Captain Stephen Fleming continued his spectacular run of form as Nottinghamshire thrashed Derbyshire inside three days and stay on course to secure promotion.
LV County Championship Division Two
Notts 548-9 declared (Fleming 243, Read 90, Swann 56)
Derbyshire 205 (Adams 4-74, Franks 3-28)
Derbyshire 337 (Patel 3-39)
Notts won by an innings and six runs
Notts 22 points, Derbyshire 4 points
Fleming slammed a Notts-best 243 after winning the toss at Chesterfield, taking charge of the opposition bowlers from the moment he arrived at the crease.
The Kiwi cracked 40 fours and two sixes and was last man out as Notts raced to 548-9 declared at almost five an over.
He shared in two big stands of 186 for the sixth wicket with Chris Read, who himself made 90 off just 113 balls, and 154 with Graeme Swann for the seventh wicket.
A demoralised Derbyshire side then collapsed to 205 all out, with Andre Adams leading the way with 4-74 and Paul Franks picking up three wickets in his second spell.
The hosts proved a slightly tougher nut to crack when following on, but were dismissed in the afternoon session on day three with Samit Patel's left-arm spin claiming three victims.
The result means that Notts need six points from their final match at Division Two champions Somerset in a fortnight, assuming that third-placed Middlesex take maximum points from their home fixture with Leicestershire next week.
