Darts results: Luke Humphries beats Michael van Gerwen to set up Nathan Aspinall showdown

Van Gerwen had impressed in his win over nine-dart hero Josh Rock in the last round, but some wayward finishing during the opening legs saw Humphries, who settled to hit four 180s, lead 3-2 at the interval.

Successive checkouts of 140 and 167 extended Humphries’ advantage at 6-3 before Cool Hand Luke headed into the next break 9-6 in front.

Dutchman van Gerwen, a three-time Grand Slam winner, broke back with an 11-leg dart following the restart only for Humphries to swiftly halt the revival with a 132 checkout.

Humphries’ consistent scoring continued – as did van Gerwen’s poor doubles conversion – to move within one of victory before landing double top to pull it off and eliminate yet another big name from the competition.
