Keaton Jennings, born in South Africa and having captained their Under-19s as well, scored a century for England in his first innings as a Test cricketer. Twitter reacted in celebration and some regret as well

Out came the references to his birthplace.

Some love from his Durham colleagues

It wasn't just his county team-mates who were impressed.

Some remembered Keaton's father and coach, Ray Jennings, who missed out on international cricket due to South Africa's years of sporting isolation.
