Warrington Wolves missed the chance to restore their two-point advantage at the top of Super League when they suffered a 36-28 defeat at Wakefield Trinity Wildcats on Sunday.
Tony Smith's side trailed 24-6 at half-time and were unable to recover despite a second-half fightback, suffering only their fourth league defeat of the season to remain level on 20 points with Catalans Dragons and Hull FC.
Craig Hall helped himself to a first-half double, while Matty Ashurst and Tom Johnstone also went over with a converted Joe Westerman try all Warrington could muster.
Ashurst went over again early in the second half, but the leaders made a game of it with scores from Daryl Clark, Kurt Gidley and Matthew Russell.
Wakefield were down to 11 men with Anthony England and Danny Kirmond in the sin-bin late on, but Ben Jones-Bishop - who was also sent to the bin in the second half - scored a late try after Westerman's second score set up a tense finale.
The Wildcats have been transformed since Chris Chester took charge and are now up to sixth, while injuries to Ryan Atkins (concussion), Rhys Evans (shoulder), and Kevin Penny (hamstring) compounded Warrington's misery.
Elsewhere, Widnes Vikings have now lost seven Super League matches in a row after they were consigned to a 24-10 defeat at Hull KR.
