Shinnosuke Abe (right shoulder) is slated to play in his first rehab game on May 25 against Yokohama as a designated hitter. The Yomiuri Giants were thinking about having him start at catcher, but decided it would be better to play it safe and take things slow. They have also decided to ease up on his return to the active roster — they were aiming for May 31, but will wait to set a date until they have a better idea of his condition.
For practices on May 21, Abe suited up and worked on his throws to each of the bases from home plate.
