Thirteen wickets fell in the first two sessions at Eastbourne as second division leaders Northamptonshire were bowled out for 110, their lowest score of the season, on the first day against Sussex.

James Kirtley, on his home ground at the Saffrons, took a season's best 6-41, passing 50 wickets for the season in the process.

Both Kirtley and Jason Lewry took two early wickets each as the visitors were reduced to 28-4 and although Russell Warren (29) and Graeme Swann (20) provided some resistance in the middle over, Kirtley had four more victims after lunch as Northants' last five fell for 48 in 12.2 overs.

Sussex's reply began badly as left-armer Paul Taylor removed both openers and Wasim Khan was trapped in front by Darren Cousins before skipper Chris Adams (32no) and Tony Cottey (17no) led a fightback.
