Sutton were too good for Crawley in Sky Bet League Two, defeating the strugglers 3-0.
Goals either side of the break from Omar Bugiel and a late finish from substitute Lee Angol made it four wins in five games for Matt Gray’s side.
Crawley, beaten for a sixth successive match, were reduced to 10 men in the closing stages when Joel Lynch was given a second yellow card.
After an uninspiring start from the hosts, Sutton were the first to threaten when Rob Milsom curled a free-kick a yard wide of Corey Addai’s goal.
They took the lead five minutes before the interval when Lebanon international Bugiel got on the end of a clinical David Ajiboye cross and finished past Addai.
Bugiel struck again immediately within two minutes of the restart, registering his fifth goal of the campaign with a sumptuous flick inside the six-yard area that nestled into the top corner.
The victory was sealed in the final moments when Angol beat Addai with a low shot.
