International Sports Management

San Diego Sports Authority (SDSA)

Japanese Industrial League

 The Japanese Industrial League, established in 1920, is operated by the Japanese Amateur Baseball Association throughout Japan. Although it is unaffiliated with the Nippon Professional Baseball league, it still manages to fund a full season of about 70-80 games including 2 big tournaments and about 10 smaller ones throughout the season, all made possible by the big Japanese companies who own the teams like Toyota, Honda, Toshiba, and many others. This leagues skill level is just as good if not better than the minor league system in NPB. To play in this league you must also work for the company of the team you play for. Which is quite the step up from the company softball leagues we often hear about, and is a little harder for foreigners to join, but not impossible. In fact, 5 players from the SDSA tryout in San Diego received an invite to test their luck in the Industrial Leagues preseason workout, where they will try to earn a roster spot on one of the teams for the 2015 season. If they're picked up, they will be signed to a contract for the next 10 months, and have a shot of making it to the Japanese Big Leagues if they do well this season. If signed, they will also be working for the company as well, and their schedules will include a balance of work and training at the business and on the field in their day to day activities. 


SAMURAI 2015 Reform

SAMURAI San Diego now divided into two teams

2015 is going to bring some big changes to the SAMURAI organization. We are splitting the program up into two teams so we can focus on the players needs, and help develop more ball players depending on their individual level/goals. Team one will be the SAMURAI "future", which focuses on players who are fresh out of high school and want to play for a Jr. College in the Spring of 2016. Team two will be the SAMURAI "elite", which will focus on players who are looking to play at a 4-year college program, or pursue their dream of playing Pro-ball internationally. The seasons are both the same length: 6/20-7/19. So far, the SAMURAI program has sent 5 players from the 2014 roster to Japan to play Pro-ball, and has given many others the opportunity and exposure to play college ball.

After a successful season with the SAMURAI, Yoshihiro Doi has returned to Japan to continue working as a TV Analyst specializing in baseball. He will also make a guest appearance for the Kasukabe Kyoei High School baseball team (the High School Yoshihiro attended and played for back in the day and was runner-up in the National Championship for all of Japan) as they fight to win the top level High school tournament to become Japan's number one High School baseball team. So far, they won a regional tournament where 162 teams competed to make it to the National Tournament. The Kasukabe Kyoei team will make their first appearance in the National tournament starting August 9th, 2014. The SAMURAI are thankful for the help that Coach Yoshihiro offered them this season, and wish the Kasukabe Kyoei High School team the best of luck in their endeavors. The SAMURAI appreciate the help of SDSA and its management for organizing the season and providing an effective coaching staff for this season.

SAMURAI San Diego Update...

SAMURAI post game
SAMURAI post game

With only 3 games left in the season, the SAMURAI San Diego are looking to finish strong. So far this season, the SAMURAI San Diego's record is 12-4-1, the tie being the result of an extra innings game that ran out of light. In the last eight games the SAMURAI San Diego have won six and lost two, in this span they've scored 72 runs, and given up 30. This is the result of good defense, strong/clutch offense (most runs being scored with two outs), and a solid pitching staff. As the season goes on, the team continues to build strength and momentum offensively, and the pitching is giving up fewer extra base hits and walks, which ultimately means lower runs scored against. A lot of the pitchers success is due to the return of pitching coach and former Japanese Big League pitcher, Yoshihiro Doi. Who's been working with the staff on any mechanical, and mental questions they have when taking the mound. Since Coach Yoshihiro has taken over the pitching rotation, the SAMURAI San Diego have continued to improve in all aspects of the game.
