Kriske (shoulder) began a throwing progression Thursday, MLB.com reports.
Kriske landed on the injured list May 13 due to a right shoulder impingement and had previously been shut down from throwing. Beginning a throwing progression is a step in the right direction, though it's just the first of many as the right-hander works his way back to full health. Having been transferred to the 60-day injured list June 2, Kriske isn't eligible to be activated until after the All-Star break.
