CLEVELAND — - In the first two weeks of September, the Orioles promoted six relievers and acquired another, left-hander Sean Henn, in a minor league trade.

The hope was that the additions would bolster a tired bullpen and give several pitchers an opportunity to show that they belong at the major league level. What it has done instead is reveal a lack of organizational depth in that area and likely made several necessary offseason roster decisions much easier to make.

In the first 21 games this month, the Orioles bullpen has a 6.43 ERA, having allowed 50 earned runs in 70 innings.

"Opportunity doesn't last forever," Orioles manager Dave Trembley said. "These games in September are just as important as they are in June, July and August. Opportunities are provided, but it's up to the individual to take advantage of the opportunity and leave a positive impression on those people that make decisions."

Few Orioles have done that in a bullpen in which eight of 12 members have ERAs over 5.00 this month, including four with ERAs over 10.00. Henn, who was acquired from the Minnesota Twins, has made five scoreless appearances, though he did allow an inherited runner to score in his most recent appearance. Alberto Castillo, another left-handed specialist, has been Trembley's most reliable relief option this month as the 34-year-old has a 2.25 ERA in 13 appearances since rejoining the club.

But the other additions have mostly faltered. Right-hander Bob McCrory, once considered one of the organization's most promising young relievers, has allowed nine earned runs, 11 hits and five walks in four outings this month spanning just 2 2/3 innings. Chris Lambert has a 6.75 ERA this month, while Chris Waters' stands at 10.13 and Dennis Sarfate's at 6.75.

Those four, along with right-handers Matt Albers and Brian Bass, are candidates to be taken off the 40-man roster in the offseason.

"It's kind of spread," said Trembley, who has also watched his two best relievers, right-handers Jim Johnson and Danys Baez, struggle this month. "You have to keep the ball in the ballpark. You can't give free passes by hitting people and walking people. You have to be able to field your position, hold runners. If you can't do that, you're not a major league pitcher. It's that simple. The opportunity is provided, but if you show on a repetitive basis that you can't do those things, you eliminate yourself."

Tillman's swan song
Though the Orioles aren't saying it officially, today's start will likely be the last for prized rookie right-hander Chris Tillman. In 29 combined outings between the majors and minors this season, the 21-year-old has logged 159 2/3 innings after throwing 135 2/3 last year.

The Orioles, who have already shut down rookie left-hander Brian Matusz, don't want Tillman to have much more than a 20 percent increase in innings over last year. A 20 percent increase would mean approximately 162 innings, a mark that Tillman would pass if he gets through the third inning today.

Waters is the likely candidate to take Tillman's final turn in the rotation.

Pie's status
The Orioles got relatively good news about injured outfielder Felix Pie, who will likely miss a couple of games and does not appear done for the season.

Pie suffered a left quadriceps strain trying to beat out a double play in the seventh inning Friday night. After passing first base, he collapsed to the ground and threw his helmet in frustration.

"Richie Bancells, our head athletic trainer, thought it was going to be a whole lot more severe than what it is," Trembley said. "Thank God, it's not. The kid has played very well for us. We're confident that we'll be able to get him back. He did get checked out last night here by the Indians' team doctor, and he will be checked out again Monday when we get to Tampa."

Pie, who has filled in admirably in center field in Adam Jones' absence, won't play again in this series but should return for the final week. With Pie out, Lou Montanez made his first start in center field.

Around the horn
The Orioles and Washington Nationals, who entered Saturday night with 194 combined losses, are poised to become the first pair of teams in a shared market to post 200 combined defeats since the Philadelphia Phillies (108 losses) and the then-Philadelphia Athletics (98) did it in 1945. ... Shortstop Cesar Izturis is dealing with a virus and was held out of the lineup. ... Second baseman Brian Roberts is two walks shy of recording his third season with at least 25 steals, 50 doubles, 70 walks and 100 runs scored, a feat that has been accomplished by only four other players since 1900. Tris Speaker, Kiki Cuyler, Craig Biggio and Bobby Abreu all did it once.
