The Yakult Swallows could add Yoshinori Sato (right shoulder) to their seventy-man roster during Inter-league play. He has pitched adequately (6 G, 1-1, 22.0 IP, 18 H, 12 BB, 18 SO, 9 R, 8 ERA, 3.27 ERA, 1.36 WHIP) and he has not had any problems with his shoulder. There are still things he is working on, like pitching on fewer days of rest and throwing more pitches per outing, but he could still give the team another option.

[UPDATE @ 10:06pm]
Yoshinori started a Ni-gun game against Lotte today and gave up four runs on seven hits over five plus innings of work. He faced twenty-six hitters, threw eighty-eight pitches, and topped out at 146km/h. He made the start on eight days of rest.
