DRS in cricket explained: how the Decision Review System works, what ball-tracking and UltraEdge show, and why teams use their reviews carefully.
You have seen players signal a "T" and the big screen light up — but how does it actually work? Here is DRS in cricket explained, in simple terms, so you understand every review.
DRS in cricket stands for the Decision Review System. It lets teams challenge an on-field umpire's decision using technology, so clear mistakes can be corrected.
Each team gets a limited number of reviews per innings. If the review is successful, they keep it; if not, they lose one. That is why captains think hard before using DRS in cricket.
For marginal LBWs, "umpire's call" means the on-field decision stands — a concept that causes plenty of debate among fans.
