About Roster Checker

Stop the roster squatting and keep your league fair. Manually checking every team in your fantasy baseball league for illegal roster placements is a chore. Roster Checker does the heavy lifting for you, scanning your CBS Sports league page to ensure every player is exactly where they belong. Key Features: The IL Watchdog: Instantly flags players sitting in an Injured roster slot who are not actually on the official Injured List (IL). The Prospect Patrol: Automatically identifies players in "Minors" slots who have exceeded your league's eligibility thresholds. Fully Configurable: * Toggle Injured and Minors checks on or off independently. Customize career stat thresholds (Default: 130 AB for hitters, 50 IP for pitchers). One-Click Reporting: Run the check and get a clean, organized report of all violations grouped by team in a brand-new tab. How It Works: Open your CBS Sports fantasy baseball league page. Click the Roster Checker icon. Set your desired thresholds and click Run Check. Review the violation report and notify your league-mates. Privacy & Security: We value your data. All processing happens locally in your browser. This extension does not collect, store, or share any of your league data.
