Highlights from the latest round of matches in the Super League.The 2017 season has been one of the most unpredictable ever and with just six weeks to go before the competition splits for the Super 8s, it's another crucial set of fixtures. Warrington were the preseason favourites to win the Super League title, but a poor run of form has left them in danger of having to fight for survival in the qualifiers. This week, Warrington face arguably the toughest fixture on the calendar with a trip to Castleford, where the Tigers' sensational home form has been key to keeping them at the top of the table for most of the season. Leigh look for their first home win since the middle of March when they take on local rivals Wigan, and Wakefield face Leeds, with both teams challenging for a top-four finish. In-form Salford are at home to Hull FC, St Helens play Widnes and Catalans are up against Huddersfield.
