Batsman 1 was at strike and batsman 2 was at non-strike end.
As on every ball batsmen were getting out, therefore till the end of over batsman 2 would be at non-strike end.
Batsman 1 on first ball, batsman 3 on second ball, batsman 4 on third ball, batsman 5 on fourth ball, batsman 6 on fifth ball and batsman 7 on sixth ball would be out.
Now, after the end of first over the strike of batsman would be changed.
Batsman 2 would be on strike and batsman 8 would be on non-strike end.
Batsman 2 on first ball, batsman 9 on second ball, batsman 10 on third ball and batsman 11 on fourth ball would be out.
Batsman at number 8 would be not-out.
