World Baseball Classic fans have their first cult hero of this year's tournament: St. Louis Cardinals outfielder Lars Nootbaar. Nootbaar, who is playing for Team Japan this year, has had his "Grind the Pepper" on-base celebration delightfully performed by a team of Japanese youth ballplayers.After video of the young players made it to Japanese television, it quickly became an international sensation.The Game Day MLB@TheGameDayMLBLARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 2183318LARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 🐐🇯🇵 https://t.co/pIJuRCA9CyNootbaar, a native of El Segundo, California, is playing for Japan in the World Baseball Classic as his team looks for its third tournament title.While he is an American citizen, Nootbaar qualifies to play for Japan as he has a Japanese mother. He will be the first player to suit up for Japan in the WBC who has qualified for the team because of his ancestry rather than being a Japanese native.But none of those officialdoms matter much to these Japanese children, nor does it to anyone around the world taking delight in the video.Sara Sanchez@BCB_SaraThe greatest thing on the internet today. twitter.com/TheGameDayMLB/…The Game Day MLB@TheGameDayMLBLARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 1321LARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 🐐🇯🇵 https://t.co/pIJuRCA9CyThe greatest thing on the internet today. 😍 twitter.com/TheGameDayMLB/…o@OwenVsTheWRLDSt. Louis legend Lars nootbaar is an international sensation.

Nootbaar has hit just .231 through his first two major league seasons.However, the 25-year-old found some added pop in his bat in 2022, hitting 14 home runs in 108 games after hitting five in 58 games in 2021. He's already developed quite a following in St. Louis due to his hard-nosed play, and now his reach has stretched far beyond the American Midwest.Kelsey Burd@kburdtweetsNoot going viral is Japan in less than a week is the most Noot thing ever I am obsessed #stlcards #WBC2023 twitter.com/thegamedaymlb/…The Game Day MLB@TheGameDayMLBLARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 171LARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 🐐🇯🇵 https://t.co/pIJuRCA9CyNoot going viral is Japan in less than a week is the most Noot thing ever I am obsessed #stlcards #WBC2023 twitter.com/thegamedaymlb/…Alex@noarsonalexWelcome everyone to Noot Nation!! twitter.com/thegamedaymlb/…The Game Day MLB@TheGameDayMLBLARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 2322LARS NOOTBAAR AND HIS GRIND THE PEPPER CELLY HAVE GONE INTERNATIONAL 🐐🇯🇵 https://t.co/pIJuRCA9CyWelcome everyone to Noot Nation!! twitter.com/thegamedaymlb/…Ghabriel@thestlcardsfan4This is fucking nuts.
