Associated Evidence Record
Evidence for
The Camera Feed and Trash-Can Signals MLB Found in the Astros’ Sign-Stealing Operation
Investigative question
What did MLB establish about the Astros’ electronic sign-stealing operation, and what is the evidence-based connection—if any—to the 2018 ALCS?
Event boundary
The reported conduct began during the 2017 season, continued through the 2017 postseason and part of the 2018 season, and was addressed by MLB’s January 2020 investigation and disciplinary ruling. The captured evidence does not establish that the scheme was used specifically during the 2018 ALCS.

| Claim 6 | MLB suspended Astros general manager Jeff Luhnow and manager A.J.

Evidence assessment
The captured sources support a strong, institutionally documented finding that the Astros used electronic equipment to steal signs during the 2017 season and postseason and during part of the 2018 season. They also support major MLB sanctions against the organization and its senior baseball executives. The evidence does not establish that the scheme was used specifically during the 2018 ALCS, so the original title should be reframed rather than preserved.
