Wycombe Wanderers upset League One strugglers Crewe Alexandra at Gresty Road to book an FA Cup second-round home date with Preston North End.
Steve Craig netted the opener from the penalty spot on 50 minutes.
Craig was brought down by rookie keeper Ben Garratt, who had fumbled Mark McCoy's 25-yard shot.
Wycombe's FA Cup peak
Wycombe were FA Cup semi-finalists in 2001 but were beaten 2-1 by eventual winners Liverpool.
Second-round opponents Preston's two Cup victories came in 1889 and 1938, when George Mutch's goal was enough to beat Arsenal.
Gary Doherty, an FA Cup semi-final goalscorer with Spurs in 2001, wrapped up a deserved first-round replay win on 70 minutes, prodding in from six yards.
Billy Knott flicked on Anthony Scowen's corner and 33-year-old Doherty slid in to score only his second goal this year.
Crewe boss Steve Davis made four changes to the team
hammered 5-0 at Brentford on Saturday,
including the introduction of 19-year-old Garratt in goal.
But it had little impact and, out of a meagre crowd of 1,695 on a freezing cold night, only the 81 visiting fans from Buckinghamshire returned home happy.
Wycombe's second-round tie against manager Gareth Ainsworth's old club North End will be at Adams Park on Saturday, 7 December.
VIEW FROM THE DRESSING ROOM
Crewe Alexandra manager Steve Davis told BBC Radio Stoke:
"To go out without a whimper is really disappointing. About as low as it can get.
"We're playing League Two opposition. We've got to do better than that.
"There was a low crowd and a lack of atmosphere, but we've got to generate the atmosphere. We just lost our way totally.
"I had to give Ben Garratt a little go tonight. as the other two keepers have been struggling. It's a night he won't forget, that's for sure."
Wycombe manager Gareth Ainsworth told BBC Three Counties Radio:
"It was a great performance. We played the right tactics. The boys were committed.
"Shapes don't mean anything unless you're willing to run and back your team-mates.
"It's a great feeling, a great place to be at the moment and hopefully we can take it into Saturday against Chesterfield.
"It sets up a brilliant tie with Preston in the second round. It's a club close to my heart. I'm sure the boys will be looking forward to that one."
