Flaherty also had a double and a single, setting a career high with three hits — a fitting performance by an Orioles second baseman on the night Roberto Alomar was inducted into the club's Hall of Fame.

“It's nice for the offense to break out a little bit,” Flaherty said. “Usually when Tilly's pitching, you're not going to need that many. We had a good night offensively and it all worked out.”

The Orioles jumped on Harang early. Each of the first four batters he faced scored — three on a bases-loaded double by Adam Jones. It was Jones' 14th double against the team that traded him to the Orioles in 2008, the most he's had against any opponent that's not in the AL East.

Jones was credited with two RBIs and the third run scored on left fielder Raul Ibanez's error. Jones later scored on a Matt Wieters' sacrifice fly.

The offensive outburst allowed Tillman (14-3) to pick up his 10th victory in 11 decisions despite an uncharacteristically rough outing. Tillman entered the night 4-0 in four starts against his former team, allowing just three runs in 27 2/3 innings.

On Friday night, he gave up three runs in the third inning alone — which included two on one swing by Michael Saunders, who homered for the eighth time this year. The Orioles kept adding to the lead, and Tillman kept allowing the Mariners to stay close.

He was chased in the sixth, giving up six earned runs for just the second time this season.

“I missed early, got out of whack a little bit and struggled to get back in,” Tillman said. “[Making adjustments] is something I've been proud of doing, and it just wasn't there tonight. I couldn't get back in rhythm, couldn't get back in sync. I struggled with all my pitches.”

The Mariners made it close with two solo homers against reliever Francisco Rodriguez in the eighth, but Jim Johnson threw a scoreless ninth for his 38th save.

The game, though, was won once again by the Orioles' ability to homer.

“Everyone knows what our offense is capable of, and they put on a show tonight,” Tillman said. “They really picked this team up. It goes out to them tonight.”
