What Is 1998 American League Division Series

Overview

The 1998 American League Division Series (ALDS) marked the opening round of the American League postseason, determining which two teams would advance to the American League Championship Series (ALCS). As part of Major League Baseball’s playoff format since 1995, the ALDS featured best-of-five matchups between division winners and wild card teams.

This year's series were particularly significant due to the dominance of the New York Yankees, who finished the regular season with 114 wins—the most in franchise history at the time. The matchups included the Yankees vs. the Texas Rangers and the Cleveland Indians vs. the Boston Red Sox, both teams having strong offensive lineups and postseason experience.

• Yankees–Rangers series: The New York Yankees swept the Texas Rangers in three straight games from September 29 to October 2, outscoring them 32–11.
• Indians–Red Sox series: The Cleveland Indians defeated the Boston Red Sox 3–1, with Game 4 ending in a dramatic 2–1 victory on October 5.
• Yankees' dominance: New York won Game 1 of their series 2–0 behind David Wells’ complete-game shutout, setting the tone early.
• Key performance: Indians' slugger Manny Ramirez hit .389 with two home runs and six RBIs during the series against Boston.
• Postseason format: The ALDS was introduced in 1995 after MLB realignment created three divisions and an additional wild card team.

How It Works

The American League Division Series is structured as a best-of-five playoff to determine which two teams advance to the American League Championship Series. The matchups are determined by seeding based on regular-season records and division standings.

• Best-of-five format: The first team to win three games advances; all series follow a 2–2–1 home-field structure.
• Seeding: The division winner with the best record hosts Games 1 and 2, with the higher seed having home-field advantage.
• Wild card team: The non-division-winning team with the best record qualifies as the wild card and enters the ALDS.
• Home-field advantage: In 1998, the Yankees had home-field due to their 114–48 record, the best in MLB.
• Game scheduling: Games are played consecutively, typically starting September 29, with travel days built in for cross-country matchups.
• Officiating: Each game uses four umpires on the field, with replay review not available until decades later.
