Javier Hernandez scored twice in the second half, with Jonny Evans, Antonio Valencia and Danny Welbeck also on target, as United recovered from their midweek Europa League exit to make it eight wins and a draw from their last nine league matches. Northern Ireland defender Evans set the ball rolling with his first ever United goal after 21 minutes. And the home side were dealt a further blow six minutes from half-time when defender Ronald Zubar was shown a second yellow card for a sliding challenge on United captain Patrice Evra. From then on, United were in total control, Valencia breaking clear to rifle home a second before the same player set up Welbeck for a third on the stroke of half-time. A close-range Hernandez header made it 4-0 in the 56th minute and the Mexican striker added his second and United's fifth when converting Valencia's cross at the far post. The heavy defeat means Wolverhampton's inferior goal difference has now sent them to the bottom of the table, although they remain level on 22 points with fellow-strugglers Wigan and QPR. Wigan entered the weekend a point behind the other two, but picked up a valuable 1-1 home draw with West Bromwich in one of only two league matches on Saturday. James McArthur had put Wigan ahead from close range nine minutes after the break, but the visitors leveled nine minutes later when former Wigan midfielder Paul Scharner headed home a Chris Brunt corner. Saturday's other league match saw Swansea continue their remarkable first season in the Premier League with a superb 3-0 victory at Fulham. A double from Icelandic midfielder Gylfi Sigurdsson helped the Welsh side move up to eighth position and within sight of a potential Europa League place.
