After being called up to the majors from the then-Dodgers' double-A affiliate San Antonio Missions, Beltré made his major league debut on June 24, 1998, starting at third base in the first game of an interleague series against the Anaheim Angels. At the time, he was the youngest player in the National League (NL). During his first at-bat, Beltré hit a two-out run batted in (RBI) double off Angels starter Chuck Finley into left field to score Paul Konerko from second base to tie the game. Beltré hit his first home run six days later against Texas Rangers starter Rick Helling. At the end of the 1998 season, Beltré finished with 13 errors at third base while batting .215 with seven home runs.
