Stanley's Sean Maguire praised the patience of his team-mate and double goal hero Piero Mingoia.
Winger Mingoia has been out of the Accrington starting XI for around two months but was recalled for Tuesday's win over Notts County and kept his place for Saturday's League Two clash with Cambridge.
And the lively Mingoia repaid John Coleman's faith in him by blasting home the opener against the Us on 34 minutes and then his deflected effort made it 2-0 on 72 minutes.
Cambridge's Michael Nelson scored a 25-yard wonder goal in the 90th minute to make it a bit uncomfortable for the Reds in the last few minutes but they held on to move to within four points off the play-offs.
"Piero has trained really hard, he is a quality player and he has got his place back in the team and has taken it with two goals," said West Ham loanee Maguire.
"He was brilliant. I have got to know Piero over the last few months and he has worked really hard in training.
"Like all players he needs confidence and hopefully these two goal will mean his is full of confidence and, when he is like this, he is difficult to stop."
Irish attacker Maguire could himself have been the headline act as he unleashed a superb strike which Coleman said would have been goal of the season but Us keeper Chris Dunn tipped it onto the crossbar.
"I was reeling to celebrate but the keeper got his finger tips to it. I was gutted as my dad Paddy had come over to watch and it would have been nice to score for him," added Maguire.
Maguire and fellow loanee John O'Sullivan were recalled to the team after being cup-tied for the Notts County win and Maguire admitted he felt some pressure as he knew he had to perform.
"Both me and Johnno were recalled and we both had a point to prove to keep the momentum from Tuesday going -thankfully we have."
