SAN DIEGO — A day after signing a national of letter of intent to play college baseball in Illinois, San Diego pitcher Mateo Saenz was seemingly untouchable in the Texas high school playoffs.

The big lefty, now committed to play junior college baseball at South Suburban College in Oak Forest, Ill., threw a no-hitter in a 9-0 victory against Santa Rosa in a one-game playoff Thursday at San Diego High School. The bi-district victory sends the Vaqueros to the area playoffs to face what winner of Goliad or Natalia next week.

Through seven innings, Saenz, a senior, struck out 13. He also didn’t allow a walk. The Vaqueros did have one error.

The Vaqueros’ stellar defense allowed for the team’s bats to come around. San Diego totaled 11 hits. Anthony Perez was 2-for-3 with two runs. Romeo Ramirez was 2-for-3 with a run and an RBI and Ariel Salaiz was 2-for-2 with a run. Christian Alvarez and Saenz had two RBIs each. Derrick Gonzalez and Sergio Guerra also had RBIs.

San Diego took a 2-0 lead in the first inning behind RBIs by Gonzalez and Saenz. The fifth inning is when the Vaqueros put the game away. They scored runs on a double by Guerra, a single by Ramirez and an Alvarez triple. They also scored on a single by Anthony Perez.

The Vaqueros scored two more in the bottom of the sixth.
