SEATTLE -- Injured Mariners closer David Aardsma threw 27 pitches in a simulated inning of work Tuesday as he continued his recovery from hip labrum surgery.

Manager Eric Wedge said Aardsma threw well and will now work two simulated innings of about 15 pitches each on Friday in Kansas City. If all goes well there, he'll likely be sent out on a rehab assignment in the Minor Leagues before returning to the Mariners.

Wedge didn't set a timeline, but he noted that as a late-inning reliever, Aardsma won't need as much time to get ready as would a starter or long man.

Aardsma pitched to Franklin Gutierrez, Ryan Langerhans and Chris Gimenez on Tuesday and didn't give up any solid contact. Gutierrez lifted one fly ball to right field and Gimenez hit a soft grounder to shortstop.

Wedge said that when Aardsma is ready, he'll return as the closer.

"That's his mentality. That's what he is," Wedge said. "As long as he's comfortable with it, we are."

Moore likely out for season with tear in knee

SEATTLE -- Mariners catcher Adam Moore underwent surgery on his right knee on Tuesday, and the news wasn't good.

Moore suffered an "extensive tear" of his medial meniscus and faces a 4-6 month rehabilitation, according to Mariners team physician Edward Khalfayan, and he will likely miss the remainder of the season.

Moore hurt his knee Wednesday in the eighth inning of the Mariners' final game at Texas when his foot slipped as he chased after a ball that got away from him behind the plate.

Moore was working as the backup to Miguel Olivo this season and had played in two games, going 1-for-6 with a double. The 26-year-old has played 68 games for the Mariners in parts of the past three seasons.

He missed considerable time last year with an injury to his other knee, suffering a sublexed fibula before returning to Triple-A Tacoma and eventually finishing out the season in Seattle.

Chris Gimenez has replaced Moore as the backup catcher.

Lueke relishes first victory in Mariners' 'pen

SEATTLE -- A bullpen that started the season with considerable question marks has been a strength for the Mariners in recent days, with all seven relievers contributing to 15 consecutive innings of scoreless work during the first four games of the homestand.

Rookie Josh Lueke has made three one-inning appearances in that stretch and notched his first Major League victory Monday with a 1-2-3 ninth in Seattle's 8-7 comeback win over Toronto.

"It was nice to see that rally," Lueke said. "It was something special, for sure."

Aaron Laffey and David Pauley also have thrown three shutout innings in the past four games, with Chris Ray and Jamey Wright contributing two innings each and rookie Tom Wilhelmsen and closer Brandon League hurling a scoreless frame apiece.

"We won that game because of the bullpen," Felix Hernandez said Monday after leaving with a 7-0 deficit. "They held down some good hitters. They've been pretty good."

Luis Rodriguez had the winning hit, but he insisted Lueke keep the game ball after his first win. For the 26-year-old rookie, it was a nice moment in a season that is getting more comfortable with each outing.

"Yeah, I finally got the fans blocked out, so that's a plus," Lueke said. "Other than that, it's just the new scenario and bigger parks that are more open. That was hard to adjust to at first. But I just got back to thinking it's the same pitching, you're just in a different place now."

Lueke said ignoring the triple-deck stadiums and number of people watching has helped.

"That way it's basically like you're playing catch with your old man in the back yard," he said.

Does he still do that?

"Not in a while," Lueke said with a laugh. "I played catch with him back in January for the first time in years when I first started throwing before [Spring Training]. We were at about 45 feet and I let one go, and he said, 'Uh uh, I'm done.' So that was the end of that."

Figgins sits Tuesday with bruised thumb

SEATTLE -- Third baseman Chone Figgins didn't start on Tuesday after suffering a bruised thumb in the second inning of Monday night's 8-7 victory over Toronto.

Figgins injured his glove hand when a hard line drive by Toronto's Jayson Nix bounced off the base of his thumb on a diving attempt in the top of the second. He stayed in the game and drew a walk in his next at-bat, then left the game after the thumb swelled to the point where he couldn't field ground balls.

Manager Eric Wedge said Figgins was undergoing treatment on Tuesday and held open the outside possibility that he might be available in a reserve role.

"We'll see how the treatment goes," Wedge said. "He's really sore. It's a bad bruise. We'll see on his availability, if any, tonight. Our goal right now is to have him ready to start tomorrow. But we'll see."

Utility infielder Luis Rodriguez started in Figgins' place on Tuesday. Rodriguez had the game-winning two-run single in the bottom of the ninth in Monday's comeback victory.
