Carlow created a piece of history today by winning their first ever Leinster hurling championship game defeating London by 4-17 to 2-13 at Dr Cullen Park.
Craig Doyle's hat-trick of goals was vital for the hosts as they held off a spirited London side.
The reigning Christy Ring Cup champions were 1-7 to 0-5 up at the break thanks to Sean Murphy's goal.
Doyle got the first of his goals after the restart and they built up a 10 point lead but the Exiles responded through goals from Martin Duggan and Luke Hands and the gap was just four points with 13 minutes remaining.
Doyle's second and third goals calmed any nerves the home crowd were feeling and even Jack Kavanagh's dismissal for two bookable offences couldn't dampen a famous day for Carlow.
They face the winners of Laois and Antrim in the quarter-final of the Leinster championship.
