Four-wicket over not enough for South Zone
South Zone 343 (Rahman 152*, Mosharraf 5-52) and 216 (Imran 65, Mosharraf 4-68) drew with Central Zone 433 for 9 dec (Ayub 125, Gazi 4-162) and 93 for 6 (Mahmudullah 50*, Islam 5-17)
The match that began with Ziaur Rahman hammering an unbeaten 152 in South Zone's first innings ended with Robiul Islam's four wickets in one over. But the two slow days in the middle, which were also hampered by fog, took too much time out of the game. The match ended in a draw but Central Zone earned two points more than South zone on account of their first innings lead.
Islam removed Asif Ahmed off the second ball of Central Zone's first over, before he clean bowled Mohammad Ashraful, Marshall Ayub and Mehrab Hossain jnr off consecutive deliveries, though he bowled a no-ball before taking the last wicket in the over, depriving him of the hat-trick.
Shamsur Rahman also fell to Islam and immediately Central Zone's chase of 127 runs looked too big. Captain Mahmudullah and Mosharraf Hossain battled for an hour to secure their position. The final day had begun with South Zone's second innings moving towards safety before they collapsed from 71 for 2 to 112 for 7. Tushar Imran and Rubel Hossain added 87 for the eighth wicket to give Central Zone a modest target.
South Zone's first innings was also rescued by their lower-order as they recovered from 192 for 8 to end up on 343 runs. Ziaur's 15 sixes helped him reach a career-best unbeaten 152, with tailenders Rubel and Murad Khan supporting him in valuable partnerships. Central Zone replied well as they took a 90-run lead. Marshall Ayub struck a patient 125, his third first-class century of the season.
North Zone 499 for 6 dec (N Hossain 93, N Islam 82, Baisya 3-63) drew with East Zone 419 for 8 (Ghosh 107*, F Hossain 91)
While there was a lot of excitement in Mirpur, the Bogra game between East Zone and North Zone stuttered all along due to heavy fog in the country's northern parts. Only 244 overs were played after delayed starts on three of the four days. North Zone batted first to make 499 for 6 in two days. They batted only 44.5 overs on the second day before declaring overnight.
Jahurul Islam, Farhad Hossain, Naeem Islam, Nasir Hossain and Farhad Reza all made half-centuries with Nasir getting out in the 90s for the third time this season.
East Zone made 419 for 8 with Dhiman Ghosh scoring an unbeaten hundred. Faisal Hossain, Mominul Haque and captain Alok Kapali also made half-centuries, but it was a game that never had any pace to it and ended in a tame draw due to the weather conditions.
