Irish Hockey League: Leaders Garvey defeat Monkstown

Lisnagarvey exacted revenge for an earlier 5-2 defeat by Monkstown in Hillsborough to win the rematch and establish themselves as favourites to lift the title and secure an automatic place in Europe next season.
Mikey Watt, who joined the club from Surbiton before Christmas, got the all-important goal in the 40th minute.
The Irish international pounced on a loose ball and drove the ball home from the edge of the circle.

But Mark Tumilty's side dominated most of the remainder of the game and Owen Magee converted his team's sixth penalty corner to reduce the deficit early in the second-half.
Owen's brother Eugene equalised in the final period of the game and then Stevie Dowds converted from the penalty spot to make it 3-2.
Eugene Magee added a fourth goal near the end as Bann avenged their Irish Senior Cup defeat by the Dublin side to stay in the play-off zone, eight points behind Garvey.
