Cato directed the 38-yard touchdown drive in six plays, finishing with a 17-yard TD strike to Devon Johnson, who was catching his second pass of the season.
MU's defense forced a three-and-out and the Herd followed with a nine-play, 89-yard drive. The big play was Cato's 40-yard toss to Jazz King, and Essray Taliaferro finished with a 4-yard run.
The Herd offense slowed down in the second quarter - indeed, the rest of the contest. An 11-play, 83-yard drive finished with a Steward Butler 1-yard run, giving the Herd a 24-0 lead with 5:05 left in the half. Sean Ianno's field goal - remember, UTSA couldn't score a touchdown despite having first-and-goal from the 7 - set the 24-3 halftime score.
The third quarter was unmemorable, save for safety A.J. Leggett's interception in the end zone on what could have been a 25-yard scoring play. Soza tried to isolate a receiver on linebacker McKelvey, but McKelvey matched him stride for stride and Leggett had excellent position to make the catch.
That, too, kept the Roadrunners from sniffing a change in momentum.
"I was banking on A.J. to be over there," McKelvey said. "I guess they tried to think I was a typical linebacker, put me on an island. I played safety before, so I would know how to play that technique. Hey, we made a play and that's what we're supposed to do."
After Haig kicked a 31-yard field goal to start the fourth quarter, Soza and the Roadrunners woke up for an eight-play, 75-yard drive. Three plays after Soza hit the speedy Kenny Bias for 27 yards on a bubble screen, Soza scored from the 1 to make it 27-10.
That brought a sliver of suspense into the proceedings, which the Herd offense proceeded to squash with its longest TD drive of the season, an 11-play, 74-yard march that burned 5 minutes, 58 seconds. After 10 running plays got the Herd to the UTSA 4, Cato found Demetrius Evans in the middle for the touchdown with 3:46 left.
UTSA (2-4, 1-1) became the 10th Texas-based team to file out of Huntington a loser. Coach Larry Coker was equally impressed with the Herd defense and depressed over his team's offensive outing.
"You can't win with negative plays," Coker said. "That's huge. That's a bad situation. The negative plays are disastrous for anyone - you fall behind on the chains and your defense has a huge disadvantage."
