Colchester manager Joe Dunne said an explosive start built the platform for their thumping 4-0 home win over Stevenage.
Dunne enjoyed his biggest win as U's boss to leave Stevenage three points adrift of safety in Sky Bet League One.
Dunne said: "We made a very quick start and there were also some quality goals, so overall I'm delighted.
"We'd talked about keeping the players as fresh as we possibly could and we got the early goal and gained confidence from that.
"We got a bit of fortune with our first two goals, but they were good finishes and that gave us a real platform.
"I thought it was a wonderful all-round performance by Craig (Eastmond).
"He scored two and had a very big influence on the game - it's in his locker if he wants to take it.
"We haven't had too many big wins here.
"It's the first time in a long time where we've kept an attacking mentality in terms of the changes, instead of going more defensive.
"There were a lot of good performances - Sam (Walker) made a wonderful save at 3-0 which was important and concentration levels were high."
Blair Turgott tapped Colchester ahead in the10th minute, after Stevenage keeper Chris Day had failed to hold onto Brian Wilson's cross.
And Day was at fault three minutes later when he flapped at Luke Garbutt's cross and Jabo Ibehre volleyed home.
It was 3-0 nine minutes later when Eastmond side-footed home from Turgott's assist.
Day then palmed away Garbutt's excellent free-kick, but Stevenage improved after half-time, with Luke Freeman denied by U's keeper Sam Walker and Luke Jones' header hitting the crossbar.
But Eastmond tapped in Sanchez Watt's low cross with 13 minutes remaining to wrap up Colchester's win.
