St Helens have been gradually improving under Justin Holbrook and should have enough about them to see off Catalan on Sunday.
Saints defeated Hull last weekend, while the Dragons were defeated at home to Wigan.
Catalan lost the reverse fixture 28-24, although they have won four of their last six meetings with St Helens.
Betfred are offering 9/2 for an 11-15 point winning margin for Saints and 5/1 to triumph by 16-20 points. Covering both could return a decent profit.
