Kevin Sumlin’s homecoming was a dud.
Returning to Houston, where his head-coaching career began, Sumlin hoped to turn around an Arizona Wildcats season that started slowly.
Instead, Arizona took a step backward.
The Wildcats lost to the Cougars 45-18 in front of an announced crowd of 32,534 at TDECU Stadium on Saturday.
Arizona is 0-2 for the first time since 1981. BYU beat the UA 28-23 last week.
Khalil Tate, who appeared to be limited after injuring his left ankle or calf in the first quarter, completed 24 of 45 passes for 341 yards.
