Not to be forgotten was Scott Sizemore, a fresh face of sorts after missing all of 2012 because of injury. The second baseman, playing in his first big league game since Sept. 28, 2011, picked up a double in his first at-bat.
Overall, eight of the A's starting nine collected at least one hit, proving that the art sometimes really is contagious.
"It's great. We've put ourselves back in position to still split the series, after losing the first two," Young said. "It's definitely nice to get that first win under your belt."
After collecting just three hits in each of their first two games, the A's busted out for 11 on this night, including seven against lefty Joe Saunders, who was chased after four innings.
That let Tommy Milone settle in after a turbulent two-run first inning, and it rewarded him for an impressive turnaround effort in six ensuing shutout frames.
"That's big," Milone said. "It kind of lit a fire under my butt and told me that I needed to keep this game close."
The finesse lefty gave up two solo shots -- one to Franklin Gutierrez and another to Michael Morse -- in the first inning of his 2013 debut, after allowing just six home runs total in the Coliseum last year, before settling down to give up two hits the rest of the way and retiring 17 of the last 18 batters he faced.
His teammates, meanwhile, went to work at the plate, with Lowrie leading the brigade.
The A's shortstop, acquired from the Astros for Chris Carter just two weeks before the start of Spring Training, doubled twice in the first four innings and added a home run -- his first as an Athletic -- to his resume in the seventh, finishing with three RBIs.
Young made it back-to-back home runs with one of his own off righty reliever Kameron Loe to cap off his first start in an A's uniform, his bat clearly not rusty after two days off.
"Jed's been swinging the bat well," manager Bob Melvin said, "and it's nice to get Chris going too and get him on board because he's a heck of a player. When you're on a new team like both those guys are, you want to impress early on. All the way around it was a good game for us today."
It's one Freiman won't soon forget. The first baseman came to the plate for the first time as a big leaguer with Josh Donaldson on third in the second inning, and here's what he was thinking:
"I was trying to not think about how that was my first at-bat in the big leagues," Freiman said. "There's two outs, a runner on third and we're down, 2-0. I really wanted to get that run in. He got ahead of me, 0-2, but I just thought that if I could get something on the barrel, I could do something."
He did, bouncing one up the middle for an RBI single.
"When I got on first," he said, "that's when it all sunk in."
The all-around effort extended to the A's bullpen, where lefty Sean Doolittle emerged for his season debut to shut down the Mariners in the eighth, before Chris Resop was brought out to secure a scoreless ninth.
Freiman, who finished with two hits, summed the day up perfectly.
"That was fun," he said, smiling.
