As excited as I was about both Yadav and Aaron playing together, Aaron really needs to handle himself well. He cannot become another Nehra. Injured every 3rd match. On the bright side, despite so many injuries he has not dropped his pace, and if anything has returned even quicker after every injury.
Having said that I look forward to seeing more of them bowling in tandem. SL are a great opposition and have in Sanga and Mahela two of the most experienced and best batsmen playing today. If Yadav and Vaarun Aaron can do well here, it will go a long way towards showing they are ready for the WC.
