Fantasy baseball's Week 4 begins with a celebration of Jackie Robinson Day, honoring the day (April 15) on which Robinson made his big league debut in 1947. All 15 teams are scheduled to play Monday in commemoration of the occasion.

That lines up every team for at least six games, and 10 teams are scheduled to play seven times: The Arizona Diamondbacks, Boston Red Sox, Chicago Cubs, Cleveland Guardians, Detroit Tigers, Los Angeles Angels, Miami Marlins, San Francisco Giants, Tampa Bay Rays and Texas Rangers.

Monday is also Patriots' Day in Boston, which means the annual morning Red Sox game coinciding with the occasion. This season, the Red Sox host the Guardians with a scheduled 11:10 a.m. ET start time, and the weather is projected to be clear for baseball that morning. Prepare accordingly in your fantasy baseball leagues.

Week 4 brings the Atlanta Braves to Houston's Minute Maid Park, site of their clinching the 2021 World Series, for the first time since that game, as the Braves and Houston Astros play a week-opening three-game series. Max Fried, who won the Game 6 clincher in Houston, is scheduled to start the series finale Wednesday.

We'll see the season debuts of the Arizona's Jordan Montgomery and Michael Lorenzen of the Rangers during Week 4. Montgomery made his final rehabilitation start for Triple-A Reno on April 13, after which the Diamondbacks announced that April 19, the Friday of Week 4, will mark his first start for the big club. Lorenzen made his final rehab start for Triple-A Round Rock on April 10, lining him up for a two-start Week 4 with road starts against the Tigers (Monday) and Braves (Saturday).
