Mensur Suljovic secured a fourth consecutive victory over Michael van Gerwen, continuing his impressive run on Swiss soil and adding to Van Gerwen's nightmare year.
The win marks another disappointing chapter for Van Gerwen, who has struggled throughout the year. Suljovic's triumph extends his personal winning streak against the Dutchman to four matches.
