Luke Humphries kept his cool to defeat Michael van Gerwen 16-10 to reach the semi-finals of the Cazoo Grand Slam of Darts in Wolverhampton.

Van Gerwen had impressed in his win over 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.
