Paddy Henry late show helps Derry see off the London
Derry 1-12 London 2-08
Derry's hurlers claimed a place in the last four of the Christy Ring Cup for the first time since 2008 with a last gasp win over London at Owenbeg.
Extra-time looked on the cards with the sides tied in injury-time, but a late '65' from man of the match Paddy Henry secured a 1-12 to 2-8 win for the Oak Leaf men.
Henry was also the Derry goal hero, firing the sliotar to the net on 38 minutes after a superb ball from Alan Grant, while Mark O'Dwyer scored both goals for the Exiles.
London started with more purpose and led by 0-4 to 0-0 after 12 minutes, with Peter Phelan on the mark from frees and Michael Ivors with the pick of the scores from play.
In the driving rain, Derry finally got into gear and opened their account through Paul Cleary and with two Ruairi Convery frees and a Paddy McCloskey effort, Derry were back on terms by the 22nd minute.
Two Henry points put Derry one ahead after Phelan had restored London's advantage.
But the home side were dealt a blow when O'Dwyer touched a long delivery to the net in first half injury time to give London a two-point lead - 1-5 to 0-6 - at the short whistle.
Derry hit the ground running in the second half and an unanswered 1-2 had them 1-8 to 1-5 ahead on 42 minutes.
The sides went score for score until just after the hour mark with Phelan and Henry accounting for the bulk of the scores from frees, but when O'Dwyer pounced for his second major on 61 minutes, the sides were all square at 1-10 to 2-7.
Niall Ferris put Derry one ahead with three minutes on the clock but a Phelan free levelled the sides for the sixth time, and with extra time looming, Henry converted a '65' deep in injury time to put Derry into the last four.
They join favourites Kerry in the semi-finals and now await the winners of Saturday's quarter-finals.
London use up their 'back door' chance against Down, with Meath and Kildare clashing in the other quarter-final as the tournament builds towards a climax.
