His call-up followed a domestic season in which he had taken the most wickets in the Sri Lankan Premier League limited overs tournament. During the 2013 Indian Premier League auction he was bought by Kolkata Knight Riders for US$15,000. On 2015, he contracted for 2014 NatWest t20 Blast in England for the team Worcestershire.

In March 2018, he was the leading wicke-taker in the 2017–18 Premier Limited Overs Tournament, with seventeen dismissals in eight matches. Later the same month, he was named in Dambulla's squad for the 2017–18 Super Four Provincial Tournament. The following month, he was also named in Dambulla's squad for the 2018 Super Provincial One Day Tournament.

Senanayake made his international debut for Sri Lanka in the fourth One Day International (ODI) of the tour of South Africa in January 2012. From then, he was a regular part of Sri Lanka's spin attack in limited over cricket with Ajantha Mendis and occasionally with Seekkuge Prasanna. After a suspect bowling action, he showed poor bowling in later bilateral tournaments. However, he was included to the 15-men 2015 ICC World Cup tournament as the main spinner of the team.

Bowling action

He was reported for bowling with a suspected illegal bowling action against England in June 2014 and subsequently banned from bowling in international cricket in July 2014. He was cleared to bowl in December 2014 and played in the fifth ODI against England.

In 2014, he Mankaded the English batsman Jos Buttler in a One Day International.^[7]

Remodel action

Senanayake was cleared from the illegal bowling action with future notices and played in the 7-match ODI series against England at home. He was again called up for the 2015 Cricket World Cup and looked poor performances in the pool match against Australia. He re-appeared in the fifth ODI against Pakistan in July 2015, where he took three crucial wickets.

The re-modeling action somewhat gave weaker performances in international arena to Senenayake.
