Opener Imran Farhat hit an aggressive half-century and paceman Rana Naved-ul-Hasan took 3-37 to help Pakistan beat the West Indies by seven wickets in the third one-day match in Lahore on Sunday.
The dashing left-hander hit five boundaries and two sixes in his 72-ball 58 to help Pakistan achieve a revised target of 191 with eight deliveries to spare and take an unassailable 2-0 lead in the five-match series.
Pakistan won the second match at Faisalabad by two wickets after the first match was washed out due to rain at Rawalpindi.
Lendl Simmons hit an attractive 70 before bad light stopped play and technical problems with floodlights caused an hour's delay. It forced the West Indies innings to end at 207-7 after 46.3 overs.
The Pakistan Cricket Board said internal faults disrupted the power supply. The home team's target was revised under the Duckworth-Lewis formula to 191 from 35 overs.
Pakistan, without their captain Inzamam-ul-Haq, who injured his left little finger while fielding in the morning, got the start they needed with 64 through Farhat and Mohammad Hafeez (31) by the 13th over.
Off-spinner Chris Gayle dismissed Hafeez and then Kamran Akmal (24) but Farhat was in a rampaging mood, hitting and driving to perfection. He was caught off Corey Collymore with 43 needed off 9.5 overs.
Mohammad Yousuf (28) and Shoaib Malik (21) remained unbeaten when the target was achieved.
