According to Nikkan Sports, the Softbank Hawks will apparently be using the following rotation for the Final Stage of the Climax Series:
Toshiya Suiguchi, Tsuyoshi Wada, Dennis Houlton, Kenji Otonari, Yao-Hsun Yang, and then back to Sugiuchi.
Shinsuke Ogura and Hiroki Yamada will be used out of the bullpen.
Yamada will get some "practice" out of the pen at the Phoenix League; Houlton and Otonari are also scheduled for Phoenix League appearances: Houlton will get a start on the 9th against Seibu and Otonari a start against Yomiuri on the 10th.
Other than Ogura and Yamada, it seems the rest of the bullpen will consist of Keisuke Katto, Masahiko Morifuku, Takehito Kanazawa, Tadashi Settsu, Brian Falkenborg, and Takahiro Mahara.
The Hawks will probably go with 12 pitchers and add / remove Yang and Houlton as needed.
