Cambridgeshire overcame Shropshire by 11 runs on Sunday to reach the Minor Counties Knock Out Cup semi-final.
But captain Paul McMahon admitted his side made heavy work of the win, after an inconsistent batting performance.
Cambs made 226 in their 50 overs, with Alan Burton's knock of 70 propping up the innings, before Shropshire could only hit 215 in reply.
"I thought we were a little bit below par, we lost wickets quite steadily," McMahon told BBC Radio Cambridgeshire.
"Although the run rate kept ticking along I felt we didn't get the score we should have.
"I felt if we'd been able to put a few more partnerships together we'd have got closer to 240 or 250."
Burton struggled to find support but received intermittent back-up from Nick Ferraby (34) and Lewis Bruce (27).
Shropshire's innings started poorly, finding themselves 76-6 at one point, and although Tom Cox and Anthony Parker rallied with a partnership of 108 for the seventh wicket, the home side ran out of time to overturn the deficit.
The result sets up a semi-final against Hertfordshire at Harpenden on 3 July and marks a superb turn around for McMahon's men, who have now won four of their last four in the competition after losing their opening fixture against Lincolnshire.
"After the first defeat, to win four games on the bounce has been fantastic," said the former Nottinghamshire bowler.
"It's been delightful to see how people have responded.
"We've got a very confident dressing room and we're one step from Lords."
