On November 12, 2019, Ken Rosenthal and Evan Drellich wrote an article in "The Athletic" detailing allegations that the Astros had used cameras to engage in potentially illicit sign stealing against opponents, relying on allegations from former Astros pitcher Mike Fiers as a public source and other allegations from unnamed sources. The Astros were alleged to have used scouts watching catchers' signs in real time behind the dugout at Minute Maid Park to crack the signs and banging a trash can loudly to indicate what kind of pitch was coming. The scandal rippled through the baseball world as internet sports personality Jomboy published videos that appeared to clearly show the scheme. Further allegations regarding other means of relaying signs, such as whistling, surfaced in subsequent weeks. MLB and Commissioner Rob Manfred announced a sweeping investigation into the allegations.
