It was an emotional and historic day of baseball from the Pacific Rim.

The Mariners defeated the A's, 5-4, in a 12-inning affair in Game 2 of MLB's 2019 Opening Series in Japan. Seattle also took Game 1, 9-7, in a slugfest on Wednesday.

Here's a rundown of Thursday's biggest moments:

Seattle jumps in front

Where there's a will, there's a way. After four scoreless innings, the Mariners jumped ahead when the A's couldn't turn a potential inning-ending double play on Domingo Santana's grounder to short. Dee Gordon came home to score, and Hunter Strickland recorded his second straight save.

Ichiro's final salute

Baseball legend Ichiro Suzuki stepped in for the 14,832st and final professional plate appearance of his career in the eighth with a runner on and two outs. In front of a raucous crowd at the Tokyo Dome fully aware of the moment at hand, Ichiro battled in a six-pitch at-bat against A's reliever Lou Trivino before just barely missing out on an infield single.

Ichiro then took the field one last time to begin the bottom of the eighth before jogging off for a final salute. Suzuki's teammates lined up to greet him in front of the Mariners' dugout. He then doffed his cap to the euphoric crowd in Tokyo before stepping into the dugout.

Khrush ties it up

Khris Davis is known for crushing homers, but some nifty two-out hitting from the slugger tied this game up at four. Davis took a Dan Altavilla pitch back up the middle for a two-run ground-ball single to cross 500 RBIs in his career.

Ichiro's third AB

Ichiro stepped in for his third at-bat in the seventh inning. Suzuki struck out looking on a pitch from A's reliever Joakim Soria.

Seattle tacked on another run on Jay Bruce's sacrifice fly to extend its lead to 4-2.

Kikuchi exits with lead

Yusei Kikuchi showed plenty of the talent that convinced the Mariners to acquire him over the offseason, as the southpaw struck out three batters over 4 2/3 innings before exiting in the fifth with a pair of runners on and two outs.

Marcus Semien got the A's on the board with an RBI single to chase Kikuchi. Then, Bruce committed a fielding error at first base that allowed a second Oakland run to score before Stephen Piscotty struck out to end the inning. Kikuchi's night is done with two runs allowed in his Major League debut.

Ichiro steps in a second time

As news spread that Ichiro will indeed be retiring after Thursday's game, the all-time legend stepped in for his second at-bat before a standing ovation in Tokyo. Suzuki grounded out to second to end the top of the fourth.

Haniger goes deep

Mitch Haniger was one of the few Mariners hitters who didn't fill up the box score Wednesday, but he joined the fun in the third inning today with a no-doubt homer to left off Marco Estrada. Haniger's dinger -- Seattle's fourth homer of this series -- extended the Mariners lead to 3-0.

Mariners strike first, Ichiro's first AB

There wasn't any doubt about how Seattle's first runs were scored. Mariners third baseman Ryon Healy drove a hanging breaking ball from Marco Estrada deep into the left-field seats to give his club a 2-0 lead in the second. Ichiro followed in the next at-bat and popped out to Matt Chapman in foul territory.

Kikuchi debuts

After receiving an ovation comparable to Ichiro from the Tokyo Dome crowd, Kikuchi worked a 1-2-3 first inning -- including an athletic play to retire leadoff man Marcus Semien at first base and a strikeout of Matt Chapman -- to get his Major League debut off and running. Ichiro caught the final out of the inning in right field.
