Final answer:
Sir Garfield Sobers established the world's first specialist cricket academy in 1970, contributing to the professionalization of cricket talent development.
Step-by-step explanation:
The world's first specialist cricket academy was created by Sir Garfield Sobers in 1970. Neither Sir Don Bradman in 1930, Ricky Ponting in 2000, nor Shane Warne in 1995 are credited with this particular achievement.
Sir Garfield Sobers, a legendary all-rounder from Barbados who is widely considered one of the greatest cricket players of all time, took the initiative to establish an institution focused on nurturing and developing cricket talent, long before such academies became a common feature in the sport. This move helped professionalize cricket training and provided a pathway for young cricketers to develop their skills under the guidance of experienced coaches and players.
