The Lady Hornets got a free throw from Keke Daggs at the 3:27 mark, starting a 10-2 spree that gave the visitors a 14-6 advantage.
A bucket by Kelsey Neal at 4:41 of the second frame pulled Miami to within five, but Vinita scored the final 14 points of the half to open up a 30-11 advantage.
The Lady Hornets outscored MHS 23-7 in the third quarter to push their lead to 53-18 heading into the final stanza. Miami got five of its seven points in the first 2:26 of the quarter, got a bucket from Alyssa Johnson at 3:15 then went scoreless the rest of the way.
