Who is the athlete who roots for the Guardians?
LeBron James is the one athlete on record as a Guardians fan, and the claim comes from an outlet, not from his own words. CNN reported on October 24, 2016, that "With the Cleveland Indians in the World Series, LeBron James now says he's a fan." The team went by the Indians then and is now the Cleveland Guardians.
Does it line up with where he is from?
James was born on December 30, 1984, in Akron, Ohio, and went to St. Vincent–St. Mary in Akron. His career has included two stints with the Cleveland Cavaliers, along with time with the Miami Heat, the Los Angeles Lakers and the Philadelphia 76ers. Akron and Cleveland are both in Ohio, so the team he was reported to be rooting for plays in his home state and in the city where he has spent part of his NBA career.
