Caleb Kilian returned to the mound for Triple-A Iowa on Sunday and pitched two scoreless innings out of the pen.

Kilian was injured in his first start for Iowa this season and then got released and re-signed to a minor league deal by the Cubs. Interestingly, he was up to 97.0 mph on average with his fastball in his first game back, topping out at 98.7 mph. Last year, he averaged 93.6 mph in one start and one relief appearance for the Cubs. He could turn into a quality major league reliever if he can stay healthy and maintain that kind of velocity.
