The Blades ended the Easter weekend with a second victory after an emphatic performance across Yorkshire at Hull.
David McGoldrick netted two early goals to take his tally for the season to 15 and Enda Stevens was also on target before the break.
Boss Wilder made two changes for the fixture. Egan and Hogan returned, whilst Stearman and Madine dropped to the bench, where they were joined by Basham. A lively start saw the sold-out away section is in full voice
The first penalty box action saw Henderson push away a free-kick from Grosicki from an acute angle but the Blades were soon in the ascendency. On 10 minutes, a Fleck corner from the right saw McGOLDRICK lose his marker to head past former United goalkeeper, Long.
McGoldrick was involved in winning the ball back which saw Hogan almost get on the end of a cross by Stevens, who, moments later was on defensive duty, blocking an acrobatic Pugh effort following Grosicki's deep cross.
The Blades, though, were moments away from doubling the lead and it was a special effort. McGOLDRICK wrestled for possession 25-yards out and let fly with a curling shot that flew past Long and into the Hull net.
Hull hit back with a spell of pressure which included a number of Grosicki corners, but the visitors defended well and continued to look a threat at the other end of the pitch - Stevens, with a right-footer, and Hogan, had efforts blocked.
A third Blades goal before the break, though, was forthcoming. On 42 minutes a deep cross from Baldock saw fellow wing-back STEVENS attack the ball with intent and his header was too powerfl for Long.
The first chance of the second half came from a long Hull throw but Pugh was unable to find the target at the back post and United's best chance of the early period after the break was Baldock's cross evading everyone.
Basham was introduced on the hour and United continued to keep Hull at arms' length. McGoldrick continued to be a threat and fired over from 25 yards, whilst the power of Madine was added to United's armoury.
Chances were somewhat limited in the second half, which was pleasing for the Blades. Toral curled an effort over and following a break, Bowen's shot from Dicko's cross was straight at Henderson.
Long denied United a fourth on 80 minutes, saving with his legs from Fleck after the Scotsman linked up with McGoldrick, but the Blades looked comfortable. Hull's final chance saw Toral's shot hit Irvine to sum up their day as United left east Yorkshire with three more points.
