Mayfield completes 19 of 20 as No. 7 Oklahoma tops UTEP 56-7

NORMAN, Okla. -- With such efficiency in his head coaching debut, there's no telling what's in store for Lincoln Riley's Oklahoma Sooners . Baker Mayfield missed just one pass and threw for 329 yards and three touchdowns in one half of work to help No. 7 Oklahoma roll past UTEP 56-7 on Saturday. Mayfield completed 19 of 20 overall. He connected on 16 straight to start the game and didn't miss until just under four minutes remained in the second quarter. "I need to complete it," Mayfield said. "We've got a long way to go. We had guys open today. Not just that one incompletion -- that first ball to Mark Andrews that he had to jump up to get, that should be an easy touchdown. So, room for improvement." The Sooners made the 33-year-old Riley look like a seasoned veteran. He was promoted from offensive coordinator after Bob Stoops abruptly stepped down in June.
