Widnes Vikings remain rooted to the foot of the Super League table after throwing away a 22-point lead in a home defeat to Hull FC on Sunday.
Hull looked to be heading for a shock reverse when tries for Chris Houston and Rhys Hanbury were followed by a first-half brace from Patrick Ah Van.
However, Lee Radford's men responded superbly, running in six unanswered tries thereafter to triumph 33-22 and move up to second in the table, one point behind leaders Castleford Tigers.
Jansin Turgut started the Hull fightback a minute before half-time, but Widnes still held a healthy advantage at the interval.
It was one-way traffic in the second half, though, as Jamie Shaul (2), Carlos Tuimavave, Albert Kelly and Danny Washbrook all crossed to leave the Vikings stunned, Marc Sneyd adding four conversions and a drop goal.
Widnes appear destined for a place in the qualifiers, having picked up a paltry five points from 13 games, while Hull are firmly on course for another top-four finish.
