SAN DIEGO -- The Orioles' dugout had a good laugh during Wednesday's 10-3 win when reliever Darren O'Day got his first career at-bat, a ninth-inning strikeout facing Padres reliever Sean O'Sullivan.
"Quite a bit," O'Day said when asked how much ribbing he got from teammates as he walked back after the four-pitch at-bat. "Everybody had a good laugh, which they should. It was a good moment. I got to hit once, this is my sixth year [in the Majors], I got to wait six more years to hit again.
"I haven't had to calm myself down on the mound that much in a while. The adrenaline of hitting is different, a lot of fun."
O'Day, who recorded the final out of the eighth inning, was told by manager Buck Showalter that he'd take his turn to hit and go back out for the ninth.
"We couldn't lose there," said Showalter of the decision. "If Darren got a hit, we'd have something to talk about. If he struck out, we've got something to talk about. "
O'Day, one of the more outgoing personalities in the Baltimore clubhouse, joked to reporters that he was a big "opposite-field guy" after admitting he had no batting helmet, gloves or bat.
"I was walking up there thinking, 'Is this really happening? Am I really getting to hit?'" said O'Day, who last stepped into the batter's box in a summer league in 2002. "Because we joke around about what we would do if we got to hit. It was a lot of fun. Very disappointing with the strikeout. Because before I went up there, I envisioned myself rounding first, easing to second with a nice double. But it didn't happen that way."
Hammel has setback in throwing session
SAN DIEGO -- Jason Hammel, who has been sidelined with a right arm injury, experienced a setback while throwing on Tuesday.
"It was a slight improvement, but it was disappointing that it didn't heal after a week of not throwing," said Hammel, who will try to throw again on Friday. "I can't predict the future, but as of right now, it doesn't look too good" to come off the disabled list when he is eligible.
The right-hander was placed on the disabled on July 31 (retroactive to July 29).
"Still had a little discomfort, so we are not there yet where he's in throw mode," manager Buck Showalter said. "[Aug. 13] is his eligibility [date], today is the 7th. If you go through the throwing and what have you, he will probably pitch in a [rehab] game, maybe. I don't think that's moving at a real fast clip. We were hoping yesterday he would throw and want to go to the next step.
"It's not bad, but it's not completely gone. Some of it is still lingering. Makes me a feel a little better about DL'ing him in the first place, because I was kind of iffy."
The 30-year-old Hammel is 7-8 with a 5.20 ERA in 21 starts and has been dealing with what is being called right flexor mass tightness since Spring Training, with the team opting to place him on the DL when they acquired starter Bud Norris at the Trade Deadline.
Showalter said part of Hammel's rehab is taking medication to reduce the inflammation, and he could start feeling better over the next couple days.
O's turning Petco Park into Camden Yards West
SAN DIEGO -- Camden Yards, West?
The Orioles, like a lot of teams, have some strong California ties, but the reception in Tuesday's series opener in San Diego was still a surprise. A significant portion of the announced crowd of 28,055 at Petco Park was pulling for Baltimore -- at one point circulating a "Let's go O's" chant -- and it didn't go unappreciated in the visiting clubhouse.
"The coolest part about it was the 'O' during the national anthem," said San Diego native Adam Jones, who got some of the loudest cheers of the night. "There were a lot of guys down the third-base line that screamed right in our ear. And I think it shocked us a little bit, and I think got us going a little bit. That's cool. I know my Twitter is blowing up, a lot of people have flown out here and made the trip."
"That was impressive, how many O's fans," Nate McLouth said following the team's 4-1 win. "I didn't know 2,500 miles away there were that many O's fans out here. I don't blame them for coming out here for this weather."
The Orioles are playing in San Diego for the first time since 2010, and the friendly atmosphere in opponent territory was appreciated by new starter Bud Norris, who picked up his second win in as many tries in a Baltimore uniform.
"It's great when you can get the support like that, a fan base all across the land," said Norris, who was traded from Houston at the Trade Deadline. "It's special, Birdland and all. ... You're trying to lock them out as best as you can, try to play the game, but any time you hear them and get a little boost, it's pretty special."
