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.
