The penalty? A one-year postseason ban.March 26, 2020: It’s Opening Day for all 30 teams. Did spring training provide enough time for 30 managers to adjust to the new three-batter minimum for all pitchers? Sure. Among those cut from major-league rosters in spring training: Oliver Perez, Andrew Chafin, Alex Claudio and Adam Kolarek, all of whom had valuable roles in the 2010s but struggled to adjust to baseball’s new LOOGY-less reality.

Parking spaces are scant, so Lyft assumes naming rights and becomes the preferred method of transportation to and from the ballpark.July 5, 2026: The San Diego Padres’ Manny Machado completes the 16th unassisted triple play in major league history, and the first ever by a third baseman.July 25, 2027: Mark McGwire, Barry Bonds and Roger Clemens are officially inducted into the Baseball Hall of Fame, having been chosen by a veterans’ committee the previous December. Their plaques do not include an asterisk.Sept. 30, 2027: Christian Yelich, 35, wins his 10th consecutive batting title, breaking Ty Cobb’s all-time record. The accomplishment passes quietly, as batting average is now considered a fringe statistic.Aug. 7, 2028: Mike Trout hits his 600th career home run on his 37th birthday. He’s the only player to hit a home run on eight different birthdays, an all-time record. Two years remain on his contract after the season. Improbably, he never receives an endorsement opportunity from Jersey Mike’s subs.June 1, 2029: Bryce Harper, 36, hits his 600th career home run. Two years remain on his contract after the season.

Pujols, 41, officially retires the following week.Nov. 18, 2021: MLB and the MLB Players’ Association ratify a new collective bargaining agreement.

Javy Baez, Corey Seager, Francisco Lindor, Carlos Correa and Trevor Story all leave for greener pastures as free agents.
