Hisashi Iwakuma (RAK) started yesterday's game for the Rakuten Eagles and tossed a solid 8 innings while giving up 2 runs (both earned) on 7 hits and 2 walks. He also struck out 7.
According to Sponichi, the Yanks, Indians, SF Giants, and Phillies had scouts at the game. And it seems the Eagles would be willing to listen to Iwakuma should he want to discuss the possibility of posting.
Sanspo mentions that a total six clubs were at the game.
