SEATTLE — Daisuke Matsuzaka was to return to Boston for more tests on his fatigued pitching shoulder, leaving at least his next start in jeopardy.
The right-hander left his start in Seattle on Tuesday after four innings. He threw two seemingly routine warm-up pitches before the bottom of the fifth, then departed with what the Red Sox continued to vaguely term Wednesday as “shoulder fatigue.”
