Warrington hit the front after five minutes when Josh Thewlis evaded the grasp of two Hull players to race clear from inside his own 22 and score a wonderful individual effort.
They got their second when Matt Dufty’s catch and pass found the younger of the Thewlis brothers, Jake, who strolled in to score.
The visitors had a try ruled out in the 22nd minute when Warrington centre Roderick Tai was adjudged to have grounded the ball in-goal before Jordan Rapana dotted down.
Hull clicked into gear on the half-hour mark when Sezer’s terrific line break allowed him to unselfishly pick out Barron to put the visitors on the board.
Eight minutes later, Sezer muscled his way past some weak Warrington defending to drag his side within two points at half-time.
But Warrington responded quickly after the break as Powell found a gap in the Hull defence to dart over for his first Super League try this year, and Sneyd’s simple conversion made it a two-score game.
As Hull began to tire, Dufty dummied to break past some lacklustre defending, and his pass inside set up Australian second-row Fitzgibbon to score a fourth try for the home side.
Hull winger Lewis Martin thought he had reduced the deficit late on when he dived in at the corner but, under pressure from some determined defending from Tai, his left foot was adjudged by the video referee to have been out of bounds.
