BALTIMORE -- The Orioles will try to back off right-hander Jason Berken for the next day or two to give the struggling reliever -- who has thrown an American League-leading 60 1/3 innings -- a much-needed break.

Manager Buck Showalter said the hope is that resting Berken will "freshen him up a little bit," and he has talked with pitching coach Rick Kranitz about monitoring Berken's second-half innings.

A former starter who made his first Opening Day roster as the team's long man, Berken's emergence has been one of this season's biggest surprises. But after allowing just eight earned runs over 45 innings in his first 27 games, Berken's effectiveness has waned, giving way to 13 runs in his last 16 2/3 innings.

Berken, who was conferring with Kranitz on Sunday morning, said he's rushing his delivery a little bit and the deception on his pitches isn't as sharp as earlier in the year. Given that it's a minor adjustment, Berken said he's not in panic mode and just needs to go after opposing batters a little more aggressively, to stay out of favorable hitting counts. He's walked five batters in his last eight outings, after issuing just 14 free passes in his previous 32. Following Friday's two-out walk to Alexei Ramirez, who scored on the following double, Berken called his lack of location "not acceptable" and was more upset about the free pass than the hits.

Reliever Patton optioned; Tatum recalled

BALTIMORE -- Following Sunday's season-high fifth consecutive quality start, the Orioles finally felt comfortable enough to bolster a thin bench, optioning reliever Troy Patton to Triple-A Norfolk on Sunday.

The move cleared a roster spot for a position player. Catcher Craig Tatum was recalled from Triple-A Norfolk on Monday.

Patton had been in uniform for eight games, but hadn't seen any game action and was optioned over Armando Gabino presumably so that the lefty could get some consistent innings.

"It's really a tough situation," Patton said. "I came up here to be a long relief guy and it just happens to be the one week of the season that literally no long relief guy was needed.

"I understand it. It's good that I go back down there [to Norfolk] and throw a little bit so that if I'm needed in September, I can be fresh."

In two stints with the Tides earlier this year, Patton went 7-9 with a 4.80 ERA in 20 starts and joined the Orioles for the Aug. 1 finale in Kansas City. With a struggling rotation, the thought was Patton would provide long relief. But given the O's surge in their starting rotation -- which has pitched to a 1.94 ERA in the first six games of their homestand -- his role became unnecessary.

The O's bench, which consists mainly of Julio Lugo, Jake Fox and Corey Patterson will be bolstered by a fourth addition to provide new manager Buck Showalter with more options for in-game substitutions and pinch-hitters.

Markakis charity event Sunday
