Freshman guard Keaton Wallace led all scorers with 22 points Sunday as UTSA opened its season with a 92-59 victory over East Central, Oklahoma.
The Roadrunners shot 47.1 percent from the field and held the Tigers to 32 percent.
East Central is coming off a 25-8 season and an NCAA Division II Central Regional semifinal appearance. Division I UTSA is trying to improve on a 14-19 record from last year.
The availability of freshman center Adrian Rodriguez for a game Wednesday night at Texas State is in question after he injured his left knee in the second half.
