide to close the gap.
Sale stormed forward again and when Tom O’Flaherty picked up Carpenter’s grubber and was held up just short, du Preez picked up and darted over on the blindside, before adding another penalty, to put Sale clear again.
Bath struck back just before the break, with McConnochie again stretching away from the home defence, and Russell’s conversion setting the match up nicely for the second half.
Bath were superb in the second 40 minutes, with Russell pulling the strings.
He seemed to have set up Ojomoh for a quick try, but the wing had juggled the ball against O’Flaherty’s shoulder to knock on before diving over, with a video review chalking it off.
Eight minutes later, Bath cycled through 20 phases of attacking play and this time Russell’s sweeping pass found Joe Cokanasiga and when he was stopped, Ojomoh powered over with two tacklers unable to stop him.
Russell’s conversion and subsequent penalty took him past the century mark for the campaign, and then he produced a marvellous piece of quick thinking in a pivotal moment to turn a difficult moment into a 13-point lead.
Reed had shot through a rare Bath gap but when Sale were penalised at the breakdown, Russell quickly kicked the penalty long despite Sale claiming he had not done so from the mark.
Carr-Smith was on the fly-half’s wavelength and sprinted the length of the field to kick on and score.
Carpenter barged his way over to make the last couple of minutes interesting but Russell had converted Carr-Smith’s try and then added his late penalty to seal the win.
