Keaney struck 1-03 as Val Andrews' side got the better of Ulster to set up a decider against Connacht in Boston.

Cavan's Seanie Johnston and Tyrone hitman Stephen O'Neill both netted in the first half for Ulster, as the sides went in at the break level at 2-04 to 1-07.

A penalty from Meath forward Joe Sheridan handed Leinster their first goal, and a four-point spurt in the early stages of the second half raced them into the lead.

Johnston, who found the net in the third-minute, took his personal tally to 1-05 during the second period but a neatly taken green flag from Keaney rounded off the visitors' win.
