Thompson (lat) has progressed to throwing from 100 feet on flat ground, Daniel Guerrero of the St. Louis Post-Dispatch reports.

EDGE Analysis

Thompson was diagnosed with a left lat strain in early March and will require a standard spring training buildup before he's ready for games. The left-hander was shifted to the 60-day injured list Monday, so he won't be eligible for activation until late May. Thompson is likely to be assigned to Triple-A Memphis once he's healthy.
