Sunday morning offered a good visual measuring stick for Ryu’s progress.At one point he, Brandon Beachy and Brandon League were all throwing in the outfield at Dodger Stadium. Beachy, who is 13 months removed from Tommy John surgery, was easily the most advanced. He was playing long toss from left-center field to the left-field foul line, winding up and throwing from a crow hop.On the other end was League, who is still tossing somewhat leisurely from approximately 75 feet. Like Ryu, there is no timetable for League to return from his shoulder problems.In the middle was Ryu, hurling fastballs and changeups and spinning his curve.“There is no pain right now,” he said. When Hyun-Jin Ryu first experienced shoulder inflammation in spring training, it appeared to be a minor injury. He received an injection and was shut down from throwing for three days.When the inflammation and pain didn’t let up, Ryu was shut down for another two weeks. He didn’t start throwing until early April, about two weeks ago, and still hasn’t received permission to throw off a mound.There is no clearly defined timetable for his return. Ryu said he doesn’t even have a target date to be pitching in games again. How about before the All-Star break?“Of course,” he said through an interpreter. “I have to come back before then. I’m confident about that.” Newsroom GuidelinesNews TipsContact UsReport an Error But the Dodgers’ need for a fifth starter persists. They don’t need one until Friday in San Diego, but manager Don Mattingly said he is contemplating giving Zack Greinke an extra day’s rest and using his fifth starter on Thursday in San Francisco instead.David Huff made a spot start Tuesday against the Seattle Mariners and was subsequently designated for assignment. Scott Baker, Zach Lee, Joe Wieland and Mike Bolsinger are all candidates to be recalled Thursday.Ryu went 14-7 with a 3.38 earned-run average in 26 starts last season, and the Dodgers might miss him more if they were not riding a seven-game winning streak. Ryu said in spring training that he’d like to pitch at least 200 innings this year, something he hasn’t done in his first two major league seasons. That won’t happen now, and Ryu is in no hurry to rush back.“At this condition, I’m sure I could (throw off a mound) at some point,” Ryu said, “but I haven’t gotten far in the long toss yet so we’re just being cautious.”AlsoYasiel Puig (sore left hamstring) was not in the starting lineup for the fourth time in the last five games, but Mattingly said that Puig was available if needed in case of a double-switch. Puig could return to the starting lineup Tuesday in San Francisco. … Carl Crawford (flu) was not available off the bench after receiving IV treatment Saturday night. … Joc Pederson felt he was safe at third base after apparently eluding a rundown in the second inning. The umpires agreed until they discussed the play and overturned the initial call, ruling that Pederson left the baseline. The play could not be challenged. … Pederson is 1 for 4 in stolen-base attempts this season.
