SAN DIEGO -- Chris Davis struck out in each of his first two at-bats Wednesday. He flied out with the bases loaded in the fifth.
He certainly made the most of his next opportunity.
"The thing about Chris," manager Buck Showalter said, "he is so lethal that he may have some bad at-bats, but you never think he's not a swing away from really doing something good for you."
Davis belted a tiebreaking three-run shot into the bleachers in right-center on the first pitch from Colt Hynes. The drive traveled an estimated 453 feet, making it one of the longest home runs in the history of spacious Petco Park.
"I don't know if it's the longest one I ever hit," Davis said, "but it's one of the longer ones. It helped that the wind was blowing out a little bit.
"I think I had some pitches earlier in the game that I could have hit, so to get that pitch early and to put a good swing on felt pretty good."
"I have felt good the last couple of games," said Davis, who went 2 for 4 in Tuesday's 4-1 victory. "I feel comfortable in the box, but haven't had much to show for it."
San Diego wasted a solid start by Eric Stults, who allowed three runs, two earned, and five hits in seven innings. He struck out six and walked one.
Hardy hit his 19th homer in the second, and the Orioles used San Diego's sloppy defense to score single runs in the fourth and fifth.
Machado reached on second baseman Gyorko's error in the fourth. Adam Jones followed with a sharp single up the middle and Machado came around to score when Amarista threw the ball into Baltimore's dugout while trying to get the runner at third.
Stults' error on pitcher Miguel Gonzalez's sacrifice in the fifth allowed the Orioles to load the bases with no outs. Nick Markakis popped out, but Machado single to center to give Baltimore a 3-0 lead.
Gonzalez struck out eight in six innings and was charged with three runs and six hits.
"I felt Miggy was as good as anything that happened in the game," Showalter said. "He gave a up a 3-2 walk and a broken-bat single to left and then made one or two mistakes. The game isn't always fair."
Hardy tacked on a two-run single in the ninth and finished with three RBI.
- Padres OF Carlos Quentin (right knee) remained out of the starting lineup. He could be headed for the disabled list if he is unable to play this weekend in Cincinnati. "We are giving him every opportunity to get to the point where he can play whether it's in a pinch-hitter role or back on the field full bore," manager Bud Black said. "We are coming closer to the decision whether to put him on DL or whether we can wait another day or two."
- SS Ronny Cedeno, who was promoted on Tuesday, went 0 for 4 in his San Diego debut.
- Orioles RHP Jason Hammel, who is on the DL with a right flexor mass strain (between forearm and elbow), tried to throw Tuesday, but manager Buck Showalter said he's still experiencing "some discomfort" and might not be ready to come off the DL when he's eligible on Tuesday.
- Showalter said minor-league LHP Tsuyoshi Wada from Japan could be a potential September call-up as a reliever and possibly a starter. He threw five scoreless innings for Triple-A Norfolk on Tuesday night and has had back-to-back scoreless outings.
