Derbyshire have signed Nantie Hayward, the former South Africa quick, until the end of the season to strengthen their seam attack after losing Charl Langeveldt to injury.His arrival is subject to obtaining a visa, but head of cricket John Morris said it was important to bolster the fast-bowling resources. “After the disappointment of losing Charl Langeveldt for the season, it was very important that we brought in somebody to strengthen our bowling department.”Although we have got some great young talent and some fine bowlers already at the club, there is a lot of cricket to be played this year and a squad of bowlers is always needed.”With that in mind, to be able to get somebody of Nantie’s experience at such short notice is a timely boost for the team.”Hayward, who has 431 first-class wickets, has had previous county spells with Hampshire, Middlesex and Worcestershire.
