Hagen Smith is fine-tuning his mechanics in the Arizona Fall League.

The Chicago White Sox prospect displayed some of his progress Tuesday while pitching for the Glendale Desert Dogs against the Peoria Javelinas. He struck out Seattle Mariners prospect Jonny Farmelo with a 97.5 mph fastball to end a 1-2-3 first inning. He then struck out the side in his second — and final — inning of work.

“I knew I was going to be two innings, so just try to go out and attack the zone,” Smith said during a videoconference call Thursday. “I felt like I got ahead early, which is the plan. And everything went good from there.”

Outings like Tuesday’s have helped the left-hander earn a spot on the AFL’s American League roster for the Fall Stars Game, which will be held Sunday at Sloan Park in Mesa, Ariz.
