Mahmudullah Riyad scored a Test career-best 150 not out on Thursday as Bangladesh made 468 in the first innings of a one-off Test against Zimbabwe at Harare Sports Club.

In reply, Zimbabwe were 114-1 at the close of play on the second day with opening bat Milton Shumba making 41 and captain Brendan Taylor unbeaten on 37. Batting at number eight, 35-year-old Mahmudullah added 96 runs to his overnight 54 as the tourists took control after losing two early wickets on Wednesday with just eight runs on the scoreboard.
