Here are some aggregate break statistics from the last two days of the 2021 US Open Pool Championship played September 13-18, 2021 at Harrah's Resort Atlantic City, in New Jersey, with pay-per-view streaming in the USA on DAZN. This was a 243-player 9-Ball event produced by Matchroom Sport. Carlo Biado won the tournament, defeating Aloysius Yapp in the final match.
First-round matchups included the seeding of 92 players based on their world ranking and performance in prior major events. The event was double elimination down to the final 16 players (8 on the winners' side and 8 on the one-loss side). It was then single-elimination play from that point to the conclusion. Races were to 9 during the first two days of play and then 11 for the last 4 days except for the Finals (race to 13). The main commentators in these streamed matches were Phil Yates, Jeremy Jones, Nick Schulman, and Karl Boyes. The referees were John Leyman, Marcel Eckardt, and Brendan Moore. The MC/announcer/interviewer was Michael Bridge.
Conditions -- The conditions for the streamed matches I tracked included:
These stats are for all 7 matches (132 games) streamed on the final two days on the feature table (Table 1) in the main arena. These matches constituted just 1.5% of the total of 482 matches played in the tournament (21 scheduled matches did not occur because of withdrawals and forfeits), but 47% of the matches in the single-elimination portion of the event (final 16 players). These 7 matches are listed here in the order in which they were played.
