Break Stats -- 2019 International 9-Ball Open, Oct./Nov. 2019

AtLarge · Nov 3, 2019

Here are some aggregate break statistics from 33 of the 34 matches streamed this past week by Accu-Stats from the 2019 International 9-Ball Open at the Sheraton Norfolk Waterside Hotel in Norfolk, VA. These matches were streamed by Accu-Stats on a pay-per-view basis. Jayson Shaw defeated Maximillian Lechner in the Finals to win the event.

Conditions -- The conditions for these streamed matches included:

- Diamond 9-foot table with pro-cut pockets;

- blue Simonis cloth;

- Accu-Rack racking template;

- Aramith TV Tournament balls with the measles cue ball;

- winner breaks from the box -- 9" to each side of the long string;

- referee racks with the 9-ball on the foot spot and the 2-ball at the back of the rack;

- the break is illegal (and non-breaker has an option to shoot) unless at least 3 object balls touch the plane of the head string or are pocketed, but this requirement is waived if 2 object balls are pocketed;

- foul on all balls;

- jump cues allowed;

- for "full production" matches, a 40-sec. shot clock with one automatic extension per player per rack (no violation if the player is down on the shot before the clock expires and shoots before getting up); and

- all slop counts.

The 33 matches (595 games) tracked were as follows, shown in the order in which they were played. These 33 matches represented 17.4% of the event's total of 190 matches played. The figures in parentheses for some of the matches are the Accu-Stats Total Performance Averages (TPA), as calculated by Accu-Stats and shown on the stream.

[Note: These stats exclude the first 16 games from the first streamed match (when I was not watching) and 3 games from the Finals match (when the stream was down). So the total number of games tracked was 576.]

Overall results

■ Successful breaks (broke legally, made at least one ball, and did not foul) -- 72% (247 of 344) for match winners, 56% (129 of 232) for match losers, and 65% (376 of 576) in total

■ Breaker won the game -- 63% (215 of 344) for match winners, 40% (92 of 232) for match losers, and 53% (307 of 576) in total

■ Break-and-run games on all breaks -- 31% (108 of 344) for match winners, 17% (40 of 232) for match losers, and 26% (148 of 576) in total

■ Break-and-run games on successful breaks -- 44% (108 of 247) for match winners, 31% (40 of 129) for match losers, and 39% (148 of 376) in total

■ Illegal breaks -- 12% (42 of 344) for match winners, 20% (46 of 232) for match losers, and 15% (88 of 576) in total

Here's a breakdown of the 576 breaks (for match winners and losers combined).

Legal, made at least one ball, and no foul:

Breaker won the game: 240 (42% of the 576 games)

Breaker lost the game: 136 (24%)

Illegal, made at least one ball, and no foul:

Breaker won the game: 12 (2%)

Breaker lost the game: 25 (4%)

Fouled (includes 3 breaks that were both fouled and illegal):

Breaker won the game: 2 (0%)

Breaker lost the game: 38 (7%)

Legal, dry, and no foul:

Breaker won the game: 32 (6%)

Breaker lost the game: 43 (7%)

Illegal, dry, and no foul:

Breaker won the game: 21 (4%)

Breaker lost the game: 27 (5%)

Therefore, whereas the breaker won 53% of all games (307 of 576),

He won 64% (240 of 376) of the games in which he broke legally, made at least one ball, and did not foul (successful breaks).

He won 32% (12 of 37) of the games in which he broke illegally, made at least one ball, and did not foul.

He won 5% (2 of 40) of the games in which he fouled on the break (whether wet, dry, legal, or illegal).

He won 43% (32 of 75) of the games in which he broke legally, dry, and did not foul.

He won 44% (21 of 48) of the games in which he broke illegally, dry, and did not foul.

He won 34% (67 of 200) of the games in which the break was illegal, fouled, or dry (all unsuccessful breaks).

Break-and-run games -- The 148 break-and-run games represented 26% of all 576 games, 48% of the 307 games won by the breaker, and 39% of the 376 games in which the break was successful (made a ball, legal, no foul).

The 148 break-and-run games consisted of 1 4-pack (Filler), 5 3-packs (Gomez, Filler, Alcaide, Pagulayan, and Lechner), 25 2-packs, and 79 singles.

9-balls on the break -- The 148 break-and-run games included 4 9-balls on the break (0.7% of the 576 breaks). With the Accu-Rack, the 9-ball tends to remain close to its original position.

Miscellany from the data for the 2019 International 9-Ball Open
[This relates only to the 33 streamed matches I tracked, not to all matches in the event.]

• No one made more than 3 balls on a single break.

• The average number of balls made on all breaks was 1.1. On successful breaks (legal, made at least one ball, and did not foul), the average was 1.5, and the distribution was 56% 1 ball, 37% 2 balls, and 7% 3 balls.

• 52% (298 of 576) of the games ended in one inning – 26% (148) won by the breaker (B&R) and 26% (150) won by the non-breaker. 9% (54 of 576) of the games lasted more than 3 innings.

