Nottinghamshire director of cricket Mick Newell says his team are "living on the edge" in the T20 Blast as they prepare for two crucial group games.
Notts recorded a last-ball win at Lancashire on Wednesday to keep their hopes of a quarter-final spot alive.
"We had to win four in a row, we've won two of those four. We know we're living on the edge going into the last couple of games," Newell told BBC Nottingham.
"If you're going to get a run of wins together then it's perfect timing."
Chris Read's side travel to Durham on Friday before another away game at Leicestershire on 24 July.
Notts have collected 12 points from their 12 matches so far and currently sit in fifth place in the North Group table, with the top four teams to qualify.
"They're all must win games, we have really got to get to 16 points and hope that will be enough, provided our run rate also improves. We have to go to Durham now on Friday and win again," Newell added.
"I thought we were fantastic in the field as we were on Friday night and the influence of Peter is clear to see in the fielding," Newell added.
"I'm encouraged by what I've seen from a bowling and fielding perspective and I'm just waiting for the batsmen to take off."
