The Ringer: MLB quietly installed a humidor at Fenway Park

. (Another complication: MLB quietly installed potentially exit-speed-suppressing humidors in Fenway Park, Citi Field, and T-Mobile Park prior to this season, extending a list of humidor-equipped parks that previously included Coors Field and Chase Field.) In addition, the aerodynamic drag of the ball has reportedly increased to 2018 levels, which wouldn’t affect exit velocity but would cause batted balls to slow down faster and carry less far.
