Adrian Martinez got another turn at quarterback for the Birmingham Stallions on Saturday night, and did he ever make the most of it.

While Martinez’s passing numbers were modest in the Stallions’ 32-9 victory over the Houston Roughnecks, the quarterback ran for 138 yards on nine carries and directed the Stallions to scores on six of their eight full possessions at Rice Stadium in Houston.

At 5-0, Birmingham has the only undefeated record in the United Football League. The Stallions extended their winning streak to 12 games. Birmingham’s last loss was so long ago that Houston was called the Gamblers when it defeated the Stallions 27-20 on May 13, 2023.

Martinez had three runs that gained at least 30 yards on Saturday night. The biggest might have been the first.

With Birmingham facing third-and-14 at the Houston 40-yard line on its opening possession, Martinez scrambled for 31 yards to set up the first of running back Ricky Person Jr.’s two touchdowns runs. He scored from 6 yards out with 8:44 left in the first half.

Martinez had runs of 30 yards and 34 yards on drives that ended in field goals by Ramiz Ahmed for the only points of the second half.

Birmingham punted on its second possession, then had three straight touchdown drives before halftime, with Larry Rountree III scoring on a 5-yard run and Person scoring on a 2-yard run 8:20 apart in the second quarter.

In between, Martinez threw a 27-yard touchdown pass to tight end Jace Sternberger. Martinez completed 11-of-20 passes for 155 yards with one touchdown and no interceptions. He had a pass dropped in the end zone on the first possession of the second half.

Birmingham alternated Martinez and Matt Corral at quarterback in two-possession increments during its first two games. Martinez took over the offense during a 33-14 victory over the Memphis Showboats in Week 3. Corral was back under center for Week 4′s 20-18 victory over the D.C. Defenders.

Former South Alabama tight end Braedon Bowman scored Houston’s touchdown on a 1-yard pass from quarterback Reid Sinnett with 11 seconds left in the first half.

The outcome might have been more competitive looking, but Nevelle Clarke intercepted Sinnett in the end zone and the Birmingham defense stopped the Roughnecks on downs twice.

JoJo Tillery also had an interception for the Stallions, but the safety’s sprint down the sideline toward a touchdown was cut short when he sustained what appeared to be a hamstring injury.

The loss left Houston at 1-4.

Birmingham plays the Memphis Showboats at 11 a.m. CDT Saturday at Simmons Bank Liberty Stadium in Memphis in its next game. ABC will televise the contest.
