Major League Baseball (MLB) is set to open the 2021 season today. Following an unprecedented season with no fans attending any 2020 regular-season games, MLB is welcoming fans back to ballparks under local government laws and with health and safety protocols in place. MLB's total attendance for the 2019 season was 68,494,752, as the league continued its trend as being the highest-attended professional sports league in the world. Players from more than 20 countries and/or territories will be on #openingday rosters. #Globalsport #globalgame
