India batsman Sachin Tendulkar has achieved his 50 century in Test cricket, reaching 107 not out on Sunday, on the fourth day of the first Test against South Africa in Centurion.
Tendulkar, 37, dedicated the innings to his late father, Ramesh, whose birthday was on Saturday.
No other batsman has made more than 39 Test centuries, but India are facing a big loss despite Tendulkar's milestone.
With one day to play they are 454 for 8 in their second innings, 30 runs behind South Africa's first innings total.
Tendulkar started his test career 21 years ago with two half-centuries against a Pakistan bowling attack that included Imran Khan, Waqar Younis and Wasim Akram.
He has also hit a record 46 centuries in one-day internationals.
"Every innings I play, I go out to score runs," he said. "It's extremely important to have that hunger. The hunger keeps one going and I'm glad that it's still there."
