LOS ANGELES -- Pitcher Hyun-Jin Ryu threw about 40 pitches in the bullpen before Sunday's game with the Colorado Rockies and said he felt no discomfort in his left shoulder, which has been sore enough to keep him off the mound since Sept. 12."Everything worked pretty well," Ryu said through his interpreter. "It was a very positive result."The next step is for Ryu to pitch a simulated game Wednesday at Dodger Stadium.
