The network confirmed Saturday that Lyons was dismissed after Friday's comments. He has been replaced for the remainder of the series by Los Angeles Angels announcer Jose Mota.
"Steve Lyons has been relieved of his FOX Sports duties for making comments on air that the company found inappropriate," network spokesman Dan Bell said.
Lyons had been working in the booth for the ALCS alongside Thom Brennaman and Piniella.
Piniella, approached before Saturday's Game 4, declined to comment on the situation except to say: "No, he's not here today."
