Sale Sharks director of rugby Steve Diamond believes his side's first away win of the season at Harlequins could be a defining point in their season.
Dan Braid scored the only try of the game as Sale won 16-12 - their first league win at the Stoop since 2008.
The victory also means that Sharks have won back-to-back games for the first time this campaign and now sit seventh.
"Coming away from home and putting in a performance like that, it is a tipping point for a season," said Diamond.
"You can go on and achieve the goals that you set, and one of the goals that we set is to try and finish in the top half of the division."
Fly-half Danny Cipriani kicked three penalties and converted Braid's try in a scrappy affair, as Sale ended a four-year wait for a Premiership win over Quins.
"We want to have 25 or 30 points by Christmas and that will give us a shot to get in the top six which is really difficult," Diamond told BBC Radio Manchester.
"I keep alluding to it, we've not got a massive squad but when we're all fit you get performances like that.
"I said last week it was more like the Sale we know and it was a really good performance tonight."
