Match ends, Motherwell 0, Hibernian 3.
Motherwell manager Stephen Robinson wants an apology from referee Andrew Dallas for chalking off Bevis Mugabi's opener in the 3-0 defeat by Hibernian.
The visitors moved to third in the Scottish Premiership thanks to second-half strikes from Martin Boyle, Christian Doidge and Stephen McGinn.
But Motherwell were aggrieved after Mark O'Hara was penalised for a push in teeing up Mugabi's close-range effort.
"The disallowed goal changes the whole game," Robinson said.
"Hopefully, I will get an apology from the referee. He said it was a push in the box. We all make mistakes, but that was a goal. There's no push.
"One nil up at half-time would have changed the momentum of the game."
Hibs are now unbeaten in five and a point clear of Aberdeen having played a game more. And the Easter Road side also have Celtic firmly in their sights, with the champions just a point ahead but having three matches in hand.
Fifth-place Motherwell, despite being awarded two 3-0 victories on Thursday for Covid-19 breaches by Kilmarnock and St Mirren, have gone four matches without a win.
The last two meetings of these sides had failed to yield a goal, so a tight opening 45 minutes was no surprise.
There was little sign of the explosiveness to come from Hibs as they failed to test Jordan Archer, who was making his debut in the Motherwell goal.
Tony Watt should have opened the scoring for the hosts when he rushed into the six-yard box to divert Callum Lang's cross wide.
Mugabi did have the ball in the net shortly before half-time, but O'Hara was harshly adjudged to have fouled Lewis Stevenson in climbing to head the ball down for the defender to bundle home.
Watt blazed over early in the second period before Hibs took command with a much-improved performance. They built a spell of pressure that reaped rewards when Melker Hallberg's cross fell to Boyle and he arrowed in off the upright.
Motherwell were inches from an equaliser when Mugabi's header from a corner bounced back off the post.
A terrific Archer save denied Boyle from close range but the hosts' respite was brief as Doidge planted a side-foot finish into the bottom corner and fellow substitute McGinn did likewise deep into injury time for his first Hibs goal.
Man of the match - Martin Boyle
What did we learn?
Games swing on key moments and Motherwell's disallowed goal proved pivotal. It looked a dubious call from the officials to penalise O'Hara and the hosts' anger was understandable.
However, they had no answer to Hibs' pace and power after the break as the visitors roared to an impressive win.
With Celtic continuing to stutter, second place is not an unrealistic target for Ross' resurgent Easter Road side.
What did they say?
Motherwell manager Stephen Robinson: "Disappointing scoreline but plenty of positives. Key moments and decisions went against us. The goal should stand - I've seen it back. One nil up at half-time would have changed the momentum of the game."
Hibs head coach Jack Ross: "The result is brilliant - it's not often teams come here and win by that margin. First half we weren't as good as we could be, but we hung in there and gave ourselves a platform to win the game.
"There was anger at half-time but every question I posed of the players they answered brilliantly second half. There was a greater intensity in our play and so many aspects of our game were better."
Hibs visit Hamilton Academical next Saturday (15:00 GMT) while Motherwell host bottom club St Mirren.
