A consensus pick to finish last in the AL West, the Seattle Mariners will spend at least one day of the 2012 season in first place after opening the season with a 3-1, 11-inning triumph over the Oakland A’s in the Tokyo Dome. Dustin Ackley drove in two runs with a home run and an RBI single, but the show belonged to Ichiro.

The capacity crowd of 44,227 a sea of flashbulbs during his every at-bat, Japan’s greatest baseball export thrilled his countrymen with a four-hit night, only the second such performance in an Opening Day game in Mariners history, as Seattle extended its streak of Opening Day wins to six, a franchise record, and the longest such streak in the major leagues.

The Mariners and Athletics entered the 11th inning tied at 1-1, Seattle having gone hitless since the fifth inning. But No. 9 hitter Brendan Ryan opened the frame by driving a fastball from Andrew Carignan into the gap in left center for a double. Chone Figgins then deposited a perfect bunt down the third-base line, sacrificing Ryan to third.

Ackley, who had given the Mariners a 1-0 lead in the fourth inning with a leadoff home run, stroked a single to center, scoring Ryan and staking Seattle to a 2-1 lead.

“I was able to put a good swing on that one,” Ackley said of his 11th inning hit. “Our team is off to a good start, and that’s all that matters.”

“Ackley’s just a good hitter,” said A’s manager Bob Melvin, who skippered the Mariners in 2003-04.  ”He’s going to be one of the better middle-infield hitters in the league at some point in time.”

After Jerry Blevins replaced Carignan, Ichiro laced a shot through the box for his fourth single of the night, scoring Ackley. That made Ichiro the first Seattle batter to produce four hits in an opener since Ken Griffey Jr. in 1990.

“More than the four hits, it was more being able to enjoy the atmosphere with the fans,” Ichiro said through interpreter Antony Suzuki in the Tokyo Dome visitor’s clubhouse. “Being there with the same feelings, that was special to me. That’s what will stay in my heart. Seeing how they welcomed the players, they were very warm-hearted. That makes you cry.”

Closer Brandon League, taking over for Tom Wilhelmsen, the eventual winning pitcher, then worked an almost flawless bottom of the 11th for his first save of the season.

For the Mariners, the only downside to the game was that starter Felix Hernandez (0-0, 1.13 ERA), did not factor in the decision. Hernandez, 14-14 a year ago, allowed just one earned run — an RBI double by Oakland catcher Kurt Suzuki in the bottom of the fourth — on five hits over 8.0 innings. He whiffed six, did not walk a batter, and was the primary reason why the Athletics went a paltry 1-for-14 with runners in scoring position.

“It was a great win, and it was an honor to pitch here in Tokyo,” Hernandez said. “It’s been unbelievable to be here. Great fans and everything. Everyone worked together and it was a great win for us. And all the fans in the stadium, that was pretty good, man. That was awesome.”

Wilhelmsen delivered two perfect innings in relief of Hernandez, striking out two, and then made way for League, who allowed one hit, but fanned two, sending the Mariners into first place.

“What a great show for the fans and obviously for us and the team,” said Wilhelmsen. “It’s just amazing. Felix is the king of Seattle and Washington. But this is just something un-Godly. Ichiro was just amazing and I’m happy he was able to get those four hits and put on the show he did.”

Offensively challenged in 2011, the Mariners had nine hits to Oakland’s six, seven of the nine coming from the top of the order, Figgins (1), Ackley (2), Ichiro (4). Ryan’s 11th-inning double was Seattle’s only hit for extra bases. Seattle stranded 11 runners, but Oakland left 18 men on.

Chad Pennington had two of Oakland’s six hits and scored the A’s only run in the fourth on Suzuki’s double.

The Mariners and Athletics play the second game of their two-game Tokyo series Thursday at 2:10 a.m., Pacific time. The Mariners will send LHP Jason Vargas (10-13, 4.25) to the mound to contest RHP Bartolo Colon (8-10, 4.00).

Following that game, the Mariners will return to Peoria, AZ., to complete spring training. The Mariners and Athletics resume the regular season with a two-game series April 6-7 at the Oakland Alameda Coliseum. Seattle plays its home opener April 13, also against Oakland.
