The Hanshin Tigers have been hit by a string of injuries that has depleted their middle infield. Takashi Toritani suffered a laceration on his right index finger nail bed on the 15th; Keiichi Hirano a contusion on his left thigh on the 18th; and Yamato (dislocated shoulder) and Katsuhiko Saka (right index finger) are also out as well.
The Tigers do have other infielders they can turn to, like Hiroki Uemoto and Kentaro Sekimoto. They also have Kosei Fujii (Ikusei; 21 years old; 75 PA, .294 / .333 / .397 Ni-gun 2011), Fumiya Araki (23 years old; 85 PA, .200 / .238 / .200 Ni-gun 2011), and Masashi Nohara (23 years old; 111 PA, .183 / .300 / .269 Ni-gun 2011), but the team doesn't appear to think any are ready to step in full-time (if that should become necessary). Still, if Hirano needs time off, the Tigers may call up Nohara and / or Araki to help fill some of the void.
Past that, it appears the Tigers may be open to making a move.
According to Sanspo, the people at the top have given members of the front office the green light to make a move for an infielder that can play short, provided the move makes sense for the team. Some names the Sanspo article mentions: Keisuke Kaneko (ORI), Haruki Kurose (SEI), Wataru Nishimura (RAK), and Keisuke Mizuta (CHU).
