CREATE TABLE table_45505 ("Res." TEXT, "Record" TEXT, "Opponent" TEXT, "Method" TEXT, "Event" TEXT, "Round" FLOAT, "Time" TEXT, "Location" TEXT)

Can you tell me the Opponent that has the Round of 3?
SELECT "Opponent" FROM table_45505 WHERE "Round" = '3'
SELECT "Opponent" FROM "table_45505" WHERE "Round" = '3'
