Sri Lanka made a triumphant return to Lahore on Saturday to record of their best T20I wins by hammering top-ranked side Pakistan at their own backyard. An all-round display from the young team resulted in a 64-run win. It will help set up the three-match series beautifully with both the remaining encounters happening here, where the visitors faced a horrific terror attack in 2006. Put into bat, Lankans got off to a flier with Danushka Gunathilaka (57) and Avishka Fernando (33) putting together 84 runs inside the 10 overs. But 19-year-old Mohammad Hasnain took a hat-trick Lankans failed to make the most out of the start. Bhanuka Rajapaksa contributed with 32 runs. Visiting captain Dasun Shanaka used five bowlers, and all of them -- Kasun Rajitha, Nuwan Pradeep, Isuru Udana, Wanindu Hasaranga and Lakshan Sandakan did their job. Iftikhar Ahmed top-scored for the hosts with 24-ball 25. Skipper Sarfaraz Ahmed made 24 off 30. No other batsmen except Babar Azam managed to reach the double figures.
