Jan. 21—ATLANTA — Ohio State claimed its ninth national championship with a 34-23 win over Notre Dame on Monday night at Mercedes-Benz Stadium.The Buckeyes finished the first half on a 21-0 run to take a two-touchdown lead into the locker room at halftime then held off the Fighting Irish in the second half.Notre Dame got the opening kickoff and put together the exact type of drive the Fighting Irish likely expected to need to win the game.They used 18 plays to go 75 yards and take 9:45 off the clock before Riley Leonard scored from 1 yard out.
