[12/15/2016] Hideki Kuriyama still mulling over opening day starter

If Shohei Otani makes the World Baseball Classic roster, Hideki Kuriyama might not give him the opening day start. There is enough time in the schedule for Otani to prepare (he would get at least seven days of rest if Samurai Japan makes it to the finals), but there are other factors to consider on top of possible fatigue, like having to readjust to the NPB baseball after working with the WBC baseball.

Extra rest might be beneficial for Otani. Masahiro Tanaka followed a similar path in 2013 (the opening day start went to Takahiro Norimoto) and went on to go 24-0 before heading off to the Majors.

Kohei Arihara and Hirotoshi Takanashi are possible alternate opening day starters, if Kuriyama decides not to go with Otani.

He set a new NPB record by recorded three consecutive games with two home runs.

Pacific League


Kohei Arihara, Nippon Ham (First Time)
4 G, 3-1, 30.2 IP, 1.47 ERA, 0 CG, 21 SO, 5 ER

He pitched eight shutout innings against Softbank on July 2 and Lotte on July 9 and seven shutout innings against Orix on July 22. He lost his start on July 29 against Softbank, but still played a big part in helping his team finished 17-4 in July.


Ryoichi Adachi, Orix (First Time)
22 G, .380 AVG, 30 H, 0 HR, 7 RBI, 0 SB

Adachi batted second in most of the games he played in July (twenty-one of twenty-two games) and recorded a hit in eighteen games.

He could return to the active roster for his next start if there are no lingering problems with his back. His next start could either come against Rakuten (two-game series at Sapporo Dome beginning on April 26) or Lotte (three-game series at QVC Marine beginning on April 29).
