Ozzie Guillen absolutely loathes the idea of an automated strike zone in the MLB ... telling TMZ Sports he thinks robot umps are "the worst thing I've ever heard in my life."
The former Chicago White Sox manager went in on the idea when we asked him this week about the potential rule change -- saying he has no clue how it'd make the game better.
"I hope [the rule change] happens after I die," Guillen said, "because I'll be very, very vocal about it."
The MLB is considering the move down the road -- after it implemented automated strike zones for the 2022 Triple-A season.
