MELBOURNE - Australia will trial a modified pink ball featuring a black seam in the domestic Sheffield Shield competition next week after complaints from players about visibility issues during the inaugural day-night test last November. The ball will be used in matches in Brisbane, Adelaide and Perth, and further feedback sought from players, Cricket Australia (CA) said in a statement on Wednesday. "Feedback from the players following the first day-night Shield round, as well as the historic day-night test in Adelaide, is that while the ball had improved significantly, the seam was difficult to see at times," CA's Head of Cricket Operations Sean Cary said.–Reuters
