Explanatory notes

(Regular season winning percentages in parentheses.) Boldfaced scores indicate the winning team. Underlined scores denote extra-inning games. Olive-shaded score boxes denote games won by the VISITING team. Higher-seeded teams (those with the initial home field advantage) are shown on the BOTTOM side in each matchup. However, beginning with 2012, each league has TWO wild card teams, competing in a one-game "play-in," and whichever of those two teams that wins in each league is displayed below (after the outcome is known), so as to properly align with the subsequent divisional series scores. Beginning in 2003 and continuing through 2016, the league that won the All Star Game got the initial home field advantage in the World Series; prior to 2003, initial home field advantage in the World Series alternated from year to year. Except for 2002 (the infamous tie), the American League won the All Star Game every year between 1997 and 2009. Beginning in 2017, home field advantage in the World Series goes to the team with the higher regular season winning percentage.
