Reason Behind Fan Flow to Ballpark This Season

One of the crucial reasons for the increase of fans in the stadium is the Mariners winning percentage this season is .538. It has certainly pushed their fans to the stadium to cheer up their team and put pressure on opponents.

2023 is likely to reverse the trend of declining attendants after several years as it has lost its high crowds, which it used to be. Attendance has been increasing in most of the MLB stadiums, including T-Mobile Park. 

 The recent new rules that have been applied by the league help to shorten the game. It has resulted in the arrival of fans to the stadium. Some of those reasons are:

  • The addition of a pitch clock 
  • Ban on radical shifts
  • The limited pitcher throws to first base when a runner is on it, and bigger bases drive more action helping to remove pauses.  

These new rules have saved time. Games have taken 26 minutes less on average through July 9 than in 2022. Similarly, games are completed in 32 minutes less than they did in 2021. 

Furthermore, concerns about pitch clock breaches influencing game results have been raised. It resulted in only 12% of the games with contraventions, while 60% of them do not experience any violations.  

The average time to complete a game in the 2021 season is 190 minutes and was 184 minutes in the 2022 season. This average time has plummeted to 158 minutes in the 2023 season, which is less than 32 minutes and 26 minutes than that of seasons 2021 and 2022.
