County Championship D1, Trent Bridge day three: Sussex 560-5 dec; Notts 165 & 150 by an innings and 245 runs
Sussex 22 pts, Notts 1
Spin bowler Mushtaq Ahmed passed 100 wickets for the season to bowl Sussex to their second Championship title.
The 36-year-old took 9-48 as they beat last year's champions Notts by an innings and 245 runs at Trent Bridge.
It gave him match figures of 13-108 and a total of 102 wickets, just one fewer than in 2003 when Sussex won the title for the first time in their history.
Notts lasted just 16.3 overs before they were all out for 150 as the C&G Trophy winners completed the double.
Rain in Nottingham delayed the start of the third day's play for 40 minutes with the home side set to resume on 50-4.
Once out in the middle, however, the visitors were quick to make inroads into the Notts middle order as Mushtaq bowled David Hussey and Samit Patel in the same over.
Hussey (10) was beaten all ends up by a googly which spun back between bat and pad as he attempted to drive and Patel (22) paid the price for an undistinguished swipe across the line to a straight ball.

The possibility of Mushtaq claiming all 10 wickets in the innings was ended when James Kirtley had Paul Franks (16) lbw to reduce Notts to 107-7.
But the former Pakistan Test player, who has been appointed as their assistant coach for next month's ICC Champions Trophy, swept up the tail to beat his previous career-best figures of 9-93.
Mark Ealham delayed the end with two sixes and four boundaries in his 39 but Mushtaq had him leg before sweeping and another straightforward decision against last man AJ Harris, who was struck on the pad on the back foot, ended the match and sparked the Sussex celebrations.
It was their ninth win of the 2006 campaign, one fewer than three years ago, but two defeats was two fewer than in 2003.
Notts lasted just 16.3 overs on the third day and were left to sweat on the possibility of relegation if Yorkshire and Durham play out a draw in their game, and Durham manage a maximum haul of batting bonus points.
