Worsfold, almost single handedly at times, prevented Sussex from running completely riot. She blocked well at the feet of Hayley Bridge and then flung herself low to tip a Jaime Quinn effort around the post.
To their credit, the Navy plugged away and pulled a goal from the penalty spot through Anthea Kaptein, who dusted herself down to score a consolation having been felled by Michelle Ward.
Cole fired wide and Ava Rowbotham headed off the line from home captain Natalie Bavister as it was all hands to the pumps for Sussex in the closing stages.
Despite their spirited second-half showing, the Navy were unable to turn the tide as Sussex held firm in the face of belated pressure.
Sussex now sit atop the four-team group in the Cup, and coach Hayes was pleased with the result and in particular his side’s performance. He said: “We played very well in the first half, second half they came out and put us under pressure but we coped well with that, there were a lot of niggly moments which disrupted us and the flow of the game.
“Jess Burke had a very good game at full-back, not her natural position, and I’m pleased that the team have gelled, as a collective we’re looking strong despite not being together long, a new, young group of players from different corners of the county can be difficult to mould into a cohesive side but we’ve managed to do that so far.
“A good win, we’ve got a home game next up with Jersey in the New Year, we’ve built up form and momentum so it’s important to keep that going now.”
