Karachi, April 20:

Opener Salman Butt smashed a record-breaking century to help Pakistan beat Bangladesh by 150 runs in the fifth and final day-night international cricket for a 5-0 series whitewash on Saturday.

The left-hander scored a career-best 136 to lift Pakistan to their highest one-day total against Bangladesh of 329-9 before the tourists succumbed to 179 all out in 40.5 overs.

The victory gave Pakistan their 11th successive one-day win, beating the previous sequence of 10 victories achieved between April and November 1990. Australia hold the record of most successive wins, with 21 in 2003.

Bangladesh never looked on course for a consolation win as they were rocked by paceman Mohammad Asif (3-35) who removed opener Junaid Siddique (six), Aftab Ahmed (nought) and Shakib Al Hasan (five) in the space of five balls. In between, Asif’s pace partner Umar Gul had Tamim Iqbal (nine), caught behind by Kamran Akmal to leave Bangladesh reeling at 4-23.

Bangladesh captain Mohammad Ashraful hit four boundaries in his 30 before leg-spinner Shahid Afridi forced an edge which was snapped up by Misbah-ul Haq in the slip. Afridi finished with 3-40. Mahmudullah top-scored with 37 and added 57 for the seventh wicket with Dhiman Ghosh (29) while Abdur Razzak made 33.

Earlier Butt set the tone for Pakistan’s big total. He added a record 179 runs for the second wicket with Younis Khan (69). Butt, whose previous highest one-day score of 132 came in the third match in Lahore on Sunday, hit 14 boundaries and a six during his 124-ball knock.

Shoaib Malik (27) and Misbah (35) added 52 for the sixth wicket before Pakistan lost four wickets in the last five overs. Among those debutant Naumanullah scored just five. Mortaza finished with 4-65.
