The Red Sox did it in the 7th inning at Fenway versus the Tigers in a 23-3 win on June 18, 1953. The all-time record is 18 by the Cubs (then called the White Stockings) against the Detroit Wolverines in a 26-6 win on September 6, 1883.

In other words, most of us never had seen this in our lifetimes.
