County champions Durham won for the first time in the First Division this season as they completed a five-wicket win over Hampshire at the Riverside on Saturday.
Durham, bidding to become the first side to win three straight English titles since Yorkshire in the 1960s, dismissed Hampshire for 298 in the visitors' second innings.
That left Durham needing 260 for victory and they reached that target thanks mainly to Kyle Coetzer's 72.
Yorkshire stayed top of the table after a draw away to Kent.
In the Second Division, in-form Australian batsman and Derbyshire captain Chris Rogers made an unbeaten 51 as the Midlands side defeated Glamorgan by a convincing eight-wicket margin.
Elsehwere Stephen Peters's unbeaten 183 was the centrepiece of Northamptonshire's six-wicket win over Middlesex.
