Arkansas (2-4, 1-2 Southeastern Conference) had been blasted by a combined score of 110-10 in its first two league games.
The Tigers (1-4, 0-3) were left at the bottom of the SEC West after a second-half quarterback change failed to provide much of a spark to an offense that committed five turnovers.
Tyler Wilson completed 20 of 27 passes for 216 yards. The Razorbacks scored two touchdowns in the fourth quarter to pull away before Auburn scored again in the final minutes
Auburn coach Gene Chizik replaced struggling starter Kiehl Frazier with Clint Moseley in the second half, seeking a spark for a sputtering offense. Moseley threw a pair of interceptions in the end zone during the fourth.
