During Sehwag's epic triple century at Multan earlier this year, I distinctly remember him going from 99 to 105 with a six over third-man off of Shoaib Akhtar. In fact he did that going from 295 to 301 off of Saqlain Mushtaq.
Tendulkar has also got a century with a 6 in a Test Match. And ironically, it was in the last India-Australia Test match at Chennai in 2001. He hit Colin Miller for a straight six to get to his hundred.
