VIEW FROM THE COMMENTARY BOX
BBC Radio Derby's Dave Jepson:
"Derbyshire secured promotion thanks to the efforts of Glamorgan at Cardiff, but will now want to go on and win the title.
"And they have every chance of doing so as Hampshire slipped to 142-6 in their second innings, a lead of just 139.
"Earlier, Derbyshire eked out a first-innings lead of just three runs thanks to 57 not out from Whiteley, who shared an eighth-wicket stand of 63 with Tom Poynton (24).
"Given a day of clear weather, it appears Derbyshire's title to win....or lose."
