Devon director of cricket Keith Donohue says it is important his side are focused for their Minor Counties Championship game at Oxfordshire.
Devon have won their last five in all competitions and in their first Championship match.
"We won't be counting our chickens before this Oxfordshire game," Donohue told BBC Sport.
"We'll go into it trying to play some of the good cricket we've played in the last couple of games."
Devon also in the quarter-finals of the MCCA Knockout Trophy last week as they continue to show excellent form after losing their first competitive game to Wiltshire by three runs at the start of May.
"We've had to work hard to manoeuvre ourselves into this fairly good position where we have won five or six on the bounce and naturally we're all very buoyant and confident as a team," added Donohue.
"But the moment you think you've got this cricket lark licked it soon comes back to bite you."
The side sees two changes to the team which won at Dorset, with young bowling prospects Jack Popham and Ben Green added to the squad.
"Ben's only 16 and has just been going his GCSEs," said Donohue.
"But he's has played for West of England and got into the England Under-17 set-up in the last 12 months. He's a very talented young cricketer and has been performing well for his club and we want to give him a go.
"Jack's been training a little bit with Gloucestershire during the winter and is a promising young quick bowler.
"He wants his opportunity and we're delighted he's available to us."
