Kenny Hill had 322 yards of total offense playing only the first half, Jeremy Tabuyo turned two short passes into touchdowns and sixth-ranked Texas A&M rolled to a 58-6 victory Saturday at SMU.
Trey Williams ran for two touchdowns for the Aggies, who last started 4-0 in 2006.
The Mustangs (0-3) played for the first time since coach June Jones resigned only two games into his seventh season.
Hill, the thrilling sophomore who succeeded 2012 Heisman Trophy winner Johnny Manziel as the starting quarterback, completed 16 of 22 passes for 265 yards with two touchdowns and his first interception at Texas A&M. His 58-yard run set up another touchdown as the Aggies built a 38-3 halftime lead in SMU's home opener.
Tabuyo had a 30-yard TD from Hill, and a 50-yarder from Kyle Allen in the third quarter.
