Crotty closes it out for Déise
Tom McGlinchey praised Waterford's resolve following a second straight league victory under the lights at WIT.
Wicklow whittled down a seven-point gap to just two early in the second-half, but the league leaders re-established their dominance.
"The players showed great composure," said McGlinchey. "I'm delighted with how they finished it out."
Four points on the bounce from Brian Looby, Patrick Hurney, Paul Whyte and Donie Breathnach stabilised the home team. Substitute Gavin Crotty netted for the second week running to close it out.
