Hurling: London 3-11 Derry 1-15
Having seen his side book a semi-final appearance against Down, London manager Eamonn Phelan was jubilant.
"The biggest day in London's hurling history," was how he described it.
Three first-half goals proved enough for London as they withstood a Derry comeback at Celtic Park on Saturday.
The Exiles looked to be on their way to a comfortable win thanks to two goals from Luke Hand and a Martin Finn strike.
Yet, having built a 3-9 to 0-6 half-time lead, it was a case of hanging on as the home side outscored Phelan's men 1-9 to 0-2 after the break, with Paddy Henry taking the Derry goal.
