Here are some aggregate break statistics from the 38 9-Ball matches streamed this past week from the 2019 U.S. Open 9-Ball Championship at the Mandalay Bay Resort and Casino in Las Vegas, NV. This was a 252-player event produced by Matchroom Sport. Streaming was on Facebook (free) for the first 3 days and on DAZN (ppv) for the last 3 days. The format was double-elimination down to 16 players and then single-elimination to the end. Joshua Filler won the tournament, defeating Wu Jiaqing in the final match.

Conditions -- The conditions for these streamed matches included:
- Diamond 9-foot table with pro-cut pockets;
- blue Simonis cloth;
- Accu-Rack racking template in double-elim. stage, triangle rack in single-elim. stage;
- Aramith TV Tournament balls with the measles cue ball (except different balls were used in the first 10 streamed matches);
- referee racks with the 9-ball on the foot spot (2-ball need not be at the back of the rack);
- winner breaks from anywhere behind the head string, with no up-close inspection of the rack;
- no 3-point (illegal-break) rule;
- foul on all balls;
- jump cues allowed;
- 40-sec. shot clock (80 sec. after the break) with one extension per player per rack; and
- all slop counts.​

The 38 matches (619 games) on the main streaming table were as follows, shown in the order in which they were played. These 38 matches represented 7.7% of the event's total of 495 matches played (excludes the 8 forfeited matches).

Overall results
Successful breaks (made at least one ball and did not foul) -- 81% (324 of 400) for match winners, 73% (160 of 219) for match losers, and 78% (484 of 619) in total​
Breaker won the game -- 76% (302 of 400) for match winners, 46% (101 of 219) for match losers, and 65% (403 of 619) in total​
Break-and-run games -- 39% (157 of 400) for match winners, 24% (53 of 219) for match losers, and 34% (210 of 619) in total​

Here's a breakdown of the 619 games (for match winners and losers combined).

Breaker made at least one ball and did not foul:
Breaker won the game: 344 (56% of the 619 games)
Breaker lost the game: 140 (23%)​

Breaker fouled on the break:
Breaker won the game: 3 (0%)
Breaker lost the game: 18 (3%)​

Breaker broke dry (without fouling):
Breaker won the game: 56 (9%)
Breaker lost the game: 58 (9%)​

Therefore, whereas the breaker won 65% (403 of 619) of all games,
He/she won 71% (344 of 484) of the games in which he/she made at least one ball on the break and did not foul.
He/she won 14% (3 of 21) of the games in which he/she fouled on the break.
He/she won 49% (56 of 114) of the games in which he/she broke dry but did not foul.
He/she won 44% (59 of 135) of the games in which he/she either fouled on the break or broke dry without fouling.​

Break-and-run games -- The 210 break-and-run games represented 34% of all 619 games, 52% of the 403 games won by the breaker, and 43% of the 484 games in which the break was successful (made a ball and didn't foul).

The 210 break-and-run games consisted of 3 four-packs (2 by Van Boening and 1 by Shaw), 11 three-packs, 35 two-packs, and 95 singles. No one broke and ran more than 4 games in a row in these streamed matches.

9-Balls on the break -- The 210 break-and-run games included 4 9-balls on the break (0.6% of all breaks).

Miscellany from the data for the 2019 U.S. Open 9-Ball Championship:
[This relates only to the 38 streamed matches, not to all matches in the event.]

• The most balls made on a single break was 4, done just twice -- once by Dennis Hatch (including a 9-ball) and once by Filler (he won the game after pushing out).

• The average number of balls made on the break was 1.3 (this includes dry and fouled breaks). On successful breaks (made at least one ball and did not foul), the average was 1.6.

• 52% (322 of 618) of the games ended in one inning – 34% (210) won by the breaker (B&R) and 18% (112) won by the non-breaker. Eight percent (52 of 618) of the games lasted more than 3 innings. [Note: Most of 1 game was not shown on the stream, hence the use of 618 games in total here rather than 619.]

