On the evidence of their performance on Friday, it will take a seismic upturn in form for Blackburn to make up ground on the play-off positions, and it was a nightmare start for Ismael's men.
A flowing move, created by Kelechi Iheanacho, led to Conway taking a sumptuous touch and turn before firing Boro ahead with his 12th Championship goal of the season - and the visitors were not done there.
Carrick's side cantered into a 2-0 lead without even breaking a sweat, Rovers keeper Aynsley Pears wrong-footed after Iling-Junior's effort initially looked to be sailing off target before Batth diverted the ball into his own net.
The opening stages proved to be tough viewing for Blackburn chief executive Steve Waggott, chief operating officer Suhail Pasha and head of football operations Rudy Gestede - with the trio in the stands despite fan groups urging them not to attend the remainder of Rovers' home games this season.
Waggott told BBC Radio Lancashire earlier this week he intended to maintain engagement with the club's fanbase despite criticism of the way the club was run - but, after the torrid start, chants against Venky's ownership rang around Ewood Park.
Blackburn did at least show some attacking threat after the break as Cantwell shot narrowly wide from the left of the box and Ohashi's powerful effort from a tight angle forced a fine save from Boro keeper Mark Travers.
But Boro saw out a well-earned win and kept a clean sheet to prove their play-off credentials and lay down a marker with their top-six rivals all in action on Saturday.
