Calallen High School senior Robert Zastryzny signed a letter of intent during a ceremony last week to attend the University of Missouri in 2010.

Zastryzny is a pitcher for the Calallen Wildcats varsity baseball team.

"He's been playing since tee ball," mother Susan Zastryzny said. "He's been playing tourney-ball since he was 10."

Susan said that Calallen baseball head coach Steve Chapman arranged the Dec. 1 ceremony.

"He wanted to celebrate one of his kids signing with one of the Big 12 schools," she said.

Susan said that Zastryzny had fielded offers from several schools, but decided on the University of Missouri because he wanted to attend a competitive program.

"He's been a pitcher since he was 10," she said. "He wants to pitch where the toughest competition is and Missouri is a Division One school, so it's very competitive."

Susan said that while her son enjoys playing baseball, he has also played many other sports including basketball, soccer, football and was even on the swim team.

"As soon as he got to (the tenth grade) he started focusing on baseball," she said.

While Zastryzny is signing the letter of intent now, he still has the rest of his senior year of high school to attend, as well as another season with the Wildcats, his mother said.

"(College) is a ways away, so I think he's not really thinking too much about it yet," Susan said.

Susan said she was proud of her son and looks forward to his future.

"Kids do stuff and you go watch and you're proud of them," she said. "I'm happy for him, but I was just on the sidelines. He did all the work."
