First-half goals set up Wexford win
The hosts raced 1-2 to 0-1 clear following a 13th minute goal from PJ Banville.
Points from Raymond Galligan and Eugene Keating kept Cavan in touch before Ciarán Lyng converted a Wexford penalty. Cavan keeper James Reilly then dropped a high Ben Brosnan effort and Eric Bradley tapped the ball into an empty net.
