The Yomiuri Giants at home Hero Award for June went to Yuki Koyama (determined by fan balloting).
June 7, vs Lotte: Koyama recorded the first complete game of his career. He managed to keep a shutout going through eight full, despite struggling on and off throughout the game. He allowed a run in the 9th on a single and a double, and had runners on first and second with no out at one point, but was able to bear down and retired the next three hitters in a row for the complete game. The Giants won, 8-1. [official announcement - box score]
