Goals from Jan Vennegoor of Hesselink and Geovanni eased the pressure on Phil Brown as Hull claimed a vital 2-1 win over Wigan.
The pair both struck in the second half of a scrappy Barclays Premier League contest at the KC Stadium to end a dismal sequence of results for Brown's struggling side. Substitute Scott Sinclair headed an 87th-minute reply for the visitors but Hull held on.
It was only the Tigers' second win of the league campaign and just their third in 30 outings since last December.
Nick Barmby's early shot rebounded off Maynor Figueroa but referee Mark Clattenburg dismissed claims for handball. Marney then found space and tried his luck from distance but Chris Kirkland was not troubled.
After a lively opening period, the game went off the boil in the 20 minutes before half-time.
It was not until the second half that the game picked up again, with Wigan's Paul Scharner creating a chance but shooting well over.
Hull grabbed the lead as Vennegoor of Hesselink claimed his first goal for the club on the hour-mark. The Dutchman charged forward to divert Marney's corner past Kirkland with a firm header.
Barmby was soon substituted and Geovanni responded to being handed the armband by grabbing Hull's second in the 68th minute.
Emmerson Boyce gave the ball away on halfway and Zayatte powered into the area and clipped in a fine cross for the unmarked Geovanni to turn in from six yards.
Wigan gave themselves late hope when substitute Sinclair pulled a goal back three minutes from time but Hull held on.
