Here is a break down of attendance in Major League Baseball through the end of May.
In spite of on the field success, the Seattle Mariners are down 10.5%. No real surprise here since there is usually a delay in on field success and increase in attendance. Teasing out the Mariners a bit more, expectations were very high last year after missing the playoffs on the final game of the Season in 2014 which led to the increase in attendance early 2015.

Overall MLB Attendance is down slightly year over year but up over the 3 year average.
Toronto Blue Jays, New York Mets, Houston Astros and Chicago Cubs are riding the success of last year’s playoffs to lead the league in year over year increase.
