Morton’s run without a cinch Championship victory was extended to six games after Michael McKenna’s 87th-minute penalty earned Arbroath a 2-2 draw at Cappielow.
Arbroath took the lead two minutes before the break when Colin Hamilton headed past his brother Jack in the Morton goal.
The hosts quickly restored parity after the break, Gary Oliver turning the ball home from close range.
And Morton went ahead in 55th minute as Cameron Blues slotted into the bottom left-hand corner before McKenna struck late on to secure a point for the visitors with three minutes remaining.
