Dhaka, Nov. 22 -- Bangladesh are four wickets away from a series sweep over Ireland on the fourth day of the Dhaka Test, with Taijul Islam dominating the attack and surpassing Shakib Al Hasan as the nation's highest Test wicket-taker.

Ireland were 176 for 6 while chasing 509 at stumps at the Sher-e-Bangla Cricket Stadium on Saturday.

Taijul took his 247th wicket to lead Bangladesh's Test bowling charts when he trapped Ireland captain Andy Balbirnie lbw for 13 as the first wicket of the chase in the sixth over.

Paul Stirling, the other opener, also fell to Taijul, caught at short leg where Mahmudul Hasan Joy took a simple catch.

Hasan Murad trapped Cade Carmichael for 19 in the 20th over, and Ireland were 77 for 3 just before tea.
