LOS ANGELES — Hyun-Jin Ryu struggled in the first inning against the Boston Red Sox. Eventually, the rookie settled down but his team mounted its comeback too late.
Ryu lost consecutive decisions for the first time in his career, giving up four runs and five hits in the Los Angeles Dodgers' 4-2 loss on Sunday that ended their four-game winning streak.
Jonny Gomes hit a three-run homer off Ryu in the first inning, when Boston scored all of its runs.
"He's trying to get comfortable out there. Even Clayton (Kershaw) has had problems out there in the first inning," catcher A.J. Ellis said. "You want to get comfortable and get some quick outs."
Pitching under a searing sun in 82-degree heat, Ryu (12-5) hit Shane Victorino with a pitch before Dustin Pedroia reached on an infield single to second with one out. Victorino scored on Mike Napoli's RBI single.
Gomes followed with his 11th homer on Ryu's next pitch, scoring Pedroia and Napoli to make it 4-0. Ryu struck out Stephen Drew and Will Middlebrooks to end the inning.
"I don't think it's the issue of warming up," Ryu said through a translator. "It seems as the game goes on my body seems to relax more."
Ryu posted zeroes the rest of the way, but his five innings tied his shortest outing of the season. The left-hander struck out seven and walked none in losing his second straight start after winning six in a row. He caught a cold returning from the trip to Miami, but said it didn't affect his pitching.
"The lesson is don't give up too many runs," Ryu said.
The Dodgers mounted a comeback with two outs in the eighth. They trailed 4-2 on Adrian Gonzalez's RBI double off Craig Breslow. After Breslow walked Hanley Ramirez to put the tying runs at first and second, Uehara ended the inning by striking out Ellis.
"It was kind of a tough situation giving up four, pretty discouraged by it," Ellis said about Ryu. "But he gave us a chance to get back in the game."
The Red Sox won at Dodger Stadium for the first time in five games dating to their first visit in 2002, when they were swept in three games.
Jon Lester (12-7) gave up one run in 7 1-3 innings, struck out six and walked four.
Koji Uehara got the final four outs to earn his 13th save in 16 chances.
Lester retired eight of the first 10 batters he faced before the Dodgers notched their first hit, a single by Mark Ellis in the fourth.
The Red Sox backed Lester with two double plays, including Drew's one-man double play that ended the seventh. He caught a soft line drive off the bat of Juan Uribe and then sprinted to second to double off Ramirez.
Hours after Ricky Nolasco limited the Red Sox to two hits in a 2-0 on Friday, Ryu fell to 6-2 at home.
Dodgers' starters hadn't allowed a run in their previous 26 innings dating to Wednesday, their second-longest scoreless run of the season.
