St Helens (8) 18
Tries: Cross, Dagnall, Sailor Goals: Feldt 3
Leeds Rhinos (0) 4
Tries: Lumb
St Helens took full advantage of a sloppy Leeds Rhinos performance to claim a fully deserved Super League victory.
Kyle Feldt kicked two penalty goals for the home side in the opening 25 minutes before Deon Cross extended Saints' advantage by darting over for the game's first try on the stroke of half-time.
Leeds improved after the break and brought themselves back into the contest when Riley Lumb went over in the corner for his 10th try of the season.
However, a string of handling errors in stifling heat limited the Rhinos' momentum, and tries from Owen Dagnall and Tristan Sailor guaranteed the points for an injury-hit Saints side.
Leeds stay third in the table on 20 points after their first defeat in six, while St Helens are fifth, two points behind.
