Kildare, Derry, London and Wicklow all progressed to the Christy Ring Cup semi-finals, while Armagh and Mayo's relegation was confirmed.
The Lilywhites outgunned Wicklow 4-19 to 3-18 in Aughrim with goals coming from Jack Sheridan and Martin Fitzgerald, who bagged two apiece.
Both teams go on to the last four however, with Kildare paired against Derry.
Colm McGurk's men squeezed through in incredible fashion, as a last-minute Cormac O'Doherty '65' gave them a 1-29 to 2-19 win against Down in Ballinacreen and saw Derry go forward on points difference.
With three teams locked on four points, it came down to scoring difference to separate London (+28), Derry (+24) and Down (+23).
Down lost out, as London thumped Armagh 4-27 to 0-11 and topped Group 2.
