Mahela Jayawardene resigned as Twenty20 captain after Sri Lanka's loss to West Indies in the World Twenty20 final.
Sri Lanka restricted West Indies to 137-6 but then collapsed to 101 all out as they fell to a 36-run defeat in front of their fans in Colombo.
133 matches, 223 innings, 10,540 runs, highest score 374, av'ge 50.43, 31 centuries, 42 fifties, 187 catches
382 matches, 358 innings, 10,772 runs, highest score 144, av'ge 33.34, 15 centuries, 68 fifties, 192 catches
- Twenty20 internationals:
44 matches, 44 innings, 1,224 runs, highest score 100, av'ge 32.21, strike rate 133.77, one century, seven fifties, 14 catches
- Holds the all-time record for most international catches
(combined Tests, ODIs, T20Is) - 393
Jayawardene, 35, who was Sri Lanka's top scorer with 33, said he would still be available for Twenty20 selection.
The batsman also confirmed his commitment to lead the Test and one-day international teams.
"It is not a surprise but I had a chat to the selectors before this tournament started. I was going to step down from T20 captaincy after this World Cup," Jayawardene said.
"I personally feel that for Sri Lanka going forward, I think we need a younger leader. It's a great opportunity for somebody to start in that T20 format."
He led Sri Lanka in 19 Twenty20 matches, winning 12 and losing six with one tied.
The first world title for the West Indies since the 50-over World Cup triumph in 1979 also handed Sri Lanka their fourth defeat in a major final since 2007.
Sri Lanka have now lost two successive 50-over World Cup finals in 2007 and 2011 and two World Twenty20 finals in 2009 and 2012.
Jayawardene said: "I'm very disappointed for the fans we couldn't give them what we wanted but I'm very proud of the boys for the way they played the entire tournament.
"We have been playing some really good cricket but unfortunately we have not been able to cross that hurdle so it hurts, as a player, as a cricketer, as an individual, it hurts a lot.
"We just need to move on, see how well we could get over this, get back on and keep fighting again, that's the most important thing."
