Toshiya Sugiuchi has been scratched from his start on Thursday against the Yakult Swallows because of discomfort in his left shoulder (he felt something during workouts today). While the injury does not appear to be serious, the Giants plan to play it safe and give Sugiuchi ten days of rest by taking him off the active roster on Thursday.
