The umpire has given a leg bye, it looked like it came straight off the bat.
But maybe I couldn't see through the air...
A little bit of bounce for Shoriful Islam first up, but it is on the pads and Sri Lanka get up and running with a leg bye.
The national anthems are done. Bangladesh are out in the middle ready and the Sri Lanka openers are making their way out.
Time for cricket.

Sri Lanka have been a little bit unlucky in a couple of games when they've come quite close.
They've had the difficult game against India - but who hasn't had a difficult game against India?

Bangladesh have really not settled on a batting line-up. Mehidy Hasan Miraz, for example, has batted in five different positions in the last six matches.
I think they will look to settle that order and play people in their preferred positions.
As for the bowling, Tanzim Hasan coming in for his World Cup first match is an interesting one. Bangladesh are just trialling their options because their bowlers haven't quite fired as they'd have hoped.
Both of these sides lost their previous game.
Bangladesh were humbled by a rampant Pakistan, and Sri Lanka were swept aside by India in being bowled out for just 55.
Have a watch of the highlights.
Bangladesh: Liton Das, Tanzid Hasan, Najmul Hossain Shanto, Shakib Al Hasan (c), Mushfiqur Rahim (wk), Mahmudullah, Towhid Hridoy, Mehidy Hasan, Taskin Ahmed, Shoriful Islam, Tanzim Hasan.
Sri Lanka: Pathum Nissanka, Kusal Perera, Kusal Mendis (capt & wk), Sadeera Samarawickrama. Charith Asalanka, Angelo Mathews, Dhananjaya de Silva, Maheesh Theekshana, Dushmantha Chameera, Kasun Rajitha, Dilshan Madushanka.
Sri Lanka captain Kusal Mendis: "The wicket looks very good, I'm OK with batting first. It is a chance for our batting unit to put a good score on the board.
"We need 300-plus on this wicket."
Bangladesh captain Shakib Al Hasan: "It looks a very good wicket, as we've seen in other games. There have been lots of runs but we think it will be difficult to bowl at night because there's been a lot of dew in the evening in our training sessions.
"We're not taking much home with us at the moment. There's a lot of expectations but we haven't been able to fulfil them yet. Hopefully we can in the last two games.
"We have to be technically sound and mentally strong to be able to compete in this kind of competition."
The game is going ahead though and the toss took place a short while ago.
Kusal Mendis called incorrectly and Bangladesh captain Shakib Al Hasan fancies a bowl first.
This match in Delhi has been in doubt over the past few days because of the air quality in the Indian capital.
Both sides have had to cancel training sessions, while schools have been closed and are set to be all week with the air quality listed as "severe".
The International Cricket Council and Board of Control for Cricket in India say they have completed work at the stadium to make it as safe as possible for the two sides.
A statement said: “The BCCI engaged the services of renowned Pulmonologist Dr Randeep Guleria to assess the situation in Delhi ahead of Monday’s game and provide independent expert advice.
"Under Dr Guleria’s guidance, the venue team has been taking mitigating actions throughout the day including the implementation of water sprinklers around the premises and the installation of air purifiers in the dressing rooms and match officials areas.
"The AQI within the stadium was monitored throughout the day which has reduced to levels considered acceptable by Dr Guleria."
According to IQAir, external Delhi is the most polluted major city in the world at the moment, with a score of 251 meaning "very unhealthy". London is 21 in comparison.
Bangladesh are out.
Sri Lanka are just about hanging on, but realistically are also out.
However, there's still something to play for in Delhi.
A win for Sri Lanka in particular would go a long way to securing a place at the 2025 Champions Trophy in Pakistan.
Let's get to it.
