During certain types of dismissals (caught, run-out and obstructing the field), the on-strike batsman after the dismissal is determined based on the position of the not-out batsman on the pitch.
- If they were taking a run and the not-out batsman had crossed their partner when the catch was taken or the run out occurred then the not-out batsman would have to switch ends.
- On the other hand if the not-out batsman hadn't crossed the middle of the pitch he would have to continue on the same end.
A few examples to understand the same:
- If the batsman on-strike is caught behind and the non-strike batsman hasn't left his crease then the new batsman in takes strike.
- If the batsman on-strike is caught while taking a single and the batsmen have completed a run meanwhile then the not-out batsman takes strike because he has crossed.
- If the batsman on-strike is run-out while completing his second run, the new batsman in takes strike because the not-out batsman is back to his original end.
These rules are described in detail in Law 18 (Section 11 & 12).
