Lisburn's Andrew Marshall birdied the 18th to force a three-hole playoff which he won by three shots to lift the Leinster Boys Amateur Open at Headfort.

Two strokes behind Mallow's Edward Walsh and Castle's Robert Moran with a round to play, Marshall birdied the last on the New Course to card a two-under-par 70 and match Walsh (72) on one-under-par 215, one stroke ahead of Laytown and Bettystown's Alex Maguire, who won the Under 17 title.

In the three-hole aggregate playoff over the par-four 10th, eighth and ninth holes, Marshall went par-par-birdie to bogey-par-bogey figures by Walsh to win by three shots.

Dundalk's Eoin Murphy shot a 70 and Hilton Templepatrick's Reece Black a best-of-the-day 68 to leave them tied fourth, three shots outside the playoff on 218.
