BBC Radio Derby's Dave Jepson:
"Hampshire finish the day with a lead of 222 in a game that is pretty even.
"Derbyshire are going to have to bat pretty well on Wednesday to make sure they get up to and in front of this Hampshire total.
"Their batting hasn't been too strong in recent weeks, but they're going to have to pull something out the bag in the next few days."
