The 2023 Major League Baseball postseason ran from October 3 to November 1, culminating in the Texas Rangers defeating the Arizona Diamondbacks in the World Series to capture their first championship in franchise history. The field featured notable returns and streaks, including the Baltimore Orioles and Rangers ending long playoff droughts (first since 2016), the Los Angeles Dodgers extending their active record of 11 straight postseason berths, and the Diamondbacks returning for the first time since 2017. Interestingly, all five teams with artificial turf (Miami, Arizona, Toronto, Tampa Bay, and Texas) made the playoffs, and it was the first postseason where the last four remaining teams in the League Championship Series all had 90 or fewer regular-season wins. A historic moment occurred in the Wild Card Series when the Minnesota Twins swept the Toronto Blue Jays, ending their infamous 18-game playoff losing streak—the longest in North American sports history—with Royce Lewis hitting two home runs in Game 1. The postseason drew a total attendance of 1,775,625 across 41 games, averaging 43,308 per game, as the Rangers clinched their title on November 1.
