Derbyshire 363 and 121 for 2 beat Glamorgan 272 and 211 by eight wickets
Derbyshire skipper Chris Rogers steered his side to an eight-wicket victory over Glamorgan before lunch on the final day at Derby. Rogers made 51 not out as Derbyshire reached their target of 121 with few alarms against an attack which badly missed the experience of offspinner Robert Croft.
Glamorgan knew they needed early wickets to have any chance of defending such a modest total but although they removed Paul Borrington in the sixth over of another sunny morning, they could not build on that breakthrough.
Derbyshire had lost Wayne Madsen shortly before the close on Friday but they went into the fourth day needing only another 95 to secure a second County Championship win of the season. There was some turn and occasional lift for the spinners but although Dean Cosker caused some problems for the batsmen, Glamorgan could not exert any sustained pressure.
It might have been different if Croft had been playing against the county he has tormented down the years but he was controversially left out for the second game running. Croft's only appearance on the ground where he captured his 100th first-class wicket against Derbyshire last year was when he came onto the field in the morning with water for the players and then as a late substitute for Mark Cosgrove who hurt a hand.
Glamorgan must have wished they could have called on him in this game which was finally taken away from them by Rogers and Garry Park who wrapped up a 21-point haul before lunch. Rogers was the wicket Glamorgan had to take if they were to have a chance of pulling of a shock win but the Australian was determined his team would not falter in sight of the finishing line.
Borrington proved to be the only casualty, lbw for 8 to Cosker's left-arm spin as he pushed forward with 40 on the board but Rogers and Park then slammed the door shut. Rogers approach was illustrated by the fact he faced 73 balls before he hit his first four and there was only one more in his 50 which he completed off the last ball of the game, a misfield by Croft.
Park followed his first-innings half century with another assured display and left his mark on Gareth Rees who was struck on the grill of his protective helmet at short leg. The South African straight drove Cosker for the four which took Derbyshire past 100 and was unbeaten on 43 when Rogers sealed a richly-deserved triumph just over 20 minutes before the interval with 68.1 overs to spare.
