US Open, Qualification ATP: Luca Nardi vs Federico Cina

Platform comparison

Market context

The match has already produced the key change in the last 24 hours: Federico Cinà advanced after Luca Nardi retired trailing 6-4, 3-0, so the market should now be read as a completed on-court outcome rather than an open qualifier. That makes the crowd-implied 0% YES look stale against the live tournament record.

For context, this was a first-round men’s qualifying match at the US Open, with both Italians listed in the main qualifying draw and the fixture scheduled for Court 13. Pre-match listings had Nardi slightly ahead in rankings, but the in-play and results pages now show Cinà as the winner and Nardi marked retired, which is the decisive signal for settlement direction if the market is still open.

The main catalysts to watch are official draw updates, the published qualifying order of play, and any correction from the event site or data feed if there is a timing discrepancy between scheduled start and recorded result. The settlement window runs to 1 September, but the match result itself appears to be settled by retirement rather than cancellation, so any residual uncertainty would centre on whether the market’s data source recognises the completed result cleanly.
