Devon director of cricket Roger Newman says his side must take maximum points from their remaining games if they are to have any chance of retaining their Minor Counties Championship title.
Bad weather has seen Devon only record a single one-day win and they are sixth in the Western Division.
They host second-placed Dorset at Exeter next week before travelling to Shropshire for their final match.
"This is a cup final, it's a crucial game," Newman told BBC Sport.
"To give us any chance of retaining our championship we need 24 points from both our games.
"It's totally out of our hands. We've been unfortunate with the weather where other people have been able to get a result when we haven't."
Rob Woodman returns to the squad to bolster a strong batting line-up.
"The batters have done extremely well and we want to back the batters," Newman added.
"At Exeter, we've probably got a result-wicket and obviously it'll take spin on the last day, so with a bit of luck there'll be a result and hopefully it'll go our way."
