A Wayne Rooney hat-trick fired Manchester United back to within two points of Chelsea at the top of the Premier League as the champions inflicted a 4-1 defeat on Portsmouth in Avram Grant's first match in charge.
The England striker converted two penalties either side of a first-time finish from a Ryan Giggs pass to help United to a win that increases the pressure on Chelsea to take something from Sunday's trip to Arsenal.
Giggs completed a good afternoon's work for Sir Alex Ferguson's side by claiming the 100th Premier League goal of his career with a late free-kick.
Portsmouth had appeared galvanised by the new manager but their good early work was undone when Michael Brown pulled down Rooney to concede the opening penalty.
But Rooney re-established United's lead three minutes after the restart and then killed the contest by sending Asmir Begovic the wrong way after Piquionne had brought down Giggs.
The defeat leaves Portsmouth three points adrift at the bottom of the table with just seven points from 14 matches, underlining the scale of the task former Chelsea and Israel manager Grant has taken on.
But City paid the price for failing to convert a string of second-half chances when Joleon Lescott was adjudged to have handled in the area with eight minutes left.
Jimmy Bullard converted the penalty to extend Hull's unbeaten run to four matches.
Guillermo Franco and Luis Jimenez extended the lead before a Steven Fletcher double and a Chris Eagles strike made the score more respectable for the visitors, who finished with ten men after Steven Caldwell was ordered off for a professional foul.
Ivan Klasnic had given the visitors hope of a badly-needed victory by firing them into the lead ten minutes before the interval.
