Nageru na utsu na kettobasu nai
Futsuu no booru ja nai n' da zo
Hitori de nan demo dekiru n' da

Korokoro piyoyon pyunpyururun
Tonde hazunde korogatte
Sono ki ni nareba aoi sora
Mienaku naru made HOME RUN!!

Ball boy! (Ball boy!) Ball boy! (Ball boy!)
Fighting ball!

Modoru na iku na _tobidasu nai
Marumaru booru de korobu kedo
Te wo dashi ashi dashi fumbareru

Byunbyun gagagan pyoropyororon
Hi no naka chi no naka mizu no naka
Poozu wo kimete nikkori sa
Kimi no kokoro ni STRIKE!!

Ball boy! (Ball boy!) Ball boy! (Ball boy!)
Fighting ball!

Warau na naku na fuzakeru nai
Karada wa booru de chibi da kedo
Kokoro wa ooki na hi no tama da

Pompom bababan gyungyururun
Doro ni mamirete yogorete mo
Kokoro wa itsu mo shiroi maru
Ooki na yume mite PLAY BALL!!

Ball boy! (Ball boy!) Ball boy! (Ball boy!)
Fighting ball!
