A third Major League team may soon be dealing with ballpark issues.

Rob Manfred is in Milwaukee and will hold a press conference in which he urges major, long-term renovations to American Family Field, the home of the Brewers, according to a report.

The report indicates that the renovations -- upgrades to seating areas, concourses and gathering spaces -- would cost an estimated $428 million over the course of the next 20 years.
