Even though the 2020 Major League Baseball season doesn’t officially begin until July 23-24, the league released the schedule for the 2021 season Thursday morning.

Usually the league doesn’t release the schedule until September. But these are different times.

Mariners coronavirus testing: Three positives and lots of speculation, but Jerry Dipoto is encouraged

Per a news release, all 30 major league clubs will play on Thursday, April 1. The 2021 season will mark the fourth consecutive season in which all 30 clubs are scheduled to play on the traditional opening day. If there are no postponements due to weather or extenuating circumstance, it could become the first season since 1968 in which every team across the majors plays its first game of the season on the same day.

The Mariners will open the season at home with a three-game interleague series vs. the San Francisco Giants. It’s part of six-game homestand that has an unusual Sunday off day and three games vs. the White Sox on April 5-7.
