Hull made it six wins in a row following a 31-22 victory over Challenge Cup finalists Wigan at the MKM Stadium.
The Warriors threatened a late comeback, but Hull held on and crossed late through Chris Satae to claim their eighth win of the season.
It’s now two defeats in a row for Matt Peet’s Wigan, who head to Tottenham Hotspur Stadium next Saturday.
Danny Houghton made his 400th club appearance for Hull. Luke Gale returned to the side, named in the halves alongside Josh Reynolds.
Wigan welcomed back several key players after their defeat to Huddersfield last Thursday.
It was a bright start for the hosts, who crossed just three minutes into the clash thanks to winger Adam Swift for an early 4-0 lead. Gale missing the kick.
Darnell McIntosh crossed just seven minutes later thanks to an assist from full-back Jake Connor.
Swift made it an early brace, crossing for his second on 13 minutes to give his side a 12-0 lead.
John Bateman hit back for the Warriors on 17 minutes, before Reynolds scored to restore a comfortable lead of 18-6.
Liam Marshall grabbed Wigan’s second of the day for a half-time score of 18-12 – Gale converting just one of four tries.
HT: Hull 18-12 Wigan
Bevan French made it 18-all on 53 minutes, with Harry Smith converting all goals.
However, Hull hit back swiftly with a try to Tuimavave, who tiptoed down the touchline to score and put his side back in front.
Gale added a field goal to stretch the lead to two scores, but Wigan would not go away and cut the deficit to just one score again with a Liam Farrell try out wide to make it a nervy last 10 minutes.
The Black and Whites were not to be denied though, and put the game to bed with a thundering Satae effort from close range a minute from time to seal a hard-fought win.
