The Chiba Lotte Marines invited the band from nearby Narashino High School to sit in left field and power their cheering section on Friday night.
Turns out, the kids ended up helping to provide the perfect soundtrack for an entertaining pitcher's duel between 20-somethings Yuya Yanagi and Kota Futaki.
The Chunichi Dragons' Yanagi went the distance in a 13-strikeout gem, Dayan Viciedo made the Chiba Lotte Marines pay dearly for a ninth-inning error with a tiebreaking single and the Dragons earned a 4-1 win at a sold-out Zozo Marine Stadium.
