Ryu (shoulder) threw 20 pitches from a mound Sunday, Dylan Hernandez of the Los Angeles Times reports. Ryu was limited to just fastballs, but one would expect he'd add breaking pitches to the mix within the next session or two. With no setbacks having been reported yet, the left-hander remains on track for a mid-to-late May return.
