Sent into bat, only three Afghan batsmen managed double digit scores as India, who surprisingly fielded an unchanged squad for dead rubber, rode on the exploits of Jadeja (4/30) and Ashwin (3/31) to bowl out their less-formidable opponents in 45.2 overs at the Sher-e-Bangla National Cricket Stadium.
After pacer Mohammed Shami gave India the first breakthrough in the form of Nawroj Mangal, it was a one-way traffic as Jadeja ripped apart the inexperienced Afghan batting line-up with his left-arm spinners in offie Ashwin's company.
Shenwari's rearguard knock helped Afghanistan cross the 150-run mark, especially they were reduced to 95 for seven at one stage.
Shenwari shared 26 runs with No 10 batsman Shapoor Zadran and 22 for the last wicket with Dawlat Zadran to bring up his fifth ODI half-century and second in the tournament.
Apart from Shenwari only two others -- Noor Ali Zadran (31) and Mohammad Shahzad (22) -- could reach double figures in front of India's hostile spin attack.
