Sport Bowling Leagues

If you want to put your bowling skills to work on challenging lane conditions, the perhaps Sport Bowling Leagues are something you should consider! If your bowling center is registered for Sport Bowling Leagues and you who wish to have some fun and bowl with others also wishing to compete on the same relative, challenging lane conditions, then enter a Sport League this coming season. Find out how you will fare on USBC certified lane patterns dedicated to Sport League and Sport Tournaments.

USBC Sport Bowling is an optional membership level that presents the chance to experience a new challenge and satisfy a bowler’s competitive nature regardless of the bowler’s skill. Conducted on challenging lane conditions, Sport Bowling leagues and tournaments emphasize the bowler’s ability to deliver the bowling ball accurately and consistently, make necessary adjustments, read lanes, and convert spares — skills that will ultimately improve a bowler’s game.

The 2000 - 2001 bowling season saw the advent of Sport Bowling and became the PBA Experience Leagues where bowlers can complete with other peers on the same patterns the pro bowlers use on the National Tour. Although at the end of the 2010 - 2011 season, the contract is expiring between USBC and the PBA, Steve Wunderlich, Director of Membership Development and Sport Bowling at USBC Headquarters in Arlington, Texas, related to us during a recent conversation that he expects the contract to be renewed and extended very soon. If you enjoy bowling in the PBA Experience Leagues, very likely you will be able to continue into the next bowling season.

Today, Sport Bowling is recognized as the competitive standard in bowling. Almost every premier bowling tournament is rolled on Sport Bowling lane conditions — including USBC Championships and Lumber Liquidator Professional Bowlers Association Tour events. To maintain the integrity of Sport Bowling events, it is critical of the Sport Bowling program that the lane conditions present at the start of certified competition comply with Sport Bowling lane dressing specifications.

In addition, when using PBA Experience patterns, they should be representative of the specific PBA Experience pattern being used. Therefore, once lanes are conditioned for Sport Bowling leagues or tournaments, there shall be no bowling prior to the start of the competition, except for a reasonable amount of practice balls authorized by the competition, not to exceed thirty minutes.

Sport Bowling competition will guarantee that any honor score bowled qualifies for a Sport award. Of course, everyone has a great deal of interest in specifically what type of lane conditions does Sport Bowling competition require. The Sport Bowling Manual has all the information necessary to explain the lane patterns designated for use in these competitions and how the conditions must be monitored to ensure integrity and uniformity on all lane surfaces across the country.

To obtain and retain a Sport center certificate to host Sport Bowling competition, the bowling center must:
1. Be USBC certified.
2. Have access to a tape take-up device.
3. Have registered the center online on
4. Have an approved Sport Bowling lane dressing inspection on file with USBC Headquarters.
5. Submit graphs and/or tapes every week for every competition.
6. Be in compliance with all USBC certification requirements in addition to all Sport Bowling lane dressing requirements.

It is easy to understand how seriously the USBC takes Sport Bowling competitions. For bowlers, however, it is very enjoyable to see how well you might score on Sport lane patterns versus normal house lane conditions. In fact, the USBC provides an Average Adjustment scale to help convert the differences in average from the Sport conditions to house conditions.

Average Adjustment Chart

Sport Bowling conditions are more challenging than typical league conditions. Therefore, bowler averages under Sport Bowling conditions will typically be lower. We have confirmed this through the analysis of scores from Sport Bowling leagues and tournaments across North America. In an effort to equalize competition during standard tournaments, the following adjustment scale has been created for bowlers only having a Sport Bowling average. The adjustment scale is to be used under the following conditions:

*The scale applies to Sport Bowlers who ONLY have a Sport Bowling average.
*If a bowler has an established standard average, that average shall be used for standard tournaments.
*This adjustment scale is not considered a "re-rate" of the bowler. Its purpose is to allow for a fair adjustment to what would be expected of the bowler on a standard league condition.
*The adjustment scale does not supersede the ability of a tournament director to further adjust upward any bowler's entering average in a tournament.
*As additional data is obtained, slight changes to the scale may occur. If so, the updated scale will be published.
*The adjustment scale has been statistically designed to correct 95 percent of the Sport Bowling league averages to within 5 percent of a bowler's standard average.
