Najmul Hossain Shanto and Shadman Islam both struck hundreds on Saturday as Bangladesh turned the screw on Zimbabwe on the fourth day of the one-off Test at the Harare Sports Club.
Opener Shadman made a steady 115 not out while Najmul was bolder with his unbeaten 117 but it was home captain Brendan Taylor who produced the day's most astonishing innings with 92 from 73 balls as Zimbabwe went in search of a monumental and highly unlikely victory target of 477.
Zimbabwe had reached 170-3 at the close, still 337 short of what would be a record-breaking target, leaving Bangladesh strongly placed to close out victory on Sunday. The West Indies hold the world record for a successful fourth-innings chase, reaching a 418-run target set by visiting Australia 18 years ago.
