1.Dimuth 2.Avishka 3.Kusal Perera 4.Kusal Mendis 5.Mathews 6.Pathum Nissanka 7.Thisara 8.Udana 9.Senanayake/Vandersay/De Silva 10.Malinga 11.Chameera/Prasad/Rajitha
The reasons are ,look at other openers, Roy, Baistow,Guptill,Dharwan etc all powerful hitters & you don’t go there just to play the 50 overs.
The only 2 top batsmen in this category for us are Kusal P & Avishka. Mathews come later in the order.Because Dimuth is slow we need someone to hit out & I see only Avishka & Kusal can do it. So give him a chance though still novice.
The reason for Pathum is he looks comfortable facing the spinners which other batsmen find difficult.At least these two will be a future investment even if he fails.
Why Senanayake because he may not be the best spinner but it prolongs our batting strength which is our main problem.All our spinners are not top class so take one with batting ability.
