Of the eight games played yesterday in the first full day of the NCAA men’s basketball tournament, six of the eight teams to advance were the higher-ranked seeds, but that left room for two early-round upsets in the South bracket: No. 11 seed Dayton beat No. 6 seed Ohio State, and No. 9 seed Pittsburgh dominated No. 8 seed Colorado.
