Hull claimed a third consecutive home win with a controlled 3-0 victory against Birmingham.
Tom Eaves opened the scoring for Grant McCann’s side in first-half injury-time before Kamil Grosicki added a second.
Blues had looked defensively organised for large parts of the game, but they lost concentration when Eaves artfully headed home Grosicki’s corner.
Grosicki then got in on the act after 58 minutes when he delicately chipped the ball over onrushing goalkeeper Connal Trueman following Jarrod Bowen’s defence-splitting pass.
Hull have now won their previous six home games against Birmingham and finished with a flourish when Lewis-Potter thrashed home Eric Lichaj’s precise delivery through the middle after 88 minutes.
Winger Josh Bowler set the early tone when he cut inside from the right and let rip with a smart strike which was deflected for a corner – with Trueman beaten.
Birmingham at least managed to subdue Hull’s early vigour, but the home side remained on top.
That was until the 25th minute, when a mix-up between Leo Lopes and Jordy de Wijs allowed Jeremie Bela space inside Hull’s penalty area.
Birmingham midfielder Fran Villalba underscored the slight shift in momentum with a shot from the edge of Hull’s penalty box after 30 minutes.
Goalkeeper George Long could only parry the ball into a dangerous central area, but Hull’s defence stood firm.
Just when it appeared the hosts’ brightness had dimmed, Eaves scored his fourth league goal of the season.
Hull’s set-pieces had been poor, but Grosicki finally got it right with a perfect left-sided corner from which Eaves glanced the ball over Trueman and into the back of the net.
Birmingham showed more forcefulness in the second half, but it left Clotet’s men open to the counter-attack.
Clotet’s men should have scored after 74 minutes when Alvaro Giminez inexplicably headed Jefferson Montero’s cross wide inside the six-yard box.
Hull had already done enough, though, and later made it 3-0 thanks to Lewis-Potter’s powerful, skidding hit with his right foot.
