Ku sii qor faqradan - Kadib labo sano oo tartan adag iyo ciyaartoy weerar ah, National iyo American Leagues waxay sameeyeen nabad, iyo, sida qayb ka mid ah heshiiska, dhowr lammaane oo kooxood ah ayaa loo qoondeeyay ciyaaraha bandhigga ee isdhexgalka ka dib xilli ciyaareedkii 1903. Taxanahan waxaa soo qabanqaabiyay naadiyada ka qeyb galaya, sida ciyaarihii Taxanaha Adduunka ee 1880-meeyadii. Mid ka mid ah waxay la jaanqaadeen labada guuleyste ee pennant, Pittsburgh Pirates ee NL iyo Boston Americans (oo markii dambe loo yaqaanay Red Sox) ee AL; midkaas waxaa loo yaqaan '1903 World Series'
waxaa lagu ciyaaray Huntington Avenue Grounds. Waxaa horay u soo diyaariyay labada milkiile, maadaama labada kooxoodba ay ahaayeen hogaamiyayaal horyaal oo leh kala duwanaansho ballaaran. Boston waxay Pittsburgh ku jabisay shan kulan ilaa seddex, iyagoo ku guuleystay qoto dheer oo ka dambeeya Cy Young iyo Bill Dinneen iyo taageerada kooxda Royal Rooters. Horyaalka ayaa sharaf weyn u soo kordhiyay Boston wuxuuna cadeeyay in horyaalka cusub ee American League uu ka adkaan karo National.
