Yes, postseason stats do count in career stats in Major League Baseball (MLB). All postseason games, including the Wild Card game, Division Series, League Championship Series, and World Series, are counted as part of a player’s career statistics.
Postseason statistics are typically kept separate from regular season statistics, but they are included in a player’s overall career numbers. For example, a player’s total hits, home runs, RBIs, and other statistical categories will include both regular season and postseason numbers.
Postseason statistics can have a significant impact on a player’s overall career numbers, as some players have put up impressive numbers in the postseason and have helped their teams win championships. For example, Derek Jeter, a former shortstop for the New York Yankees, is known for his exceptional postseason performance, and his career postseason numbers are a big part of his legacy as one of the greatest players in baseball history.
Overall, postseason statistics are an important part of a player’s career record in MLB, and they are counted alongside regular season statistics in a player’s career totals.
