A solitary try from Sam Powell proved enough for Wigan Warriors as they edged out Castleford Tigers 6-4 in an error-strewn Super League contest at the DW Stadium.
On his return from a two-match suspension, Powell powered through a weak tackle from Tigers full-back Peter Mata'utia to touch down 13 minutes into the second half.
Zak Hardaker duly converted against his former club and that rounded off the scoring, with Castleford's only points having come courtesy of two Mata'utia penalties in the first period.
After an abysmal start to the campaign, defending champions Wigan are now up to eighth courtesy of their second win in six days, while Castleford remain fourth but have lost three of their last four fixtures.
In Saturday's other game, Niall Evalds became Salford Red Devils' most prolific try-scorer in Super League, registering his 66th four-pointer for the club in a 30-10 victory at London Broncos to move clear of previous record-holder Stuart Littler.
Evalds was one four men to touch down in the first half as Salford racked up 24 unanswered points and left the Broncos with far too much to do.
The Red Devils remain seventh, while the Broncos' sixth successive defeat - following an impressive start to the campaign - means they remain rooted to the bottom of the table.
