Long time Seibu Prince Rabbit (well, the team was named Kokudo before) and former NHLer Joel Prpic threw out the ceremonial first pitch (with a nifty intro video) at Seibu Dome where group company team and Daisuke Matsuzaka’s former team the Saitama Seibu Lions play. The event happened two weeks ago on 10 September before the game against the Hokkaido Nippon Ham Fighters, so this is way after the fact, but it’s a fun video nonetheless.
This promotional gimmic seemed to have gone fairly unnoticed (well, the stadium was more than half empty at the time too) because the Rabbits season opener against the Nikko Ice Bucks at their home Dydo Drinko Arena in Higashifushimi only drew 1475 spectators, well below capacity with lots of empty seats.
