The Dodgers got beat 3-2 by Arizona on Wednesday night for their season-high seventh straight loss. The Diamondbacks swept the series, with Paul Goldschmidt homering four times in three games.
"It seems like every night we're finding different ways to lose. That's the hard part about it," said Kershaw, who has three no-decisions in his past four starts.
"You go through ups and downs throughout the course of the year, but I didn't expect us to be 13-20 now," he added. "It's not a good feeling to have this type of losing streak, regardless of the type of talent we have in this room."
Kershaw allowed two runs—one earned—and five hits in seven innings. The left-hander struck out four and walked one in his 20th straight start allowing three or fewer earned runs, the longest such streak for a Dodger since Orel Hershiser's 20-game run in 1989-90.
"Every time he steps on the mound, it should be a win. He's the premier pitcher in all of baseball, and we're letting those games get away that should be wins," catcher A.J. Ellis said. "With the way this team's put together, we feel like we should win when all of our guys are on the mound.
Goldschmidt hit a two-run homer off Kershaw in the sixth inning that tied the game, and then he homered to left field in the eighth with two outs off Kenley Jansen (1-1).
"It seems like Goldschmidt's been a one-man wrecking crew on us," Dodgers manager Don Mattingly said. "It doesn't really matter who's been out there. He's hit three of our best guys."
Matt Kemp and Andre Ethier were a combined 2 for 8 with three strikeouts for the Dodgers, who have yet to win this month.
"When we pitch good, we don't hit. When we hit, we don't pitch good," Kemp said. "It's not the manager's fault. He doesn't go up there and swing the bat for us, pitch for us, steal bases, or do the base running."
First baseman Adrian Gonzalez extended his hitting streak to seven games before coming out of the game in the fifth after aggravating his strained neck when he dived for a pop foul by Will Nieves. He's day to day.
"He didn't look real good when he came out," Mattingly said. "It seems like he aggravated that neck pretty good."
Already on the DL are shortstop Hanley Ramirez, infielders Mark Ellis and Jerry Hairston Jr., and pitchers Zack Greinke, Chad Billingsley, Scott Elbert, Ted Lilly and Stephen Fife.
"Everybody knows what we need to do, and that's score runs and get those big hits. But we're not doing it right now," Kemp said. "We all need to get on the same page and get this thing going."
Wade Miley (3-1) outlasted Kershaw in a matchup of two of the best left-handed starters in the NL over the past two seasons.
Miley allowed two runs and seven hits in 7 2-3 innings, struck out four and walked none.
Heath Bell pitched the ninth to earn his third save in four chances.
He was called upon after closer J.J. Putz went on the 15-day DL earlier in the day with a strained right elbow that he hurt in the ninth on Tuesday.
Jansen gave up one run and one hit in one inning. He struck out two and walked none in the loss.
Arizona tied the game at 2 on Goldschmidt's first homer in the sixth. Didi Gregorius reached on a throwing error by shortstop Dee Gordon to open the inning and Goldschmidt followed with his second two-run shot of the series. His other one snapped a tie in the ninth on Tuesday and gave the D-backs a 5-3 victory.
The Dodgers led 2-0 on RBI doubles by Nick Punto and Gonzalez that both found the right field corner in the fourth.
NOTES: The D-backs recalled RHP Will Harris from Triple-A Reno to fill Putz's roster spot. ... It was the third series this season and second straight in which the Dodgers have been swept. ... Kershaw is one out shy of reaching 1,000 innings in his career, which would make him the 38th pitcher to toss that many for the Dodgers since 1900. ... Gonzalez turned 31 on Wednesday.