• 40% (230 of 576) 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) – 39% (148 of 376)
- By the non-breaker after wet but illegal breaks -- 49% (18 of 37 )
- By the non-breaker after fouls on the break – 85% (34 of 40)
- By the non-breaker after dry breaks – 24% (30 of 123)

• The player who made the first ball after the break:
- Won the game in that same inning 67% of the time (383 of 572)
- Won the game in a later inning 13% of the time (74 of 572)
- Lost the game 20% of the time (115 of 572)
[Note -- total games used here are 572 rather than 576 to eliminate the 4 games in which no ball was made after the break.]

• For the 32 races to 11 (i.e., excluding the Finals race to 13), the loser won an average of 6.8 games. Four matches went to hill/hill; the most lopsided match was one at 11-1.

• The longest race to 11 in elapsed time, at 160 minutes, was Ouschan d. Ekonomopoulow 11-9. The shortest matches in elapsed time, at 64 minutes, were Filler d. Dudanets 11-4 and Aranas d. Orcollo 11-1 . The elapsed time was measured from the lag until the winning ball was made, so it includes time for racking and timeouts.

• The average elapsed time for the races to 11 was 107 minutes.

• The average minutes per game for all 33 matches was 6.0.

• The match highest in average minutes per game, at 8.0 min./game, was Ouschan d. Ekonomopoulos 11-9. The matches lowest in average minutes per game, at 4.3 min./game, were Filler d. Dudanets 11-4 and Filler d. Appleton 11-10.

• Breaking fouls averaged 1 for every 14.4 games, other fouls 1 for every 6.0 games, and missed shots about 1 for every 2.1 games.

• About 37% of the games involved one or more safeties.

Curious, how do you compile all of this? Looks tedious as all get out.

Thanks again AtLarge, for your work in this area. The beginning of any endeavor always needs to be a great Start & the Break Shot in Pool is one of them. Maintaining control of the game, after the Break Shot, is omnipotent. Your posted info gives us all an insight into the way tournaments are won & who wins them...

How? Pay close attention and take notes. Tedious? In some matches, sure; in others, just fun.

Here's a comparison of some results for this year's event vs. last year's. The only significant difference I know about in the conditions (equipment and rules) is that the "3-point" rule for determining a legal break was waived this year (i.e., did not apply) if 2 balls were pocketed.

Breaks on which at least one ball was pocketed (includes all wet breaks even if illegal or fouled)

2019 -- 78% (449 of 576)
2018 -- 77% (537 of 699)

Illegal breaks (whether wet, dry, or fouled)

2019 -- 15% (88 of 576)
2018 -- 14% (99 of 699)

Successful breaks (broke legally, made at least one ball, and did not foul):

2019 -- 65% (376 of 576)
2018 -- 62% (435 of 699)

Breaker won game -- on all breaks:

2019 -- 53% (307 of 576)
2018 -- 52% (363 of 699)

Breaker won game -- on legal breaks:

2019 -- 56% (274 of 488)
2018 -- 54% (326 of 600)

Breaker won game -- on illegal breaks:

2019 -- 38% (33 of 88)
2018 -- 37% (37 of 99)

Break-and-run games -- on all breaks:

2019 -- 26% (148 of 576)
2018 -- 22% (154 of 699)

Break-and-run games -- on successful breaks:

2019 -- 39% (148 of 376)
2018 -- 35% (154 of 435)

Average number of balls made on the break:

2019 -- 1.13 on all breaks, 1.51 on successful breaks
2018 -- 1.15 on all breaks, 1.56 on successful breaks

Games ending in one inning:

2019 -- 52% (298 of 576)
2018 -- 48% (337 of 699)

Run-outs from first shot after break:

2019 -- 40% (230 of 576)
2018 -- 37% (257 of 699)

Games won by player who made the first ball after the break:

2019 -- 80% (457 of 572)

Total Performance Averages

Accu-Stats calculated and posted final TPAs for 23 of the 33 streamed matches I watched (see post #1 above). Some tidbits:

• The distribution of TPAs was

950+ -- 3 in total (3 for match winners, 0 for match losers)

900-949 -- 15 (13, 2)

850-899 -- 17 (5, 12)

800-849 -- 8 (1, 7)

750-799 -- 3 (1, 2)

< 750 -- 0

• So "900's" were posted in 18 of the 46 player appearances (39%). Sixteen of the 23 match winners posted 900 scores (70%), whereas only 2 of the match losers did so.

• Tournament winner Shaw appeared on stream 5 times. No TPAs were given for one of those appearances, For the other 4, all of his TPAs were in the 900's, with a high of .955 and a mean of .923.

• Arithmetic means for the 23 matches -- .906 for match winners, .852 for match losers, .879 combined.

• Medians for the 23 matches -- .910 for match winners, .859 for match losers, and .881 combined.

[Note: The highest posted score was Filler's .960 in defeating Kazakis on Friday. But I believe Aranas would have had a higher score in his 11-1 win over Orcollo on Friday.]

Only 26% Brk N Run??
Hope all the "template haters" take note.
I love the Accu-rack. I think it's the best of them.
