Promotion play-offs. Now… this is a bit mysterious: it looked like that the winners of the 2 Zones would be directly promoted. But apparently the top 2 teams in the each Zone went to further play-offs and in them
Magallanes finished 2nd and was directly promoted.
Santiago Wanderers most likely 3rd in the this strange stage went to promotion play-off against the 14th in the First Division – Union San Felipe. The match was played in Vina del Mar on February 24, 1990, and ended without a winner, but in the extra tile Santiago Wanderers destroyed their opponents – 4-1 – and went up. Or rather returned to First Division, which was wonderful.
Universidad de Chile won the 1989 Second Division title and was promoted of course. Quick return to top flight, after a single season in the the second level.
