FA Cup round-up: Bradford City put seven past non-league Tonbridge Angels as Hull City see off Fleetwood Town
The win was just one goal short of matching their biggest winning margin in an FA Cup tie, which came when they beat Walker Celtic 11-3 in a first round replay in December 1937.
As expected, the Bantams dominated the fixture against the non-league side, recording 23 shots at goal and boasting 70 per cent of the possession.
The visitors were 3-0 ahead by half-time thanks to Anthony O'Connor's opener and Billy Clarke's double.
Clayton Donaldson added a fourth 10 minutes into the second half before Austin Samuels fired into the bottom corner on 68 minutes.
Harry Pritchard helped put the icing on the cake for City with an 83rd-minute strike and Connor Wood got in on the act in the first minute of stoppage time to give Bradford their second-straight win - and clean sheet - in all competitions.
Elsewhere, Hull City also progressed to the next round with a 2-0 win over Fleetwood Town. A goal in each half proved enough for Grant McCann's side, who had lost to the same opponents earlier in the season.
Josh Magennis, with his third goal of the season, got Hull off the mark with an acrobatic finish.
Reece Burke made life more comfortable just after the hour as he nodded the ball in from a corner as Hull saw the game out to put their name in the hat for the second round.
On Friday night, Harrogate Town enjoyed first round success over Skelmersdale United with a 4-1 win.
Calvin Miller put Simon Weaver's side ahead after just 46 seconds before the lead was doubled by Mark Beck in first-half stoppage time.
On 68 minutes the game was ended as a contest when George Thomson delivered a free-kick from the right that Jake Lawlor was able to force home from close range with the aid of a deflection.
Aaron Martin added a fourth when he powered an excellent downward header into the net Josh Falkingham's centre.
The away side grabbed a consolation when Danny Mitchley scored the goal of the night with a fine half-volley.
