To provide a specific number of hard court singles victories, we would need more detailed data from tennis matches in 2023. However, I can provide some insights from various sources that highlight key players' achievements and statistics related to hard court wins:

1. Top Players' Hard Court Wins:

   • Roger Federer has won 71 out of his 103 ATP singles titles on hard courts.
