And he was NOT.
Even the commentator picked two possibility- Yorker or bouncer?
Hitting 6 brings two things- for the batsman he attempts another big shot (and mostly have the consequence of Ash!) and for the Bowler, he want to take a revenge and delivers a better ball with variation.
Ashraful did not know this and failed to dig down the yorker.
If he could score a30 even, our chances would be better.
