Perfect game in Japan Series finale

There was a combined perfect game thrown in the finale of the Japan Series.  The starter, Daisuke Yamai pitched 8 IP and Hitoki Iwase threw the final inning.  Score was 1-0, clinching the series for the Chunichi Dragons over the Hokkaido Nippon Ham Fighters.  The only run scored on a sac fly.  

Now that the series is over, eligible players have 10 days (until 11/12) to file for free agency.  Fukudome, who happens to play for Chunichi but evidently still is hurt, is expected to file Monday (today).  Iwase, who would likely draw a lot of interest from MLB clubs, also is eligible, but it is uncertain whether he wants come to MLB.
