Sussex 401 (Yardy 153, Jordan 92, Footitt 6-120) and 43 for 1 beat Derbyshire 223 (Madsen 63) and 219 (Magoffin 4-44) by nine wickets
Steve Magoffin took a four-wicket haul as Sussex completed their second victory of the season and condemned Derbyshire to a fourth consecutive defeat in the County Championship.
Magoffin snapped up two of the remaining three Derbyshire wickets in the first half hour of the fourth morning to finish with figures of 4 for 44. That left Sussex a victory target of just 42 in the Division One clash at Derby and they knocked off the runs in 5.5 overs for the loss of only one wicket to celebrate a 24-point haul.
Derbyshire were in a hopeless position overnight on 189 for 7, only 11 runs in front, with rain their only hope of avoiding another defeat. Although the skies over the County Ground were grey, the weather was dry and the match resumed on time.
Richard Johnson had shown determination to keep the Sussex attack at bay but he lasted only three more overs as Sussex claimed the new ball immediately. They did not have long to wait for the breakthrough with Johnson pulling James Anyon to fine leg where Magoffin took the catch and Sussex struck again in the next over.
Magoffin beat Tim Groenewald's attempted drive which left Mark Footitt to get the home side past 200 with a couple of fours, before he was caught behind going for another big drive at the same bowler.
It became a case of how long Sussex would take to wrap up the win. They lost Chris Nash for a duck when he edged an attempted cut at Groenewald into Johnson's gloves. But Wells clipped and drove Groenewald for boundaries and Mike Yardy showed he wanted to get the job done in a hurry by driving and pulling the seamer for consecutive fours in the fifth over. Wells hit the winning runs in the sixth over when he lifted Footitt over the slips to the third-man boundary to complete a comprehensive victory for Sussex.
