Wrexham's in-form striker Andy Morrell kept up his side's challenge for automatic promotion with a second-half double to condemn Hull City to a 2-1
Wrexham came from behind to win thanks to two Andy Morrell goals
Hull could have opened up an early lead but midfielder Dean Keates failed with a first-half spot-kick.
Visiting keeper Andy Dibble made a superb diving block after Carlos Edwards had fouled striker Stuart Elliott.
Hull did take the lead after 55 minutes when Jon Otsemobor struck for the home side with his third goal in four games.
The Liverpool wing-back showed why Hull boss Peter Taylor would like to sign him on a permanent basis, by racing onto a header from Elliott before shooting into the roof of the net.
However, the Welshmen were soon back on level terms as top scorer Morrell stroked home a confident penalty past keeper Alan Fettis after 67 minutes.
Then Denis Smith's men gained their reward for an impressive passing display to take the lead with 10 minutes remaining.
Steve Roberts made a deep run out of defence and lifted the ball forward for Morrell to score his 29th goal of the season.
Hull almost hit back immediately as Ryan Williams forced Dibble into making a fingertip save with a 25-yard thunderbolt, while Hull forward Phil Jevons went close from just outside the area.
