Northamptonshire's Rob White says their batsmen have had discussions about their responsibilities to the team.
Northants top the County Championship Division Two table, but struggled for runs during the Twenty20 Cup campaign.
White told BBC Radio Northampton: "We have chatted about the fact that the top five or six batsmen have got to score heavy runs.
"We've got to take our minds off the T20 and concentrate on the four-day cricket where we've been doing well."
Although the Steelbacks hit over 150 runs just twice during the Twenty20, there were no such issues in the first half of the Championship season.
"[The batsmen] have been pretty good in the Championship, plus the lower order have been fantastic this year," White added.
"At the top of the order, we've got to make match winning contibutions. If people can get 150s, you're going to win a lot of games and there's a good chance we can go up."
