BALTIMORE -- On a night when Chris Davis joined the ranks of some of the greatest players in Baltimore Orioles history, his main focus remained on pushing the team toward another playoff run.
Davis hit his major league-leading 40th home run and Nate McLouth belted his first career grand slam, leading the Baltimore Orioles to an 11-8 victory over the Seattle Mariners on Friday night.
Davis hit a third-inning pitch off right-hander Aaron Harang that traveled 442 feet and landed on Eutaw Street. Davis joined Frank Robinson (49), Jim Gentile (46), Rafael Palmeiro (43) and Brady Anderson (50) as the only Orioles to hit 40 homers in a season.
The Orioles also improved to 25-12 when Davis homers.
"It's pretty good company to be in," Davis said. "I am proud of the way things have gone this year. We still have a lot more work to do. It's nice to be a big part of a winning team."
Seattle has now lost four consecutive games after being swept by Boston to open a six-game road trip.
Baltimore starter Chris Tillman (14-3) gave up six runs, which equaled a season high, and eight hits with five strikeouts and three walks in 5 1/3 innings. He improved to 5-0 against his former team.
Adam Jones went 2-for-4 with three RBIs, and Ryan Flaherty picked up three hits, including his seventh home run, for the Orioles.
Seattle designated hitter Kendrys Morales went 4-for-4 with a home run. Humberto Quintero, Michael Morse and Michael Saunders also homered for the Mariners.
Harang (5-10) lasted five innings and allowed seven runs and seven hits with one strikeout and two walks.
"I had a hard time getting loose today," Harang said. "My upper back is tight and it's hard to get extension. Hard to feel like you have control out there. I was pulling a lot of balls. I had to try and overcompensate for pitches I was missing on the arm side."
The Mariners pulled to 7-6 on a sacrifice fly by Saunders in the fifth off Troy Patton. However, McLouth's grand slam in the sixth put the game out of reach.
"I put a pretty good swing on it," McLouth said. "I've been swinging the bat OK but I havent been driving the ball well lately, so it was nice to hit that one out."
The Orioles took the lead in the first inning when Jones' bases-loaded double, which was bobbled by left fielder Raul Ibanez, resulted in three runs. Two batters later, Matt Wieters' sacrifice fly made it 4-0.
The Mariners cut the margin to 4-3 in the third on a two-run homer by Saunders and a two-out RBI single by Morales.
Davis then boosted the Orioles' lead to two runs with a solo shot to right field that was the 72nd in Camden Yarks history to land on Eutaw Street.
"Unfortunately, we were playing catch-up all game long," said Mariners bench coach Robby Thompson, who is managing the team until Eric Wedge returns from a mild stroke. "After that first inning and four hits like that, the only base runner was on an error. (Harang) settled down and made some adjustments. I think if you look back, a lot of those pitches were over the heart of the plate. You do that with this club here, you're gonna run into some problems"
Flaherty provided a 6-3 lead in the fourth when he drove a ball that landed on the flat part of the left-field wall. The umpires eventually ruled it a home run after a brief review.
Quintero answered for Seattle with a leadoff homer in the fifth. However, Jones picked up his third RBI in the bottom of the inning with a single to center that scored Manny Machado.
"We got two games left with these guys and they've been playing pretty good baseball lately, so we aren't gonna take them lightly," Flaherty said. They're going to be two tough games. Then we'll go from there."
NOTES: Roberto Alomar, who was Baltimore's starting second baseman from 1996 to 1998, was inducted into the Orioles Hall of Fame before the game. ... The Orioles' current second baseman, Brian Roberts, was placed on paternity leave to be with his wife, who was expected to give birth to their first child. ... Baltimore RHP Steve Johnson was activated from the 15-day disabled list. ...The Mariners held a closed-door meeting to discuss the team's meltdown the previous night in Boston when the bullpen surrendered six runs in the ninth inning of an 8-7 loss. "That was, to put it lightly, a huge loss," Thompson said.
