I was the one, or one of the people, who said Jacobs field is a pitchers park, and it is. I looked up espn's park factor stat and you're right, it lists Jacobs field as one of the most hitter friendly parks in baseball. Either that stat is completely useless or there was an error in calcing Jacob field.
In the last 3 years the Guardians have scored 129 more runs on the road than at home. They allowed 108 more runs on the road. Every single year for the last 3 years(and probably more than that. I didn't research it further," they have both scored more runs on the road, and allowed more. Yet, park factor lists it as the most hitter friendly park in the majors. Not possible.
