An inexperienced Sri Lanka upset top-ranked Pakistan with a 64-run victory in their first Twenty20 cricket match on Saturday.
Eighth-ranked Sri Lanka scored 165-5 before dismissing hosts Pakistan for 101.
Sri Lanka was pulled back by 19-year-old Pakistan fast bowler Mohammad Hasnain (3-37), who grabbed a hat trick over separate overs in only his second T20 international.
He is the second bowler to achieve the feat in the shortest format of the game. Hasnain first dismissed Bhanuka Rajapaksa and then it was the turn of skipper Dasun Shanaka to go back. Shehan Jayasuriya gave a simple catch to Shehzad to help Hasnain in becoming the youngest bowler to take a hat-trick in T20 internationals.
