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."
