The Bulls were briefly back in the contest within five minutes of the restart when Ethan Ryan caught Riley Dean’s up-and-under, found Atkin and then received the return pass to dive over for a superb score on his 200th career appearance.
That proved to be only short respite for the Bulls as moments later Tom Holroyd took advantage of Connor’s superb 40-20 kick to barge over from close range to help re-establish Leeds’ 12-point advantage.
The Bulls were caught out in the back field when Connor’s high kick was not collected by Connor Wynne and Croft pounced to dive over for Leeds’ fifth try of the match.
Leeds scored once more on the hour mark when Cooper Jenkins broke through Eliot Peposhi’s attempted tackle to dive over on the attacking right edge.
Bradford’s day was summed up when Armitage intercepted a pass from Lachie Miller but Ryan knocked on at the vital moment when he threatened to race to the Leeds line.
More magic from Connor then saw Watkins stroll in for another try and Connor slotted the extras to make it seven from seven with the boot.
