Wycombe Wanderers' relegation from the Championship was rubber-stamped despite finishing the season with a convincing victory at mid-table Middlesbrough.
Gareth Ainsworth's Chairboys started the day three points from safety but their vastly inferior goal difference meant they needed to beat Boro by a huge margin, hope that Sheffield Wednesday won at Derby and Rotherham failed to beat Cardiff to pull off a miraculous escape.
While that sequence of events was never likely, Wycombe dominated at the Riverside Stadium and comfortably led at the break through Fred Onyedinma's clever dinked finish and a scruffy strike from Garath McCleary.
Boro looked well off the pace and the visitors scored a deserved third when Jason McCarthy headed in to ensure they went down to League One with their heads held high.
