What ballpark was Pete Rose playing in when he broke Ty Cobb's career hit record?

Answer 1

Riverfront Stadium, in Cincinnati, Ohio.
According to MLB, Ty Cobb had 4,191 career base hits. Rose got his 4,192 base hit at Riverfront Stadium in Cincinnati on September 11, 1985 off of Eric Show of the San Diego Padres.

However, in 1981, independent research found a game Cobb played in 1910 where he got 2 base hits but was credited with 4. MLB has refused to address the discrepancy, with then Commissioner Bowie Kuhn stating that "The passage of 70 years, in our judgment, constitutes a certain statute of limitation as to recognizing any changes.". While MLB continues to state that Cobb had 4,191 career base hits, most reference books and encyclopedias put Cobb at 4,189. Two of the largest and most popular Baseball references, Baseball Almanac and Baseball Reference, each list Cobb with 4,189 career hits.

If Cobb had 4,189, Rose's 4,190th came on September 8, 1985 at Wrigley Field in Chicago off of Reggie Patterson of the Cubs.
