Ross County manager Derek Adams claimed Hibs grabbed an undeserved 2-1 win at Easter Road.
Richard Brittain's free-kick was not enough to cancel out Sam Stanton and Tom Taiwo's early second half goals.
"Overall I think we should have won the game. The least we should have got out of it was a draw," he told BBC Scotland.
"We certainly shouldn't have lost the game. We'll not get a better opportunity than we did today."
With Kilmarnock, St Mirren and Partick Thistle all dropping points, a win would have done wonders for County's chances of avoiding the relegation play-offs, however Adams felt they handed the three points to their hosts.
"In the first half we've gifted Hibernian a two-goal start. I thought it was a soft free-kick we gave away in the first instance and then they score from it," he said.
"The second one we have to do better on the by-line and stop the ball getting across. Hibs are 2-0 up without doing anything.
"We started the game very well and created a lot of opportunities. Hitting the bar, working the goalkeeper, and probably missing a number of gilt edged chances.
"We controlled large spells of the game and put a lot of pressure on Hibernian.
"We have to come here and win. Teams like this you have to win against, ones that are in the bottom half of the table."
