ROCHESTER, Mich. (AP) -- Hanna Reising scored 23 points and Jessica Pike added 20 as Oakland shocked Florida State (No. 22 ESPN/USA Today, No. 21 AP) 85-75 on Sunday.
Florida State (6-2) trailed by as many as 19 points in the second half but got as close as 77-73 with 4:37 remaining. But Oakland (4-2) scored eight of the game's final 10 points to finish off the upset.
A Pike basket extended the lead to 82-75 before Reising capped the win with two free throws with 30.1 seconds remaining.
Tanae Davis Cain led the Seminoles with 16 points.
Oakland, which doesn't have a starter taller than 5-foot-11, outscored Florida State 40-30 in the post while also holding a 37-35 rebounding edge against their third ranked opponent this season.
"I think [not being intimidated in the post] is one of the benefits of playing the schedule we play," said Oakland coach Beckie Francis, whose team lost earlier to Georgia (No. 8 ESPN/USA Today, No. 7 AP) and Auburn (No. 20 ESPN/USA Today, No. 18 AP).
The Golden Grizzlies led 48-31 at halftime after Reising beat the first-half buzzer with a 3-point field goal. Mara Freshour, who scored 14 points along with teammate Jacinta Monroe, hit a 3-pointer with 11:59 remaining to trim Oakland's lead to 62-54.
"We didn't take advantage of our size inside," Seminoles coach Sue Semrau said. "We're not ready as a defensive basketball team to be spread out the way we were."
