Carlow started brightly and with Darragh Foley dominating at midfield they built up a handsome 0-5 to 0-1 lead by the 22nd minute.
Ominously for them Foley was their main scoring threat and when Wexford’s Brendan Halpin was upended in the square in the 29th minute Conor Carty buried the penalty to give his side a 1-4 to 0-5 interval lead.
Two points from Emmet Kent and one each by Conor Carty and Kevin O’Grady, stretched the Wexford lead to seven points in the second-half.
Carlow produced a late rally as Foley notched three points from frees to narrow the gap to four points with six minutes left to play.
However, Kent popped up to ease Wexford nerves and ease the Model County into the decider in two weeks time.
