Orion Kerkering Injury: Getting back on mound Saturday

Kerkering (hamstring) will throw a bullpen session Saturday, Charlotte Varnes of The Athletic reports.

It will be his first time throwing off a mound since he suffered a Grade 1 hamstring strain. If things go well Saturday, Kerkering would likely then progress to facing hitters before appearing in a game. The right-handed reliever has plenty of time to ramp up for Opening Day, barring setbacks.
