Last night, left-hander Wade Miley provided the Orioles with what has lately been a rare quality start. But they could not get two in a row tonight.

Right-hander Ubaldo Jiménez allowed five runs and three homers over five innings as the Oakland Athletics beat the Orioles 6-4 at Oriole Park.

A late-game O's rally fell short. They pulled within 5-4 on Jonathan Schoop's two-run single in the last of the eighth. But a solo homer in the ninth by the A's Khris Davis off Darren O'Day accounted for the final margin.

Jiménez allowed two homers as he and the Orioles fell behind 3-0 in the first inning. When Ryon Healy drilled a two-run shot in the fifth for his second home run of the game, Oakland opened a 5-0 lead.

The Orioles fall to 2-3 on this homestand and to 61-65 for the year. They have lost five of seven and nine of the last 14 games. They are 37-26 at home.

Manny Machado got the Orioles on the board with a long two-run homer to the right of center field in the last of the fifth to make it 5-2. He crushed No. 27 a distance of 456 feet on an exit velocity of 110 mph off right-hander Simon Castro. It was Machado's fourth-longest homer of the year.

Over his past 10 games, he has six homers and 17 RBIs. Over his last 16 games, he is batting .343 (24-for-70) with eight homers and 27 RBIs.

But Jiménez allowed a two-run homer in the first to Jed Lowrie and a solo homer to Healy as the Orioles fell behind in the opening inning. Over five innings he allowed nine hits and five runs and Jiménez falls to 5-9 with an ERA of 6.57. Over his past three starts, he has allowed 14 runs in 14 2/3. In eight starts since the All-Star game, Jiménez is 1-5 with a 6.38 ERA.

O's pitchers have just two quality starts the last nine games and have thrown 5 1/3 or fewer innings in six of the last seven games.

Oakland starter Paul Blackburn was literally knocked from the game. He took a Trey Mancini liner off his right arm to start the home fifth and was taken out of the game as Castro came on. He pitched four scoreless on three hits and got 10 of his 12 outs on grounders.

The Orioles were down by five in the sixth but closed to within a run as Schoop drove in his 92nd and 93rd runs of the year. But they wind up losing by two as the A's win at Camden Yards for just the second time in their last nine games.

This series is now even at a win each and the third and deciding game is set for Wednesday afternoon. Right-hander Dylan Bundy (12-8, 4.17 ERA) gets the start for the Orioles and lefty Sean Manaea (8-8, 4.58 ERA) goes for Oakland.
