With nearly two dozen Orioles greats in attendance to commemorate the franchise's 60th anniversary, manager Buck Showalter felt a certain pressure for his club to perform Friday night against the St. Louis Cardinals.

As the Orioles wore cream-colored replicas of the inaugural 1954 club's uniforms, the organization welcomed back 23 Orioles Hall of Famers with an elaborate postgame ceremony, complete with a fireworks display and laser-light show.

But the fireworks started early. The current Orioles were a fitting opening act, hitting a season-high six homers in their most dominating performance of the season, a 12-2 win over the defending National League champion before an announced near-sellout Camden Yards crowd of 43,743.

As they walked back into the home clubhouse after their most lopsided victory of the year, Orioles players were welcomed by Orioles of the past.

“I still got chills. We just came out of the runway, and all of the [Orioles] Hall of Famers are greeting our guys as they come off the field,” Showalter said. “That's pretty cool. ... I think if you take pictures [tonight], those are keepers.”

This year's club, which leads the American League East by five games over the New York Yankees, is attempting to make its own history. Since July 1, the Orioles are 23-10, and with Friday's win, the Orioles (66-49) are a season-high 17 games over .500.

“This last month has been crazy for us,” said third baseman Manny Machado, who hit the first homer of the night, a three-run blast over the Orioles bullpen in left-center. “It's been hard. It's been a grind. It's really putting us in a position where we know we can play baseball. It's always good to have one of those games like that, when everything's falling, base hits are falling. We're hitting the ball out of the park.”

After averaging just 2.5 runs over their past 11 home games, the Orioles set a season high at Camden Yards and scored their most since a 14-5 win at the New York Yankees on April 8, their eighth game of the season.
