Kieran Dixon scored a hat-trick on his return from injury as Hull KR ran in 10 tries to rout Wakefield Trinity Wildcats 54-16 away from home in Super League.
Having been beaten 38-8 by struggling Salford Red Devils last time out, Thursday's result served as a second successive heavy loss for the Wildcats.
It marked an unhappy reunion for Wildcats coach Chris Chester - who was sacked by Hull KR in February following a defeat to Wakefield.
Victory for the visitors saw interim coach James Webster defeat the club he left in May of last year and at least temporarily moves Hull KR above Salford in the battle to avoid finishing in the bottom four and having to compete with the top four Championship teams for a place in next season's Super League.
Dixon, making his comeback from an injury suffered playing for Newcastle Thunder as part of a dual-registration deal, was the star of the show for Hull KR - scoring the first of five first-half tries as they took a commanding 26-10 lead into half-time.
The winger then added two further scores in the second 40 to complete his treble, with Albert Kelly and James Greenwood also going over twice as Ken Sio kicked seven conversions.
Hull KR are now ninth in the table, three points behind Widnes Vikings, Wakefield stay sixth.
