The Uruguayan had opened the scoring with a first-half header before Jackson Irvine levelled for the Brewers, only to be dismissed minutes later for a second booking.
Grosicki restored Hull’s lead early in the second half with a header before Hernández completed his hat-trick as Hull made their numerical advantage tell to grab a first win under Leonid Slutsky.
GOAL: Hull City 1-0 Burton Albion (Abel Hernández)
A bright start by the Tigers was rewarded with a seventh-minute opener at the KCOM as Hernández opened his account for the season. Markus Henriksen was desperately unlucky not to be the man to break the deadlock as his superbly-struck volley came back off the crossbar, but thankfully the Uruguayan front-man was well placed to head in the rebound, the ball crossing the line despite Stephen Bywater getting a hand to it.
DISALLOWED GOAL: Lucas Akins
Midway through the half, Nigel Clough’s side thought they had found a route back into the game when Akins fired an effort past Allan McGregor. However, the assistant referee on the far side adjudged the Burton to have been in an offside position when the ball came to him after Jackson Irvine had dispossessed Ola Aina. It looked a hard call on the visitors, but the goal was chalked off.
SAVE: McGregor Denies Naylor
After finally exerting some pressure on the Tigers’ goal, the visitors came close to getting themselves back on level terms when a half cleared corner was returned with interest into the middle by Matt Lund and Tom Naylor forced an impressive reaction save from McGregor to keep the home side’s lead intact – a yard either side and it would have been all square!
CHANCE: Grosicki Somehow Misses
The Tigers should have doubled their lead when Kamil Grosicki was put through no goal. His pace took him away from the Burton defence and the Polish international seemed destined to score, only to somehow miss the target with his effort after rounding Bywater.
GOAL: Hull City 1-1 Burton Albion (Jackson Irvine)
The Tigers’ wastefulness came at a cost when Burton drew themselves level 12 minutes before the break. Poor defending from Slutsky’s side allowed Matty Lund to tee up Jackson Irvine on the edge of the box, and the Burton produced a superb finish to find the top corner and level the scores.
RED CARD: Jackson Irvine
Irvine’s joy soon turned to despair though as he was given his marching orders by referee Darren England for a second bookable offence. Having already been booked for a cynical foul on Bowen, the Burton man once again brought down the Tigers’ winger as he looked to advance with the ball from his own box and the man in the middle had no hesitation in producing a red card to leave Burton a man down with seven minutes remaining in the first half.
GOAL: Hull City 2-1 Burton Albion (Kamil Grosicki)
Having scored early in the first half, the Tigers repeated the feat in the second as they needed just five minutes to go back in front. This time, it was Ola Aina getting the better of Lloyd Dyer over on the right and when the full back checked back onto his left foot, he delivered a perfect cross for Grosicki to glance a header into the far corner of the net.
GOAL: Hull City 3-1 Burton Albion (Abel Hernández)
The Tigers extended their lead five minutes later when Hernández grabbed his second of the afternoon, finding the back of the net with a fierce effort that was too strong for Bywater.
GOAL: Hull City 4-1 Burton Albion (Abel Hernández)
Having been twice denied a treble by Bywater, Hernández finally completed his hat-trick on 68 minutes. Played through by Clucas at the end of a powerful surge forward, Hernandez drew Bywater off his line before slotting the ball past him and bagging the matchball. It was his final contribution before being replaced by Adama Diomande.
“Our supporters helped our team change the match because we had a very difficult 20 minutes in the first half. We started very well, we scored a goal and we had chances. But from 20 to 35 minutes we did not play good, we lost control of the match. We changed our tactics at the break and thankfully improved in the second half. I am very happy with the win and the result, and it was good to get our first win of the season.” Leonid Slutsky
“I was unhappy with the two offsides. He (Hernández) was offside for the opening goal. Lucas (Akins) is miles onside when he scores. It was very encouraging how we played in the first half up to the sending-off. The second one was not a booking, I thought it was harsh. The first booking was petulant and I have told him that.” Nigel Clough
