SUBSTITUTES John Sharkey David Ward killed off the challenge of Boyne Harps, nabbing three late goals between them to book a place in the Kilmessan Shield Final for the Premier Division leaders.
Rock had the measure of the joint first division pacesetters at Sandy Lane on Friday night, but only held a slender 1-0 lead at the break as they failed to make a liberal supply of scoring opportunities count. Boyne also had a number of chances, including one notable one that Paddy Reilly did very well to thwart as a visiting player got away from him and into the home box in the closing minutes.
Kevin McArdle, courtesy of great work by assistant manager David Hoey, gave Rock the lead, which Paddy Quinn made more comfortable when he was sent clear down the left to cut inside the box to score with a clinical finish through the goalkeeper's legs from a tight angle.
However, it wasn't until the introduction of Sharkey and Ward that Rock put the issue beyond doubt. The former tucked away the breaking ball from close range after an excellent move started down the left ended with fellow substitute Ward crossing low from the endline on the right.
Ward then finished the tie with a brace of his own, both finely fashioned and smartly taken. On the first occasion he was sent racing clear down the right and veered inside into the box and struck a pinpoint angled shot into the bottom far corner of the net.
His second and side's fifth goal was coolly crafted by partner Quinn and McArdle for the latter to roll the ball across the 18-yard box for Ward to stroke it low inside the near post, again giving the goalkeeper no chance.
