American Marconi Wireless News - Shanaka fireworks as Sri Lanka thrash Oman at T20 World Cup

The 2014 champions piled up 225-5, the highest total of the tournament, before restricting an outclassed Oman to 120-9.

The 43-year-old Mohammad Nadeem waged a lone battle for Oman, compiling an unbeaten 53 to become the oldest player to score a fifty in T20 World Cups.

Having promoted himself up the order and under pressure to deliver, Sri Lanka skipper Shanaka smashed a 19-ball half-century.

It has been a bruising few months for the out-of-form Shanaka since reclaiming the captaincy late last year.

But on a batting-friendly pitch he smacked the Oman bowlers to all corners of the park, peppering the stands with five sixes and two fours.

Before that, Pavan Rathnayake and Kusal Mendis laid the foundation as the pair each posted fluent half-centuries, stitching together a 94-run stand for the third wicket.

Once the platform was set, Kamindu Mendis applied the finishing touches.

Fresh from his match-turning cameo in the win over Ireland, the left-hander scored an unbeaten 19 off just seven deliveries, striking one four and two sixes.

Oman were never really in the game as they fell to a second defeat at the tournament.

Sri Lanka spinner Maheesh Theekshana shared the new ball with Dushmantha Chameera and they accounted for two wickets apiece.
