First-half goals from Richie Smallwood and Ryan Longman earned Hull City an impressive and deserved victory at play-off hopefuls Coventry City.
The skipper drilled in only his second Tigers goal after four minutes and Longman crashed home his fifth of the campaign just before the half-hour.
Regan Slater replaced Greg Docherty in the only change from the goalless draw against Birmingham City as the Tigers looked to make it five away games unbeaten.
Coventry were without manager Mark Robins and members of their first-team coaching staff after they tested positive for Covid-19, with Under-23s head coach Luke Tisdale taking charge of the team.
The Sky Blues hit four past Sheffield United on Saturday and looked to strike early, Gustavo Hamer sending a dipping long-range effort into Matt Ingram’s midriff inside two minutes.
The Tigers ran out 1-0 winners on their last visit to Warwickshire in 2011 and opened the scoring on four minutes through an unlikely source.
George Honeyman’s cute reverse pass picked out the untracked run of Smallwood and the skipper steered his first-time drive under the body of Simon Moore from 14 yards.
The keeper, who should have done better, made a comfortable save to hold Tom Eaves’ back-post header from Keane Lewis-Potter’s cross, while Hamer’s curler was pawed away by Ingram.
From the subsequent corner, Matty Godden’s close-range shot on the turn was blocked by a combination of Smallwood and Ingram, with Dom Hyam lashing the follow-up wide.
The Tigers, sharp and incisive, almost had a second as Jacob Greaves’ long ball was taken down beautifully by Lewis-Potter, who continued his run down the left.
He played the ball low across the box but Tom Eaves, completely unmarked in the middle, was agonisingly unable to connect for a tap-in.
Undeterred, Alfie Jones’ 25-yarder was gathered by Moore, who produced an excellent stop to flick Lewis-Potter’s powerful right-footed effort onto the outside of the post.
City were playing with zip and zeal and scored the second goal their sparkling first-half performance merited from the resulting corner on 28 minutes.
Honeyman’s high outswinging delivery broke for Longman, who took one touch to control with his left foot before smashing a fierce drive with his right in off the underside of the bar.
Viktor Gyokeres had penalty appeals waved away as Coventry tried to respond, with Callum O’Hare’s left-footed strike repelled by Ingram after some neat footwork.
Ingram was standing in the way again 11 minutes into the second half, blocking with his chest at the front post after Godden nipped in to meet Fankaty Dabo’s teasing cross.
The Tigers continued to look dangerous – Fleming’s volley dropping wide and Eaves’ near-post effort fumbled behind by Moore.
Chances were coming at both ends; Godden rose high from Hamer’s corner but headed over and Eaves spun his man on the edge of the box but his shot was deflected over by Hyam.
A deflection off Sean McLoughlin made O’Hare’s effort easy for Ingram at his near post after a promising move as the Sky Blues pushed for a way back into the contest.
The hosts were a fraction away from being back in it seven minutes from the end.
Ian Maatsen’s vicious half-volley was blocked by Greaves, ricocheted off Ingram and was blocked again by Greaves, lying behind the line, with his head and eventually cleared.
Coventry were furious not to be awarded a goal - with goalline technology proving not all of the ball crossed the line - leaving the Tigers breathing a huge sigh of relief.
Viktor Gyokeres’ drive was deflected wide by McLoughlin as the visitors’ defence held firm to record a terrific away win.
