Karthik Meiyappan's historic hat-trick was in vain as Sri Lanka thrashed the United Arab Emirates by 79 runs after Netherlands moved to the brink of the T20 World Cup Super 12s.

Sri Lanka suffered a shock defeat to Namibia in the first game of the tournament on Sunday, but responded with an emphatic win over UAE at Kardinia Park.

Pathum Nissanka top scored with 74 from 60 balls as the Asia Cup champions posted 152-8, Meiyappan (3-19) becoming the first UAE player to take a T20I hat-trick.

Sri Lanka had been 117-2 in the 15th over, but a late collapse did not prove to be costly as UAE were skittled out for only 73 in 17.1 overs.

Wanindu Hasaranga claimed brilliant figures of 3-8 from four overs, while Dushmantha Chameera (3-15) and Maheesh Theekshana (2-15) also sparkled under the lights to leave Sri Lanka in third place in Group A, level on points with Namibia with an inferior net run-rate.

The Netherlands are two points clear at the top of the group after bringing Namibia back down to earth with a five-wicket victory.

Namibia posted 121-6 and the Dutch got home with three balls to spare, Bas de Leede named man of the match after making an unbeaten 30 and taking two wickets.
