Champion Van Gerwen stunned in opening round by Gurney in Amsterdam
Defending champion Michael van Gerwen squandered a strong lead to lose 6-5 to Daryl Gurney in the first round of the World Series of Darts Finals, while other seeds progressed smoothly.

The World Series of Darts Finals in Amsterdam produced a shock result as defending champion and Dutch number one Michael van Gerwen was eliminated in round one, beaten 6-5 by Northern Ireland's Daryl Gurney.
Gurney, a late call-up after Lourence Ilagan withdrew from the 32-player field, made a strong start by racing to a 3-0 lead. Van Gerwen hit back with five straight legs, putting himself within touching distance of victory.
But Gurney refused to fold, clawing back the ninth leg. Van Gerwen then missed six match darts, allowing Gurney to level at 5-5 before winning the decisive leg on his own throw.
Gurney advances to Saturday's last 16, where he will face England's Ross Smith, who beat Kevin Doets 6-3 in the previous round.
