<P> The 1990 World Series was the 87th edition of Major League Baseball 's championship series and the conclusion of the 1990 Major League Baseball season . The Series featured the defending champions and heavily favored American League ( AL ) champion Oakland Athletics against the National League ( NL ) champion Cincinnati Reds . The Reds defeated the Athletics in a four - game sweep . It was the fifth 4 - game sweep by the National League and second by the Reds after they did it in 1976 , as well as the second consecutive World Series to end in a sweep , after the A 's themselves did it to the San Francisco Giants in 1989 . It is remembered for Billy Hatcher 's seven consecutive hits . The sweep extended the Reds ' World Series winning streak to nine games , dating back to 1975 . This also was the second World Series meeting between the two clubs ( Oakland won four games to three in 1972 ) . As of 2017 , this remains both teams ' most recent appearance in the World Series . </P>
