Ralph Mims added 16 points for the ninth-seeded Seminoles (19-13), who shot 45 percent to win their league tournament opener for the second straight year. Once again, their reward is a quarterfinal matchup with top-seeded North Carolina on Friday.
Jeff Teague scored 15 points to lead Wake Forest (17-13), which trailed almost the entire way after winning both regular-season meetings by an average of 12.5 points.
Rich almost single-handedly put the game away by scoring 15 of Florida State's 17 points -- including 10 straight -- during one 4 1/2 minute stretch midway through the second half.
