In a stunning display of tactical innovation, England's Sam Curran has been leaving batters in a spin with his ultra-slow 'moon ball' delivery. But what exactly is this enigmatic delivery, and how has Curran mastered it? Sam Curran, a left-arm fast bowler, has been a key member of the England cricket team since his debut in 2017. The 27-year-old has already achieved numerous milestones, including taking a five-wicket haul in his first Test match and being named the ICC Emerging Player of the Year in 2018. His impressive record in the One-Day Internationals (ODIs) boasts an average of 25.93 and a strike rate of 28.1, with over 120 wickets to his name. England's team has been making steady progress in the ongoing ODI series against Sri Lanka, with several standout performances from the squad. The team's strong batting lineup, led by the likes of a few key players, has been instrumental in securing crucial wins, while the bowling unit has been equally impressive, with several bowlers chipping in with vital wickets. With the team looking to seal the series, Curran's moon ball delivery has added a new dimension to their attack, leaving the opposition perplexed.
