BALTIMORE -- Buck Showalter has a catchphrase he likes to use when speaking about his club: "I like our guys."

The manager's mantra is so popular that the Baltimore Orioles even gave away T-shirts this season with Showalter's words of wisdom emblazoned across the front.

That philosophy also played into the Orioles' reluctance to make a big splash when the non-waiver trade deadline passed Thursday afternoon. Baltimore did acquire left-handed reliever Andrew Miller from the Red Sox, but the club shied away from making a push for some of the big-name starters, namely Tampa Bay Rays left-hander David Price and Boston left-hander Jon Lester and right-hander John Lackey.

Still, a minor move to improve the bullpen could make a significant difference for Baltimore.

"We need to get to the postseason, and we need to stay on pace to win over 90 games," Orioles vice president Dan Duquette said. "But to get beyond winning the division and advancing in the postseason, we do need to strengthen our team, and this is one area where we could strengthen our club without giving up an asset on the current team."

The Orioles' bid for an American League East crown was helped by other teams in the division when Boston traded Lester to Oakland and Lackey to St. Louis. Price was shipped to Detroit, making the Tigers an even bigger threat to make the World Series.

The Orioles made it clear they would not trade any of the three top young pitchers in the organization -- Kevin Gausman, Dylan Bundy and Hunter Harvey. The Orioles were rumored to be close to trading for Lester earlier in the week, but Duquette dismissed those reports.

"Some of the long-terms prospects for our pitching we think are very valuable to the long-term sustainability of the organization," Duquette said.

Nonetheless, he did not rule out making another move in August, namely adding an extra bat.

"We still have a good chance to win each game because of the power we have in the lineup," Duquette said. "There are a couple areas in the ballclub where we could use some additional offensive production, and there will be some opportunities I think to address that between now and the end of the season."
