Which member of a roller derby team is responsible for blocking opposing Jammers?

The role of a blocker in roller derby is crucial, as this player is specifically tasked with preventing the opposing team's jammer from successfully making a scoring pass. Blockers position themselves strategically on the track to form walls and create obstacles that make it challenging for the opposing jammer to navigate through. They employ various techniques such as body positioning, legal physical contact, and communication with teammates to effectively block, redirect, or slow down the jammer's progress.

Blockers also work collaboratively with each other and may assist their own jammer by providing offensive support or shielding them from blocks. This dynamic requires strong skating skills, awareness, and teamwork to ensure both defensive and offensive strategies are effectively executed during a bout.
