Crawley assistant manager Paul Raynor rued his side's wastefulness in front of goal following the 1-1 draw at Plymouth.
Maxime Blanchard's first strike for the Pilgrims, an overhead kick to convert Paul Wotton's floated ball back into the box as Crawley failed to clear a 90th-minute corner, gave the hosts a share of the spoils.
Pablo Mills had headed Town ahead in the first minute of first-half stoppage-time from David Hunt's free-kick, while Tyrone Barnett and Matt Tubbs both had glorious chances to double the visitors' advantage before Blanchard's late effort.
"Obviously you are always disappointed to concede so late in the game and it hurts at the moment but we will dig in and bounce back again," said Raynor.
"Plymouth have got a good home support, they have had some tough times here and they really got behind them. If they got a head of steam up then that could have been a problem, but we were very solid.
"I think Scott (Shearer) only had one save to make in the whole game and that's justification to how much we dominated the game. But you really need to kill teams off and unfortunately we couldn't get that second goal to do it. We should have won the game."
