Grisham (hamstring) participated in "light on-field agility exercises" Saturday and is expected to undergo imaging in New York on Monday, per MLB.com.
Grisham was placed on the 10-day IL on Saturday after straining his right hamstring while running the bases Friday. He felt better Saturday morning, but it's to be determined how much time he'll have to miss, per Greg Joyce of the New York Post. The results of Grisham's imaging Monday should provide a clearer picture of his return timeline.
