Herefordshire's chairman of selectors Ernie Morgan has challenged his side to capitalise on recent good form and overcome Berkshire.
However, Morgan said the game against Berkshire would be a real challenge.
"We have done very well this season. We reached the last eight of the cup."
He added: "We could have beaten Shropshire. That match could have gone either way at the end.
"[Berkshire] have two ex-pros in Shaun Udal and Carl Crowe. They also have some lads who are on the Hampshire staff.
"They have a very strong attack but it's usually a good wicket at Finchampstead. If we come out of that game in a strong position, we can look forward confidently to the rest of the season."
Former Gloucestershire and Worcestershire wicket-keeper Steve Adshead has been starring for the county, with the highest run aggregate 675 in the championship.
However, Morgan said the Minor Counties is not the easy ride for ex-professionals that it once was. "It's no longer a panacea for old pros. Sides are a lot younger than they were five or six years ago.
"You have an age limit where payments are bolstered if you have a side with an average age under-26."
