4. Dimuth Karunaratne
Sri Lanka has been one of the greatest nations which have seen a downfall in their Tets cricket over the period of the last 5 years. However, in 2021, there was one player who walked the talk for the Lankan lions and it was none other than Dimuth Karunaratne. Karunaratne is the third-highest run-scorer in Test cricket in 2021 as he has gone on to score 902 runs in just 7 matches at a staggering average of 69.38.
