Sri Lanka were far from perfect after yet another batting collapse against Afghanistan, but all-rounder Thisara Perera said the team always had faith in their "experienced bowling unit" to pull off the win.

After being put into bat, Sri Lanka could only manage to put 201 on the scoreboard before Nuwan Pradeep (4/31) and Lasith Malinga (3/39) starred with the ball to bundle out Afghanistan for 152.
