Daniel Johnson and Sean Maguire were on target as Preston claimed a 2-0 Championship victory to extend their winning league run to three matches in their last fixture of the year against Coventry.
The Sky Blues, without a win at Deepdale since the turn of the century, entered the empty old stadium on one of the coldest nights of the year.
Not since 2013 had Coventry beaten Preston home or away and they started badly in their bid to address the record.
Tom Barkhuizen had a golden opportunity to find an oncoming colleague in the opening minutes but failed to execute.
It was no surprise that it was Johnson that opened the scoring, burying a close-range effort.
Barkhuizen robbed a dawdling Ben Sheaf in the penalty area and squared the ball to Johnson, who made no mistake with some work still to do.
Diminutive midfielder Hamer looked the most likely to either score or create something for the visitors. Stocky, and slippery on the ball, his knack of getting away from close markers created space for team-mates around him.
That his influence waned as the game progressed was potentially a reason for Coventry's blank.
But it was Preston who extended their lead as Paul Gallagher's free-kick from the right caused chaos in the City six-yard box.
After a few seconds of blocked shots, blocked clearances and an old-fashioned goalmouth scramble, Maguire's toe-poke proved decisive.
The home side, who had won three of their last five at home, without ever looking unstoppable or expansive were efficiently getting the job done.
The Sky Blues exerted pressure in the last quarter-of-an-hour, winning several corners but with only a Leo Ostigard header over the crossbar to show for them.
Down the wings was the second-half plan for Coventry.
Dabo and substitute Sam McCallum whipped balls in at every opportunity but each one was dealt with by the sturdy Preston defence marshalled by the impressive Rudd.
Hamer tested Rudd again from range and the big stopper parried well protecting his team's clean sheet.
But ultimately Coventry will rue not creating enough clear-cut chances and allowing Preston to profit from their mistakes.
On a night where temperatures dipped below freezing, it was Preston who left their fans at home with a warm feeling as they earned maximum points.
