Press conferences are a great way to hear directly from the players. Unfortunately, TV channels don’t show many press conferences. As a fan, you have to rely on tournament websites, YouTube videos, etc to catch what the players have to say.
ASAP Sports Transcripts is a repository that includes transcripts from most tennis tournaments. The transcript archive goes back to 1992. In addition to tennis transcripts, you can find transcripts for a number of other sports including basketball, baseball, and soccer there.
There is usually a slight delay of 1 to 2 days before the interview gets posted. But it’s a goldmine. I had a lot of fun reading interview transcripts after iconic matches in the past. Hope you find something interesting there!
