James Wade and Robert Thornton created history on a dramatic third night at the partypoker.com World Darts Grand Prix in Citywest.
Wade was on the receiving end of a record nine-darter in 2011, when Brendan Dolan hit the perfect leg and became the first to do so in the double-start format.
Last night Wade himself hit a nine-darter against Thornton when starting on 160 before hitting a 180 and checking out 161 on the bull before Thornton himself replied with the perfect leg, ensuring the match was the first to feature both players hitting nine-darters.
At the end of the historic second round game it was Wade who progressed to tomorrow's quarter finals after Thornton missed four darts to win the match.
The night started off with a shock as Kevin Painter came from 2-1 down to knock out Adrian Lewis in the sudden death leg.
Northern Ireland's Mickey Mansell raced into a first set lead against Gary Anderson but the Scot just proved too strong for Mansell and Anderson progressed to the last eight tomorrow night.
Meanwhile, tonight reigning world champion Michael van Gerwen will look to book his place in the quarter-finals when he takes on Dean Winstanley.
The 25-year-old eased through his opening round match against Vincent van der Voort when dropping just one leg and it would prove a huge surprise if he didn't manage to oblige over Winstanley, who conquered Michael Smith here on Tuesday night.
Van Gerwen is likely to be joined in the last eight of the tournament by his Dutch compatriot Raymond van Barneveld who showed his class to come through a tight battle with Dave Chisnall in the first round.
Van Barneveld faces a tough assignment in Mervyn King in the concluding match of the night, but is expected to oblige.
Proceedings get underway with what could be the tie of the night as the high-flying Peter Wright takes on Lakeside champion Stephen Bunting.
