Dasun Shanaka scored the fastest half-century by a Sri Lankan in men's T20I cricket, to lead his team to a comfortable 105-run win over Oman in the 2026 T20 World Cup. Shanaka, who is also captain of the team, hit five sixes and two fours to reach 50 runs facing just 19 deliveries, bettering the 20-ball record that he previously held against India in January 2023. Sri Lanka ended their innings on 225 for the loss of 5 wickets, with their bowlers rallying to restrict Oman to 120 for 9 in their 20 overs, giving the co-hosts their second win from as many matches in the tournament. Shanaka's innings Shanaka was under pressure coming into this game, having been dismissed for a first-ball duck (zero runs) in Sri Lanka's opening game of the tournament against Ireland. That put him at the top of the list for an unwanted record for the most ducks in men’s T20I cricket. When Shanaka walked out to bat, in the 14th over of the innings, Sri Lanka were strongly placed on 136 for 3, thanks to a 94-run third-wicket partnership between Kusal Mendis (61 not out) and Pavan Rathnayake (60). Shanaka promptly capitalised, pushing Sri Lanka’s total to 199 before being dismissed for 50 in the 18th over. His half-century also eclipsed the record for the fastest half-century by a Sri Lankan at a men’s T20 World Cup, when Mahela Jayawardena scored 50 off 21 balls against Kenya in 2007. The record for the fastest fifty in a T20 World Cup is currently held by Yuvraj Singh, who scored a 12-ball half-century against England also at the 2007 tournament. Top of the table With wins in both their World Cup matches so far, Sri Lanka are currently top of Group B with four points, ahead of Australia who have featured once so far in the tournament when they beat Ireland by 67 runs. That gave the Aussies a net run rate of 3.350, which would put them back on top of the points table if they beat Zimbabwe in their next match. Net run rate is the average runs per over a team scores minus the average runs per over conceded during the round-robin stage of a tournament. It is used as a tie-breaker to determine group standings and qualification for the next round.
