BALTIMORE -- The Orioles and Rays, along with the rest of Major League Baseball, held a moment of silence before Tuesday night's game in remembrance of the events of Sept. 11, 2001, and to honor the country's service members.

Members of the U.S. Army chorus sang the national anthem, and the Orioles wore special caps with an American flag above the left ear flap for the game.

"When I was writing out the lineup today to give to [bench coach John Russell], when I wrote 9-11, I stopped for a second," manager Buck Showalter said. "It was a reminder."

Showalter was not managing at the time, but he has ties to New York City as the former Yankees manager, and he also served as a baseball analyst for ESPN -- based in Bristol, Conn. -- in two separate stints.

"I think the normalcy, playing that game [after Sept. 11], I don't want to get too deep here about that whole game, but you play as much a role as someone who is smarter than you deems you should play in it," Showalter said of baseball's decision to resume play following the attacks.

"It makes you realize ... what we do each day is not that important. It is for those three hours, and believe me, we grind the heck out of it, but when you see that scale, it's like, really? I'm worried about that? I got my own feeling on it. ... It's why we are able to do what we do."

Tillman's first session since injury goes well

BALTIMORE -- Orioles pitcher Chris Tillman threw a bullpen session Tuesday afternoon -- his first since being diagnosed with right elbow inflammation -- and he said everything felt great.

"We will see how Tillman feels tomorrow. I want to make sure he recovers well before we see where that might plug in," manager Buck Showalter said of the team's rotation, which is uncertain beyond Miguel Gonzalez on Wednesday. "We got three or four guys we are considering for Thursday, we will see how it shakes out the next day or two."

Tillman exited his start on Sept. 2 in New York after three innings with what he described as "dead arm," and the 24-year-old's MRI showed some inflammation but an otherwise healthy ligament.

Getting Tillman back into the rotation will help add some stability to an O's rotation that has been pieced together for most of the season, but bolstered by Jason Hammel's return. However, Hammel left his start on Tuesday after 3 2/3 innings because of a right knee injury.

In 11 starts for the Orioles this season, Tillman is 7-2 with a 3.39 ERA.

Tidbits

• Troy Patton (right ankle sprain) will throw a side session Wednesday in Sarasota, Fla. Assuming all goes well, the lefty will throw live batting practice on Friday.

• Showalter had Triple-A manager Ron Johnson and pitching coach Mike Griffin join him in Tuesday's pregame media session with reporters, as he wanted to publicly thank both of them for all their hard work this year. With the Orioles' revolving door of roster moves, Norfolk used 75 different players in 2012 -- Johnson's first in the organization.

• Jim Thome (herniated disk in his neck) is expected to take batting practice in the cages of the team's complex in Sarasota on Wednesday.
