'Keaton is my hero!'

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

Wonderfully batted @JetJennings. Looked the best opener on the tour for the tourists.

He was the best batsman we played against last season & it's great to see @JetJennings continuing his fine form on debut @englandcricket

What an amazing achievement from @JetJennings! That is what you call grabbing your opportunity with both hands ! Well deserved #INDvENG

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

What must Ray Jennings be feeling - a man denied Test cricket by South Africa's exclusion - seeing son make 100 on Test debut? #tearsofjoy
