Vaibhav Sooryavanshi (Pic credit: BCCI)Indian teenage sensation Vaibhav Sooryavanshi has etched his name into the record books by registering the fastest fifty in List A cricket history during the Tri-Nation Series final between India A and Sri Lanka A at the Rangiri Dambulla International Stadium.The 15-year-old opener unleashed a breathtaking assault on the Sri Lankan bowlers after Sri Lanka A elected to field first, racing to his half-century in just 11 deliveries, conjuring up a stunning sequence of 4, 4, 4, 6, 6, 0, 6, 4, 4, 6, 6 off his first 11 deliveries. In doing so, Sooryavanshi shattered the previous world record of a 12-ball fifty, set by Sri Lanka's Kaushalya Weeraratne in 2005.Here are the top 5 fastest fifty in list A cricket history:BallsPlayerTeamOpposition/VenueSeason/Year11Vaibhav SooryavanshiIndia ASri Lanka A202612K.
