Joe Harris matched a season high with 20 points, and No. 6 Virginia pulled away to beat Florida State 64-51 on Friday in an Atlantic Coast Conference tournament quarterfinal.

Anthony Gill added 16 points for the top-seeded Cavaliers (26-6).

They shot 48 percent, forced 15 turnovers and earned their third double-digit victory over the Seminoles this season while reaching the semifinals for the first time since 1995.

Okaro White scored 17 points and Aaron Thomas added 13 for the ninth-seeded Seminoles (19-13).

They shot 43 percent against one of the nation's best defenses but couldn't keep the Cavaliers off the boards when it counted most, and were denied their third victory over a top-seeded team since 2009.

Virginia held a 31-25 rebounding advantage — 21-13 in the second half and finished with 17 second-chance points.
