Has any retired cricketer's son won a medal in the Tokyo Olympics?

 Every athlete dreams of winning a medal in Olympics but it is not that easy, not everyone can win medals in Olympics and it becomes more hard if your sport is not part of the grandest stage of the sports, Cricket has its origins from 16th century and it became a national sport of England in 18th century and yet it is not part of the Olympics.

Cricket was part of 1900 Olympics and only Great Britain and France competed against each other, however later it was removed after that year because of lack of participation from other countries, but it didn't stopped few cricketers or their family members from participating in the Olympics.

Rai Benjamin

Although Rai Benjamin isn't directly involved in cricket, but his father Winston Benjamin might be a familiar name to many cricketers and many cricket fans.

Winston, played for West Indies team in 21 tests and 85 one-dayers, he played his last ODI against England in 1995 after having a career with the national side that revolved for nine years. Recently, his son Rai has won a silver medal in the men’s 400m hurdles at Tokyo 2020 Olympics.

Brandon Starc

Even if you are not able to recognize this Australian high jumper you will notice the last name, it's quite familiar right? and I would say yes you are correct he is indeed related to Aussie pace bowler Mitchell Starc.

Brandon is brother of Mitchell Starc who recently participated in Tokyo Olympics in men's high jump category, he made into the finals of the event but finished fifth.

Bad luck mate, but there is always a next time.
