After an impressive opening, Amanda Walker broke the deadlock from a penalty corner in the 20th minute. The goal galvanised Genesis who enjoyed their best period of pressure leading into the break but were held at bay.
The reds doubled their advantage a quarter of an hour into the second half through Sarah-Jane Ross and they kept the lead intact despite Genesis twice having the ball in the net. Both were disallowed, though, while Holly Warren went close to making it 3-0 late on but saw her effort come back off the post.
It means the status quo remains with Genesis remaining in division two while Corinthian will ply their trade in division one for another season.
