Challenge Cup: St Helens, Hull KR and Salford Red Devils through to last eight
The Saints started the season with a win a week ago, struggling with Hull KR a week ago, but their offensive performance after intervals could alleviate some concerns due to the vulnerability of some of their games.
Feldt’s attempt came from a clever kick, and the Mariners supported their game assists to get a pass from Harry Robertson to score, and then played a perfect kick that Leeds failed to deal with to return to favour.
Whitley also ran off to off-road from George Delaney and Strong of Jonny Lomax.
Leeds failed to score against Catalonians last weekend, and Brad Arthur’s team lacked liquidity and executions to end some great situations.
Their two scores are saints who are clear on the scoreboard and they fail to find the extra gear they need.
