Tsuyoshi Wada started tonight’s game against the Seibu Lions and gave up two runs (both earned) on five hits over five innings of work. His night ended after five innings and sixty-seven pitches because he started to develop tightness in his left elbow during the fourth inning.
[UPDATE 4/12 @ 10:48pm]
Wada was taken off the active roster on April 11 as a precaution. Kimiyasu Kudo told reporters Wada’s condition was not serious and that he was only going to skip one start.
[UPDATE 4/18 @ 11:06pm]
Wada ended pitching practices early during workouts at the Chikugo facilities earlier today. Kudo told reporters they did not want to rush the veteran. He may not be able to return to the active roster for the Rakuten three-game series that begins on April 21.
[UPDATE 4/19 @ 4:17pm]
Wada ended his bullpen session on April 18 after throwing just fifteen pitches. He visited a hospital in Kanto today for tests.

[UPDATE 4/19 @ 9:06pm]
Wada was diagnosed with inflammation in his left elbow today. He will not do any throwing for least a week (or until the inflammation goes away). It will most likely take over a month for a full recovery. He will join the rehab group on April 20.
[UDPATE 4/27 @ 4:03pm]
Wada played catch on April 27, for the first time in nine days. He lightly threw the ball for about ten minutes at a distance between twenty and thirty meters.
[UPDATE 5/11 @ 6:08pm]
Wada threw forty-five pitches in the bullpen and mixed in some off-speed pitches. He threw only fastballs during his last session on May 5.
