The East Anglian Premier League leaders booked their place in the next stage of the ECB National Championship by winning at Kibworth on Sunday.
Lewis Denmark top-scored with 54 as all of the visitors’ top five reached double figures in Leicestershire. His half-century helped Swardeston set a target of 198 for victory.
Michael Eccles struck with the hosts’ reply on nought and when he trapped their opponents’ other opener for one it looked like a routine triumph was going to follow.
Aadil Ali (63) did his utmost to try and make a fist of it but support from elsewhere was never really in the offing. Eccles claimed another scalp, while Sam Thelwell took two wickets, to help restrict Kibworth to 144-8 off their 45 overs and seal a 53-run victory.
Swardeston’s fifth-round trip to Ealing will take place on Sunday, July 12.
