The fifth inning brought up a two-out, none-on situation, and Matt Kemp blasted an 88 mph pitch into the left-field gap and against the wall. He scored when Yangervis Solarte hit a wicked single down down the left-field line.That preceded another episode of Yasiel Puig Live (YPL), in which the rightfielder admired Alex Dickerson’s savage liner until it sailed over his head. Puig followed it up with one of his throws to nowhere, and the Dodgers trailed 6-0 when manager Dave Roberts brought the hook for Ryu.“His velocity started dropping right there, but I think it was just fatigue,” Roberts said of Ryu. “We’d hoped for more and better from him, but to see him out there was great. We’ll know more when he comes out of this, and then the day after that.” Ryu had thrown 4 2/3 innings and 89 pitches, few of which fooled the opposition.Roberts called it “a victory in itself,” and Ellis also preferred the long view.“We’re excited to see what he did today, but also the rest of the year,” Ellis said. “He came out firing, and it was great to see. He had a good heater and showed it from the get-go. Regardless of the outcome, it was so much fun to see him out there. The fastball and changeup were very similar to what he was, or what it is.”“But to expect him to come out and do what McCarthy did, that’s a high expectation,” Roberts warned.It was, but the Dodgers brought it on themselves, using Ryu the night after their nine-pitcher, 14-inning nightmare against Baltimore Wednesday. Roberts confronted this game with only three position players on his bench.Put it this way: This was not July 31, come early. The Dodgers were hoping Ryu’s return would be like a bountiful trade in which they gave up nothing. Instead, Ryu became the ninth Dodger pitcher to start a game in a 14-day span.Ryu’s exile has been an underrated problem for L.A. He had given the Dodgers two solid years, with 41 quality starts in 56 games and a 17-8 road record. In that last game, Ryu left Game 3 in St. Louis tied after six innings, 1-1, before Dodger bullpen follies took over.“He proved he was a big-game pitcher, a No. 2 or No. 3 starter,” Ellis said. “We’ve missed him. But suddenly we have a lot of guys coming back to our rotation who are savvy guys. They can add quality depth.”Not to plow up old ground, but the Dodgers knew for at least a year that Zack Greinke’s departure was a possibility. They did not land Cole Hamels, with his ridiculously favorable contract and his devastating changeup, from Philadelphia and they let Johnny Cueto take a direct free-agent flight to San Francisco, where he might well win the Cy Young Award.The real July 31 trade deadline still looms. But any Dodgers improvement will require something more than free. LOS ANGELES >> A.J. Ellis said the mere sight of Hyun-jin Ryu was a pick-me-up bouquet for all the Dodgers Thursday night.Sullen fans at Dodger Stadium were more concerned with the sound.Ryu’s first game since the 2014 Divisional Playoff might have been an inspiration, but it was also a 6-0 loss to San Diego,It was diffcult to anticipate that the left-hander would be wild-card ready. He was coming off labrum surgery … but Dodgers fans had swallowed a dose of hope on Sunday when Brandon McCarthy had thrown six two-hit innings in his first post-rehab start. Newsroom GuidelinesNews TipsContact UsReport an Error If Ryu could pitch just as strongly and if Clayton Kershaw could overcome his back problems and if Brett Anderson could return and if Kenta Maeda and Scott Kazmir could keep hanging on, maybe the Dodgers could patch together a rotation that could hold off the Mets, Cardinals, Mattinglys and Pirates …Warning: Never trust a paragraph with so many “ifs” and “coulds.”Ryu’s first pitch to Melvin Upton Jr. was an 89-mph ball. His sixth pitch was 92 mph coming in and 102 mph going out, a home run into the right-center pavilion, and a 1-0 lead for San Diego.The second inning was slower and more painful for Ryu. He walked catcher Derek Norris because he couldn’t place his fastball, and he gave up a base hit to Alexi Ramirez. With two outs he allowed pitcher Drew Pomeranz to send a grass-riding single through the middle.The fourth inning featured a 3-0 count to Norris and an eventual base hit, and Norris went to second on Corey Seager’s imprecise throw. Then Ramirez whaled a double off a 91-mph fastball, and the Padres led 3-0 after four innings.
