Kelliher, who attended Lake Stevens High School in Washington, is committed to play baseball at the University of Oregon.
"I'm still in the 50-50 range," Kelliher told The Herald of Everett, Wash., regarding his decision of whether to go to college or turn pro. "Oregon is a great school and I'd love to go there. And it'd be fun to stay in the Northwest. I'll definitely consider any offer made to me. Pro ball is a big deal. It's a once-in-a-lifetime thing."
Perfect Game touted Kelliher as the No. 1 high school prospect in Washington and the No. 39 right-handed pitcher in the nation.
He went 5-1 this season to lead Lake Stevens to a league title.
