“My split was fine today,” Haren said. “I made one mistake with it and Amarista hit it out. I’m not getting away with much.”Since it’s July, and since the Dodgers’ shortcomings weren’t isolated to one night, they will be viewed through the prism of the trade deadline. Players can be traded without having to pass through waivers for another 20 days.Haren’s recent struggles, and Josh Beckett’s left hip injury, raise the probability that the Dodgers will attempt to acquire a starting pitcher. Mattingly downplayed any cause for concern over the two pitchers, as is his habit.“I have confidence in Danny,” Mattingly said. “Josh is doing well. I’m not too worried.”The team-wide struggles to defend center field can’t be ignored either.Van Slyke, Matt Kemp and Andre Ethier are all below zero in terms of Ultimate Zone Rating and FanGraphs’ version of defensive Wins Above Replacement (dWAR). These are the only outfielders who have played center field for the Dodgers this season.For those in the prospect cult clamoring for 22-year-old Joc Pederson to be promoted from Triple-A, there is a tantalizing center fielder already in the organization. But Pederson’s defense is unproven at the major-league level. The Dodgers might look to deal Pederson and/or another outfielder for a more proven defender, or a pitcher.Haren, historically a better pitcher after the All-Star break, might be on the trading block himself. By pitching another 67 1/3 innings this season, his $10 million option for next season kicks in. If he’s traded, the option increases to $11 million, and that might make him more valuable to the Dodgers than another team.If the status quo continues, the Dodgers might survive into October anyway. The loss, their third in four games, dropped their record to 52-43. Because of the San Francisco Giants’ 5-0 win over the Arizona Diamondbacks, the Dodgers are in a virtual tie with the Giants (51-42) for first place in the National League West.A line-drive single by Kemp in the bottom of the first inning scored Yasiel Puig with the game’s first run. The Dodgers never led again. Amarista’s home run in the second inning put the Padres ahead, 2-1. It was the 19th home run Haren has allowed this season, tied for second in the National League.The Dodgers had a couple chances to at least tie the Padres late. With Dee Gordon on third base and Puig on second, Adrian Gonzalez lofted a fly ball to left field, deep enough to score Gordon with the Dodgers’ third run.Puig tagged up and unwisely tried to take third base on Gonzalez’s fly ball. Headley cut off Quentin’s throw from left field and easily tagged out Puig, completing a rare 7-5 double play that ended the seventh inning.With two outs in the eighth inning, the Dodgers loaded the bases against Joaquin Benoit. But Carl Crawford grounded out on a 97-mph fastball to end the inning.Huston Street pitched a perfect ninth inning for his 24th save.Crawford’s pinch-hit appearance in the fifth inning was his first plate appearance since going on the disabled list May 20. Hanley Ramirez, scratched from the starting lineup because of shoulder inflammation, served as a decoy in the on-deck circle in the seventh inning. He didn’t bat when Puig ran into the inning-ending double play. Newsroom GuidelinesNews TipsContact UsReport an Error Even when Dan Haren managed to contain a long fly ball to the warning track Friday, it didn’t land in an outfielder’s glove.That’s not quite accurate. In the fifth inning Scott Van Slyke turned and ran for the fences, reached up at the last second with his back to home plate, stuck out his left arm and momentarily gloved a 390-foot Chase Headley smash. As soon as the miraculous catch appeared, it was gone in a flash like a flailing, bearded supernova.The ball bounced in and out of Van Slyke’s glove for a double. The San Diego Padres scored again and soon, Haren was finished. So were the Dodgers.San Diego won, 6-3, beating the Dodgers for the third time in eight meetings this season. Haren (8-6) allowed four runs in four innings. He didn’t retire any of the three batters he faced in the fifth: Seth Smith singled, Headley doubled off Van Slyke’s glove to score Smith, and Carlos Quentin doubled to score Headley.“I’ve felt good the last few times out and most of them have not been very good,” Haren said. “I don’t know. I’m searching right now. I went through a similar thing last year. The All-Star break came and I was able to kind of turn the page and string together some good ones. “I’m going to step back for a day or two. It’s been an up and down first half.”Haren’s earned-run average, 3.57 at the end of June, has ballooned to 4.23 over his last two starts.He showed no sign of reversing the trend early. He walked a batter in the first inning and allowed a home run to lilliputian shortstop Alexi Amarista in the second.
