The appointment by Centric Sports follows the England team's historic success at the World Twenty20 last weekend.
Pitch will be responsible for delivering proactive PR campaigns for each player as they seek to manage their reputations in a massive year for English cricket.
The agency will look to generate publicity opportunities in sports, news, lifestyle, business, regional print and broadcast press for each player, as well as working closely with current sponsors of Broad, Anderson, Wright and Prior and developing new commercial partnerships.
Pitch chief executive Henry Chappell said: 'Cricketers have long lived in the shadow of their footballing counterparts in terms of commercial deals. But with the team winning its first world title in the West Indies and an Ashes tour on the horizon, interest in players such as Broad, Anderson, Wright and Prior will be higher than ever before.'
