Wasps boss Dai Young has urged his players to sharpen their clinical edge ahead of Friday night's Aviva Premiership clash against Sale Sharks.
The Londoners head to Stockport just six points above bottom club and relegation favourites Newcastle, who closed the gap by beating London Irish last time out.
"I have no doubt that Newcastle will win a few more games, but it is up to us to control what we can control," rugby director Young said.
"We are six points in front of them, but just four behind Worcester. We can still catch teams in front of us if we can turn the narrow losses into wins.
"I genuinely believe after the last two performances (against Saracens and Exeter) that if we can just improve another 10-15% then that win is not far away from us.
"We are creating good scoring opportunities, but what we need is to turn those chances from being a yard short of the line into being a yard over it.
"We simply need to be more clinical.
"Over the last two games we were the side who looked more likely to score tries, but the difference at the moment is that we are not finishing them off."
Young includes Ospreys loan signing Tom Prydie at Edgeley Park in a team captained by lock Marco Wentzel, while young forward prospects James Cannon and Joe Launchbury also feature.
