DVS Analysis: 2015 Little League Baseball World Series

 
 

Japan won the 2015 Little League Baseball World Series by defeating Pennsylvania 18-11 in the championship game.  Japan has now won the 5 of the last 7 LLBWS championship games. 

HISTORY OF SUCCESS

Since 1967, two international regions, Asia-Pacific and Japan, have dominated the Little League Baseball World Series.  Over the last 48 years (1967-2015), teams from Japan, South-Korea, and Taiwan, have either won or been runner-up in 79% of all Little League Baseball World Series championship games. Each year, the United States sends 8 teams from 8 regions to the annual tournament, giving them a numerical advantage to win the overall tournament. However, in the last 47 years, teams from the United States have won only 30% of all championship games.

 As of 1/1/2016

2015 marks the second year we have performed an analysis of the Little League Baseball World Series.  In our 2014 analysis, we saw teams from both Japan and South Korea exhibit higher team DVS Scores but also rank consistently higher in performance variables. With another year of analysis and data, we wanted to see if the trend in pitching mechanics continued within the Japan and Asia-Pacific teams and monitor the fluctuations in DVS Scores among the regions of the United States. 

MEET THE TEAMS

The table below features the 16 teams who participated in the 2015 LLBWS. Teams sorted alphabetically.

2015 LLBWS ANALYSIS

The chart below depicts the average team DVS Score for all 16 teams in the 2015 Little League Baseball World Series.  Teams listed are ordered from lowest DVS Score to highest DVS Score.

For the second consecutive year, Japan had the highest DVS Score  with an average team DVS Score of 16. California finished a close second (15) to edge out Taiwan by .4 points. The worst team DVS Score belonged to the South Carolina.

2014 LLBWS vs. 2015 LLBWS

Comparing 2014 to 2015, the table below examines the fluctuation between the average team DVS Scores by region.  

Out of the 8 United States regions, 6 regions (Southeast, New England, Midwest, Great Lakes, Southwest, Mid-Atlantic) showed a decrease in team DVS Score's and continued to shower lower overall DVS Scores. The West region showed the largest increase of any team by moving from  11.43 to a 15.  

Out of the 8 International regions, 5 teams (Australia, Mexico, Europe-Africa, Latin America, Caribbean) improved their DVS Scores from 2015.  Asia-Pacific and Canada DVS Scores remained the same, and Japan's DVS Score dropped slightly from 16.6 to 16.

conclusion

The trends in DVS Scores remained consistent within the United States bracket with the exception of the West region. This years team out of Bonita, CA had an average team DVS Score of 15 compared to last year's West Region team DVS Score of 11.43.  All 7 other teams saw fluctuations within two DVS Score points but not significant enough to place the team into a different category of risk.

Internationally, we saw similar patterns surface from 2014 as well. Although the regions are widely dispersed the relative change in DVS Score was minimal.  However, we did see one large fluctuation ( 9.5 to 13.6) in the Caribbean Region;  This year the Caribbean Region was represented by a team from Dominican Republic whereas last year the Caribbean Region was represented by a team from Puerto Rico. Japan and Asia Pacific remained constant and continued to finish first and second respectively with highest average team DVS Score.

Two strong correlations have emerged from the analysis of two years worth of data. First, the overwhelming success of Japan and the Asia-Pacific and their respective DVS Scores.  Second,  The United States regions have consistently scored lower in comparison to Asia-Pacific and Japan.  On a youth level, the United States continues to be outperformed by Asia-Pacific and Japan dating back to 1967.  Now that we can quantify a pitcher's mechanics, we can document trends that lead to success at each level. 

We plan to study the LLBWS one more year to continue to document and analyze the mechanical trends at the youth level. At the conclusion of the 2016 LLBWS we will a formal analysis on three year's worth of data to see how relevant DVS Scores at a youth level are at predicting success in the tournament.
