Starting in December 2019, baseball fans noticed something different about MLB uniforms. There was a Nike swoosh on the front of every jersey. How did it get there? The swoosh is part of a 10-year deal between Nike, MLB, and Fanatics, a company that sells official fan gear. The deal is worth more than $1 billion. Individual teams will get over $3 million each year. Another reason for adding the swoosh is because Nike is so popular among young people. It’s hoped they will buy more jerseys and come to more games.
