Manager Don Cowie praised his Ross County team for coming from a goal down to seal a 3-1 victory against Dundee in Dingwall.
The Staggies are now five points clear of the relegation zone as they move up to seventh place in the William Hill Premiership, only two points off sixth.
Dundee broke the deadlock after four minutes when Simon Murray fired a
spectacular effort from the left wing from 20 yards out which sailed straight
into top right corner, giving goalkeeper Jordan Amissah no chance.
County pushed for an equaliser and their perseverance was rewarded in the 18th minute when a cross from the right wing found Ronan Hale, whose ball into the six-yard box was tapped home by an unchallenged Kieran Phillips.
The hosts came out of the traps flying in the second half when a corner from George Harmon found Akil Wright, who fired a spectacular bicycle kick into the net from six yards.
A minute later it was 3-1 when Phillips sent a ball into the box to find
Chilvers, who fired home from eight yards on his 24th birthday.
Cowie said: “Probably what I’m most delighted about is how we responded after going a goal down so early in such an important game.
“Simon Murray scored a great goal to give Dundee the advantage but we never got spooked by that. I thought we deservedly got back in the game at 1-1, given how we played.
“And I’m really happy, in terms of the way we came out at the start of the second half, to get those two goals.
“I believe we had 20 shots on goal, 10 on target, which is probably a reflection of how good a performance it was.
“That composure is something we’ve spoken about and collectively we knew we had to improve on it.
“When you concede a goal, there’s no drama – it can happen. Murray’s a quality player who has the capability of doing what he did, but it is about remaining calm in that moment and not letting the game get away from you.
“The boys stuck to the gameplan really well in that moment. We got the reward of it in the second half.”
Dundee manager Tony Docherty blasted the state of the pitch at the Global Energy Stadium but had no complaints about the result.
He said: “I have to say that I think the pitch is awful. But we prepared for that all week – that the game wasn’t going to be fancy or pretty and that it was going to be all about first contact and maintain possession in the final third.
“Ross County did all those things better than us. That is hard for me to say as that is something I need my players to do better and that is the reason we had a poor performance and a poor result.”
