The moment I took notice was when reliever Darren O'Day escaped a bases-loaded jam in the seventh by striking out Cody Ross swinging and Ryan Lavarnway looking, prompting a loud standing ovation going into the seventh-inning stretch.
When manager Buck Showalter took over just more than two years ago, he said he wanted to build a winner in Baltimore so successful that Red Sox and Yankees fans couldn't get a seat at Camden Yards.
They could Tuesday, but it was definitely a different atmosphere.
"Better than it was two years ago," Showalter said. "There's a little bit more to be proud of, too. They still will be able to get tickets, I'm sure. It would be nice if we could get to that point where they're listening to it on the radio outside."
And yes, the Red Sox are now floundering three games under .500 and the Orioles are 10 games over .500 and in one of the two AL wild-card spots. And there still was a share of Red Sox fans Tuesday night – they made their presence known by booing Josh Beckett off the field in the sixth.
