It has been reported for months that the CF hill & flagpole at Minute Maid Park will be going away next season, and the fence moved in; per a radio report this morning, the Astros run in the postseason this year resulted in too little time to make the change in time for the start of next season, so it will stay for at least one more year.
Not only that, but if the Astros keep making long runs in the playoffs every year, there may not be time to make the changes until a season when they don't make the playoffs.
