Gary Holt saw his Falkirk team clinch third place after his first victory in charge.
The Bairns won 4-1 to lift the club above Hamilton and Livingston into the top three for the third time in as many seasons.
Lyle Taylor overtook Farid El Alagui’s goalscoring tally with his 29th of the season, which put the Bairns deservedly ahead after they trailed Mark McLaughlin’s first-half goal.
A good strike from Craig Sibbald, Taylor’s penalty, an excellent worked Kieran Duffie goal and a Sean Higgins tap-in closed the season with a smile at The Falkirk Stadium.
Gary Holt fielded a storng side that included club captain Darren Dods on his final appearance for the club.
And it was Dods who almost opened the scoring when he thumped a corner at Mark McLaughlin from close range. The roles were reversed for the opener, but Falkirk deserved to lead from a positive first half.
It started early with Lyle Taylor racing 60 yards in an elongated one-two passing exchange with Higgins and he reached the return at a stretch but David Hutton gathered.
Stewart Murdoch also stung the palms of the Morton goalkeeper, before the visitors took the lead when Dods blocked two shots close in and McLaughlin forced ther ball over the line.
It gave Alan Moore’s side the half-time lead but Falkirk got what they deserved from the second half.
Sibbald thumped an excellent shot into the top corner just before the hour-mark, then two minutes later Taylor earned a penalty.
His trailing leg was clipped by Craig Reid while clean through and he stepped up to stroke in the Bairns’ second and overtake the Morroccan marker set last season.
The Bairns were completely in the driving seat and extended the lead through a fluent sweeping passing move started and finished by Kieran Duffie.
Holt gave Darren Dods’ his send-off with 10 minutes to go, but rather than milk the applause and standing ovation he jogged off to be replaced by Will Vaulks.
But though Dods’ career at Falkirk was finished, the Bairns weren’t done with scoring and Sean Higgins tapped in a David Weatherston mis-hit to complete the rout.
