When Does MLB Season Start? 2023 Opening Day, Schedule and Important Dates


The 2022-23 MLB offseason was a wild one highlighted by megadeals, contract drama and brazen spending by the New York Mets.

With the offseason nearly over, however, and Spring Training just around the corner, fans are eagerly awaiting the start of baseball season. It won't be long before ballparks are full again and their favorite players return to the diamond on Opening Day.

Here's everything you need to know about the 2023 MLB schedule as the season prepares to get underway.

When Does 2023 MLB Season Start?

There's a bit of a wrinkle in the preseason schedule this year because of the World Baseball Classic, which is essentially baseball's version of the Olympics. The WBC will take place over a two-week span from March 8-21, during which time many MLB players will leave their teams to play in the global tournament.

Accordingly, players participating in the WBC will report to camp a few days before the rest of their teammates. Pitchers and catchers in the tournament are expected to report on Feb. 13, while pitchers and catchers not in the tournament will arrive a few days later from Feb. 15-17 depending on the team. Meanwhile, position players in the WBC will report to camp on Feb. 16, while position players not in the WBC will arrive on Feb. 20 or 21.
