he is the scorer of fastest test century of all time..he held the record for most runs in a calender year until mohamad yusuf broke it name him?

Viv Richards held the record for the fastest Test century for many years, scoring 100 runs off just 56 balls against England in Antigua in 1986. This record stood until 2002 when it was broken by Nathan Astle (off 54 balls), then Misbah-ul-Haq (off 56 balls), and subsequently others. Richards also held the record for most Test runs in a calendar year (1,710 runs in 1976) until Mohammad Yousuf broke it in 2006. His aggressive batting and dominance made him one of cricket's most destructive batsmen.
