MLB slate includes regular-season games in Tokyo, London and Mexico

NEW YORK -- Major League Baseball said all 30 teams will start the 2019 season on March 28, the earliest Opening Day in history, excluding international openers.

The previous earliest Opening Day was March 29 of this year.

MLB released the 2019 schedule Wednesday. It will begin with the opening series in Japan between the Seattle Mariners and host Oakland Athletics at the Tokyo Dome on March 20-21.

The 2019 season will be the second under the scheduling format agreed to as part of the 2017-2021 basic agreement. That format adds an additional weekend at the beginning of the season and gives each team three to four additional off days throughout the season to provide added rest and opportunities for rescheduling.

The Boston Red Sox and New York Yankees will play the first-ever MLB games in Europe -- June 29-30 in London.

There will be six games played at Estadio de Beisbol Monterrey in Monterrey, Mexico, starting with spring training games between the Colorado Rockies and Arizona Diamondbacks on March 9-10.

In the regular season, the Cincinnati Reds will host the St. Louis Cardinals on April 13-14, and the Los Angeles Angels will play the Houston Astros on May 4-5.
