Hampshire have signed rising Afghanistan star Mujeeb Ur Rahman and big-hitting New Zealander Colin Munro for this summer’s Vitality Blast.

Teenage mystery spinner Ur Rahman will be available throughout Hampshire’s Twenty20 campaign, and white-ball specialist opener Munro can play for them until he moves on to the Caribbean Premier League in August.

Rahman has been a revelation since making his international debut at the age of just 16 last December, helping Afghanistan qualify for next summer’s World Cup in England and becoming the Indian Premier League’s youngest ever player this year.
