England opener Jos Buttler on Monday said it was tough to get going initially before completing his maiden international century in the shortest format as he set up his side`s 26-run win over Sri Lanka in a T20 World Cup match here. Buttler`s 101 not out off 67 balls proved to be the difference as England posted 163 for 4 after being put into bat and then bowled Sri Lanka out for 137 in 19 overs to register their fourth win on the trot and virtually seal a semifinal spot. "I think staying patient and keeping my head. I found it really tough early on. I managed to get a really good partnership going with Morgs (Eoin Morgan) and we tried to attack the back end," Buttler said at the post-match presentation. "We were just trying to get something going, were finding the spin bowlers a bit tricky and thought 120 might be a good score. We each tried to take the small side and target that and I really enjoyed batting with Morgs."

Buttler took 45 balls to reach to his half century and then needed just 22 deliveries for the remaining 50 runs. "I just use the same (bat) all the time. Even in the nets, if I find one I like, I keep it," he said about his bat. Asked about the final ball six which took him to his maiden T20I ton, Buttler said, "I was trying to guess where he was going to bowl to be honest. I was pretty calm. But I think at that stage I`d batted for a long time, just staying patient and hoping he (the bowler) will miss." Buttler also effected the run-out of Sri Lanka captain Dasun Shanaka with a direct throw in the 18th over of the islanders` run chase, and he described it as a "favourite" moment. "(The run out) was probably the favourite bit of my day. We were under pressure there for a long part of that chase knowing that (Moeen Ali) had to bowl that (missing over after Tymal Mills left injured), so to take that wicket there was crucial and I was delighted with that." England captain Morgan said he was incredibly proud of his players for the win.