• 40% (248 of 619) of the games were run out by the player who was at the table following the break. These run-outs were:
- By the breaker after successful breaks (B&R games) – 43% (210 of 484)
- By the non-breaker after fouls on the break – 76% (16 of 21)
- By the non-breaker after dry breaks – 19% (22 of 114)

• The player who made the first ball after the break:
- Won the game in that same inning 62% of the time (382 of 614)
- Won the game in a later inning 13% of the time (77 of 614)
- Lost the game 25% of the time (155 of 614)
[Note -- total games used here are 614 rather than 618 to eliminate the 4 games in which no ball was made after the break.]

• The loser won an average of 5.1 games in the 37 races to 11 (excludes the final match). Four matches went to hill/hill; two matches finished with no games won by the loser.

• The average elapsed time for the 37 races to 11 was 97 minutes, averaging 6.0 minutes per game. The elapsed time was measured from the lag until the winning ball was made (or conceded), so it includes time for racking and commercial breaks. Commercial breaks were significant in the final 15 matches, generally occurring after every 3 games in a match, and lasting about 3 minutes each.

• The match that was longest in elapsed time, at 156 minutes, was Chang d. Liu 11-10. The match that was highest in average minutes per game, at 7.6, was Teutscher d. Woodward 11-5.

• The match that was shortest in elapsed time, at 50 minutes, was Shaw d. Deuel 11-1. Two matches tied for lowest in average minutes per game, at 4.2 -- the Shaw/Deuel match and Van Boening d. Hatch 11-3.

• Breaking fouls averaged 1 for every 29.5 games, other fouls 1 for every 4.7 games, and missed shots about 1 for every 2.4 games.

• About 36% of the games involved one or more safeties.

78% break success for the field seems terrific.

I'm interested in the difference between the hand-racked results vs the templates.

thanx, AtLarge

At least on the following measures, and perhaps unexpectedly -- essentially no difference:

Successful breaks (made at least one ball and did not foul):
Template -- 78% (279 of 358)
Triangle -- 79% (205 of 261)​

Breaker won the game:
Template -- 65% (234 of 358)
Triangle -- 65% (169 of 261)​

Break-and-run games, on all breaks:
Template -- 34% (121 of 358)
Triangle -- 34% (89 of 261)​

Break-and-run games, on successful breaks:
Template -- 43% (121 of 279)
Triangle -- 43% (89 of 205)​

Many thanks for doing and posting all this work. I did find the results between template & triangle racks very interesting.

Me, too. I expected the template to produce higher success rates than the triangle. But maybe the reason is that the triangle was used on just the last 15 matches, which probably involved many of the better breakers. So their better breaking skills made up for the inherent difference between template and triangle.

The 38 streamed matches involved 47 different players. 30 of them appeared in streamed matches just once, 10 appeared twice, 3 appeared three times, 3 four times (Filler, Wu, and Shaw), and 1 five times (Van Boening). Here are some stats for each of the 4 players who appeared at least four times (they finished 1st, 2nd, 9th/16th, and 9th/16th in the event).

4-player total -- 86% (150 of 174)
Other 43 players -- 75% (334 of 445)
All 47 players -- 78% (484 of 619)​

4-player total -- 79% (138 of 174)
Other 43 players -- 60% (265 of 445)

At Large, would you have Shaw's BNR %(of all breaks).

I think I saw him on the TV table 4 matches

Thank you for spotting that; you are correct that he appeared on stream 4 times. So I have edited post #11 to include his stats.

Regarding pushes:

Conventional wisdom is that the player who pushes out is at a disadvantage, because it is the other player who then has the choice on whether to shoot.

Out of 618 games in the 38 streamed matches I watched for the 2019 U.S. Open Championship, 73 games (12%) involved a push out, and the results were as follows:
  • Breaker pushed and won the game -- 34
  • Breaker pushed and lost the game -- 23
  • Non-breaker pushed and won the game -- 7
  • Non-breaker pushed and lost the game -- 9
78% (57 of 73) of the pushes were by the breaker and 22% by the non-breaker, the same split as for successful vs. unsuccessful breaks.

Overall, the person who pushed won 41 of the 73 games (56%) and lost 32 (44%). Breakers who pushed won nearly 50% more games than they lost, while non-breakers lost a couple more games than they won.

Of the 73 pushes, 36 were returned (passed back to the pusher to shoot), and the pusher won 19 of those 36 games (53%). The pusher won 59% (22 of 37) of the games that were not passed back to him.

As usual for stats on pushes, the numbers are small, so generalizations should not be made from them.
