Jack Sock has launched a campaign to find the young Wimbledon fan who had Sock’s souvenir towel ripped out of his hands by another spectator on Tuesday.

Sock threw his the towel into the crowd after rounding off his 6-3, 4-6, 7-6, 6-3 first round victory over Chile’s Christian Garin on Court 8.

A young spectator in one of the first few rows caught the towel but then became involved in a tussle for it with an older man in a blue polo shirt sitting in front of him.
