Cassell excited to be associated with RR
Cassell, who is said to make his IPL debut as a coach said, "I am really excited at the prospect of working with the Rajasthan Royals during this year's Indian Premier League. The Royals have a great fast bowling set-up with a good mix of Indian and foreign pacers, all of whom bring a lot of quality and potential."
I have been following the Royals from afar, says Cassell
"I have been following the Royals from afar for quite some time, and I think this is a dynamic, exciting and highly competitive fast-bowling line up. I am therefore really excited to chip in with my ideas and help maximize this team's abilities," he added.
