Ryu (shoulder) is expected to throw off a mound in the next couple days, Dylan Hernandez of the Los Angeles Times reports. The left-hander has been slowly building strength in his shoulder on flat ground over the past several days, and it sounds like he'll return to mound work shortly. It's uncertain whether he'll throw at full strength in his first bullpen since his mid-September setback, but a successful session would be the first big step toward being cleared for a potential postseason start.
