Match ends, Peterborough United 2, Crawley Town 0.
Peterborough bounced back from Saturday's 2-0 defeat at Rochdale to knock Crawley out of the League Cup.
Conor Washington quickly opened the scoring with a cool finish from Harry Anderson's right-wing cross.
League Two Crawley almost levelled, but Matt Harrold headed Luke Rooney's cross against the post.
The League One side made sure of their passage into the second round when Marcus Maddison fired past Freddie Woodman from 18 yards.
Crawley Town manager Mark Yates told BBC Sussex:
"Lots of encouraging signs, but the disappointing thing is the goals we've conceded. Particularly after the second goal, I just thought we could have been punished a couple of more times just through dropping our shoulders and heads and accepting getting beaten.
"I accept that we are going to make mistakes but it is how we react because I want us to defend solidly and defend properly, but we didn't.
"I want more and more from them all the time, because we had five players on the bench, and to be honest no-one is nailing it down and saying they want a place."
