Wouldn't you know it, the next ball Mohammad Rizwan goes for the pull and top-edges the ball away for six.
Penny for Taskin Ahmed's thoughts right now.

Dropped a pretty regulation chance! The keeper almost had both hands to it but the opportunity for an early breakthrough is spilled.
Oh no! Bangladesh have to take those if they are to win this game.
Taskin Ahmed is bowling really well and extracting some life out of this pitch. He gets one to leap off a length to Mohammad Rizwan who edges through to wicketkeeper Nurul Hasan - but he puts the catch down diving to his right.
Babar Azam and Mohammad Rizwan stride out into the middle. Babar has not had a great tournament so far. Now would be the perfect time from a Pakistan perspective to find some form.
Taskin Ahmed will open the bowling for Bangladesh, they will need some early wickets to drag themselves back into this match.
Here we go...
Pakistan cricketer Haris Rauf: "On this wicket I think slower deliveries for a fast bowler and slow balls as a spinner will help you.
On Shakib LBW decision: "If the umpire gave it out, it means its out.
"We have world class openers and because Babar didn't perform well I know in a big match he will try to win the match for us."
Thanks, Callum.
Bangladesh had set themselves a decent platform there, reaching 73-1 near the halfway stage, but Pakistan did superbly well to drag them back.
Pakistan are probably favourites now to chase down 128, but if that Netherlands victory over South Africa tells us anything, it is to expect the unexpected.
Right, then.
The situation is simple:
If Pakistan chase 128 they are through to the semi-finals. If Bangladesh defend 127 they progress instead.
Tom Mallows will take you through the chase.
Here is the controversial moment that Shakib Al Hasan was given out lbw during that Bangladesh innings of 127-8.
The review seemed to suggest he hit it, but the third umpire decided that was bat hitting the ground instead.
What do you think? Out or not out?
Just a bye from the last ball.
Are Pakistan strong favourites to secure a last four spot at the half way point?

Straightforward chance for Wasim and he wasn't going to miss it!
Nasum c Mohammad Wasim b Rauf 7 (Ban 126-8)
Good catch.
Nasum Ahmed goes for the big shot again, but ends up flicking it straight down the throat of Mohammad Wasim on the mid-wicket boundary.
It looks like it takes him by some surprise because he starts to fall backwards but is able to find his balance before he steps on the boundary sponges.
Shot!
Nasum Ahmed backs away and slaps Haris Rauf over mid-off and away to the fence.
Lovely stuff.

There's the boundary Bangladesh were looking for!
A great shot and taking on the pace of Rauf, who is bowling 90mph.
Brings up Afif's 1,000 T20 runs as well.
Four more.
Afif Hossain moves outside his off stump and ramps past short fine leg and the ball faces away to the fence. He just used the extra pace of Haris Rauf.
Can they get up to 130?
Finally a boundary. It feels an absolute age since we last saw one.
Shaheen Shah Afridi goes full, very full, and Afif Hossain guides it between short third and point.
Shaheen finishes with 4-22 from his four overs. He's been very good.

Well bowled from Afridi.
Bangladesh will fall short of what could have been a competitive score.
Taskin c Babar b Shaheen 1 (Ban 109-7)
Pakistan are well and truly bossing this game at the moment.
It's in the slot from Shaheen Shah Afridi but Taskin Ahmed just lobs up a catch to Babar Azam in the covers.
Bangladesh laid a lovely platform, but they have subsided.
Alex Hartley

Pakistan are bowling so well. Pace on delivery, yorkers and Rauf and Afridi still have overs left.
Brilliant over from Haris Rauf. He concedes just two singles from the 18th over.
Bangladesh are going to be well short at this rate.
Poor review.
It's going a fair way down the leg side.
