Attendance is roughly flat this year across MLB: The league has averaged 29,340 fans per game so far, compared to 29,290 through the same period in 2014. The trend varies considerably by team, however.
Weather and schedule can affect the data so early in the season, but a few patterns are evident. The Royals, fresh off a surprising run to the World Series, have the league’s fastest-growing crowds, rising to 32,000 fans per game from 21,000. Other risers include the Nationals, Padres, and Mariners, who made moves over the offseason and/or entered the season with high expectations. On the other side, teams losing the most fans include the Yankees, Rangers, Phillies, Braves and Rays, which entered the year in decline (though some have been successful so far).
