Durham resumed at the crease on day four with Michael Di Venuto and nightwatchman Mitchell Claydon at the crease with 113 runs required for the victory.
Claydon stuck it out and added 8 to the total before his middle stump was removed by Kerrigan, bringing Dale Benkenstein to the middle with Durham 80-3.
There were numerous lbw appeals from both Keedy and Kerrigan as the morning progressed, but Durham passed the hundred mark without any further wickets falling. Di Venuto and Benkenstein batted with relative comfort with the former scoring a 103 ball fifty and the pair’s partnership passing the half century mark in the 51st over.
Durham were 132-4 after Di Venuto (63) was caught by Croft off Keedy, giving him his tenth wicket of the match.
As the sides broke for lunch Durham were 142-4 with Benkenstein (27*) and Blackwell (4*), who had been dropped at short leg by Mark Chilton off his first delivery, knowing that just 29 runs were required after the break to secure the win.
Durham passed the 150 mark in the 62nd over with just 17 runs needed. With the target down to just 10 Benkenstein was dropped at slip by Horton so he was still at the crease on 41* when Blackwell (20*)hit the winning runs, Durham winning by just before 2.15pm on the final day.
