BALTIMORE (AP) — The Baltimore Orioles can’t put a winning streak together, a shortcoming that can be attributed primarily to one glaring weakness: poor starting pitching.Ubaldo Jimenez gave up three home runs, two by Ryon Healy, and the Orioles lost to the Oakland Athletics 6-4 on Tuesday night to fall another notch in the wild-card chase.The Athletics used homers by Jed Lowrie and Healy to take a 3-0 lead in the first inning, and Healy connected in the fifth for a five-run cushion.Manny Machado hit a two-run homer in the sixth for Baltimore and Jonathan Schoop singled in two runs in the eighth to make it 5-4, but Khris Davis blunted the comeback with his 34th home run in the ninth.The Orioles haven’t won consecutive games since Aug. 5-7. The loss dropped them behind Tampa Bay and they now trail six teams for the second AL wild card.Baltimore needs to make something happen — quickly.“We’re going to have to be consistent in our starting pitching to have that type of momentum,” manager Buck Showalter said.This loss was similar to many that preceded it.“We created a real hole for ourselves,” Showalter said. “Sometimes we climb out of it, sometimes we don’t.”Jimenez (5-9) has won only one of his last eight starts.
