Anyone up for a simple baseball trivia question?

[NewYorker]

In the history of Major League Baseball, there have only ever been three triple headers. Of those triple headers, from only one of them both teams involved still exist with the same names today as they did then. Three simple trivia questions from this.
-What were the two teams?
-What was the date of the triple header (giving the year alone is fine)?

-Which team won the triple header and how many games of the three that particular day did that team win?

That would be interesting, I would like to go to one of those today.

The Cincinnati Reds and Pittsburgh Pirates played three games on October 2, 1920. The Reds won the triple header, winning the first two games by scores of 13-4 and 7-3 and losing the third game 6-0.
