Lahiru Kumara might not be the highest wicket-taker for Sri Lanka in 2018 but he was their best pacer. In just six matches, he has 26 wickets to his name, a record much better than the other Sri Lankan pacer Suranga Lakmal's (31 wickets in 12 matches.)

Of the 1241 deliveries that he bowled in 2018, 3.50% were above 145 kmph and 67 % were in the range of 135-145 kmph. His best performance with the ball was against the West Indies at Port of Spain in which he picked up 7 wickets. In spite of him picking up four and three wickets in the first and second innings, Sri Lanka lost the match as the batsmen let down the team.
