Diamondbacks' Zac Gallen: Cleared for throwing

Gallen (hamstring) will begin a throwing progression Tuesday, Theo Mackie of The Arizona Republic reports.

Gallen appears to have his sights set on returning from the injured list when first eligible after being diagnosed with a right hamstring strain Friday. This will be a strong first step toward meeting that goal, and he should be cleared to resume mound work quickly considering he last threw off a mound Thursday.
