Kodai Senga was taken off the active roster today because of lingering tightness in his back.
Senga left a start on May 16 after throwing just nine pitches. He made his next start on twelve days of rest on May 28 and pitched eight strong innings. He gave up five runs over 7.2 innings during his next start on June 4.
Senga sat down with Kimiyasu Kudo to discuss his condition yesterday. Their talks continued to today and the two agreed the twenty-four-year-old should focus on his recovery, since pitching through the tightness might lead to a more serious condition.
[UPDATE 6/15 @ 10:36pm]
The Softbank Hawks are not planning to rush Senga back to the active roster just so that he can get one more start during Inter-league play. They will most likely wait until after Inter-league play to activate him.

Senga’s return to the active roster will be pushed back to the Rakuten series that begins on June 30 because he needs the extra time.
