Preston North End picked up only their second home win of the season after scoring three second-half goals to see off Middlesbrough at Deepdale.
After a goalless first half, Brad Potts diverted an Andrew Hughes effort past Marcus Bettinelli to give the hosts the lead.
Scott Sinclair rolled the ball into the far corner with nine minutes left to double their advantage.
Substitute Emil Riis Jakobsen grabbed a deserved third late on, cutting in and drilling below the Fulham loanee.
Boro toiled, with Marvin Johnson forcing two good saves from Declan Rudd, but otherwise, they were unable to trouble North End.
