Entering Wednesday, 121 of the 122 current major professional sports franchises had finished in sole possession of last place in their division at least once since the start of 1984. On Wednesday night the single outlier had its longest streak of nonfutility in pro sports snapped as the Cincinnati Reds clinched last place in the NL Central.

Cincinnati’s stretch of avoiding the cellar was the longest active streak across the four major sports leagues. That distinction will now belong to the San Antonio Spurs at 28 straight seasons. The NFL's longest active streak is the Steelers' 26 straight seasons. The NHL's longest belongs to the Red Wings, 24 straight.
