Here are some aggregate break statistics from the 33 9-Ball matches streamed by Accu-Stats from the 2014 U.S. Open 9-Ball Championship in Chesapeake, VA.

The conditions for this event included: Diamond 9-foot table with pro-cut pockets, blue Simonis 860 cloth, Diamond wooden rack, Aramith Tournament balls, measles cue ball, winner breaks, breaker racks for himself with the 9-ball on the foot string (spot moved up approx. 4") and the 2-ball at the back of the rack, break from the box (approx. 9" to each side of the long string), a 9-ball made on the break spots up if it went in either of the two foot-rail pockets, the break is illegal unless at least 3 balls pass the side pockets or are pocketed, foul on all balls, jump cues are allowed, and all slop counts (except as stated for 9-balls on the break). A 40-sec. shot clock (with one extension per rack) was used on the full-production matches.

The 33 matches (592 games tracked) were as follows. 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.

Overall results -- The breaker made at least one ball (and did not foul) 53% of the time (315 of 592), won 50% of the games (298 of 592), and broke and ran 20% of the games (119 of 592).

Here's a little more detailed breakdown of the 592 games.

Breaker made at least one ball and did not foul:
  • Breaker won the game: 204 (34% of the 592 games)
  • Breaker lost the game: 111 (19%)

Breaker fouled on the break:
  • Breaker won the game: 12 (2%)
  • Breaker lost the game: 41 (7%)

Breaker broke dry (without fouling):
  • Breaker won the game: 82 (14%)
  • Breaker lost the game: 142 (24%)

Therefore, whereas the breaker won 50% (298) of all 592 games,
  • He won 65% (204 of 315) of the games in which he made at least one ball on the break and did not foul.
  • He won 23% (12 of 53) of the games in which he fouled on the break.
  • He won 37% (82 of 224) of the games in which he broke dry but did not foul.
  • He won 34% (94 of 277) of the games in which he either fouled on the break or broke dry without fouling.

9-balls on the break:
The 119 break-and-run games included just 6 9-balls on the break (1.0% of the 592 breaks). In addition, 3 9-balls (0.5% of the breaks) were made that went in one of the two bottom pockets and had to be spotted rather than counting as wins.

Illegal breaks:
An illegal break (failure to have at least 3 balls pass the side pockets or be pocketed) was called on only 4 of the 592 breaks. Strangely enough, 2 of those 4 were in the final match. One of the 2 in the final match was in the final game; Orcollo surrendered the table on a wet break and Van Boening ran out for the match win. But the total number of illegal breaks was so small that I just ignored those violations for purposes of these stats rather than create any additional categories.
