Walsall moved above Wycombe and out of the League One relegation zone thanks to victory over Colchester.
Anthony Wordsworth fired in from long range to give the visitors an early lead, but the Saddlers hit back with two goals in five minutes.
Emanuel Jorge Ledesma levelled with a stunning free-kick that found the top corner before Mat Sadler found the bottom corner to turn the game around.
George Bowerman rounded off victory with a well-taken headed goal.
VIEWS FROM THE DRESSING ROOM
Walsall boss Dean Smith told BBC WM:
"It's a big win but it was a big performance as well. Going a goal down was hard and we could have ducked. But the lads were brave, each and every one of them.
"We looked like we could create, we looked like we could score, and we looked like we could defend as well.
"I'd spoken to George before the game, wanting an improvement in his work-rate. I know he can score goals but if he ups his work-rate, he'll score even more. He came on and he was hungry, he got his goal and it gave us breathing space."
Colchester manager John Ward told BBC Essex:
"We've floundered a little bit in the final hour of the game. They've come very strong.
"I'm reluctant to say it's a game too far, but it looked that way for some of the boys tonight.
"We suffered a little bit. The best team have won and that was Walsall.
"It was a good start, but we couldn't obviously maintain that."
