Shortened MLB Season Slated To Begin Around July 24

The MLB season is set to start on July 24th after a long dispute between the players union and the league. The union initially voted against a 60-game season plan, but Commissioner Rob Manfred imposed it due to the pandemic. This season will feature unique changes, such as teams playing only within their geographical divisions and the designated hitter rule applying to both leagues. Players will undergo frequent COVID-19 testing, and no fans will be allowed in stadiums. Teams have expanded rosters and a taxi squad to manage potential COVID-19 cases.

What measures are being taken to ensure player safety regarding COVID-19?
