Gavin Dodd scored 22 points to help Swinton to a 38-12 victory over Hunslet at the South Leeds Stadium.
John Oakes' first-half try gave the Hawks hope of a second win of the season but former Warrington winger Kevin Penny's try just before half-time proved crucial and Martin Ainscough scored his second try in the second half to make sure of the Lions' third victory.
Hunslet's Joe McLocklan managed a consolation try two minutes from the end but there was still time for Dodd to complete his hat-trick, to go with his five goals.
