Kusal, Thisara Perera guide hosts to 5 wicket win over India in the opener of the 2018 Nidahas tri-nation Twenty20 series at the R Premadasa Stadium in Colombo on Tuesday.
Batting first, India posted 174-5 on board before Lanka chased the target in the second innings with nine balls remaining.
Washington Sundar delivered India the perfect start they needed early on by dismissing Kusal Mendis.
But Dinesh Chandimal and co fought back with pride as Danushka Gunathilaka and Kusal Perera soon changed gears and put the hosts in command in a matter of few overs.
Perera was the wrecker-in-chief as he took the attack to the opposition despite losing partners at the other end. The spin duo of Yuzvendra Chahal and Sundar bounced back with a few crucial wickets as the required run-rate kept creeping down.
Sundar soon baffled Perera to get the Men in Blue back in the game. However, what was to follow is something the Indians would not have imagined.
Thisara Perera and Dasun Shanaka played important cameos to steer the hosts to the finish line and shock the tournament favourites.
